About 8 out of 10 people entering a community college need to take a refresher mathematics course. if there
are 850 entering students, how many will probably need a refresher mathematics course?

Answers

Answer 1

Approximately 680 out of the 850 entering students will probably need to take a refresher mathematics course which is calculated using simplified fraction.

We are given that about 8 out of 10 people entering a community college need to take a refresher mathematics course. We need to find out how many of the 850 entering students will probably need this course.

Step 1: Determine the proportion of students who need the refresher course.
The proportion is 8 out of 10, which can be written as a fraction: 8/10.

Step 2: Simplify the fraction.
Divide both the numerator (8) and the denominator (10) by their greatest common divisor, which is 2:
8 ÷ 2 = 4
10 ÷ 2 = 5
So, the simplified fraction is 4/5.

Step 3: Calculate the number of students who need the refresher course.
To find the number of students who probably need the course, multiply the total number of entering students (850) by the simplified fraction (4/5):
850 * (4/5) = (850 * 4) / 5 = 3400 / 5 = 680

Diego has a bag with the letters DOG inside. Diego picks 30 letters from the bag, replacing the letter he picks each time. Is it possible that Diego could draw D 19 times, O 10 times, and G 1 time? Why or why not?

Answers

Therefore, it is possible for Diego to draw D 19 times, O 10 times, and G 1 time when picking 30 letters from the bag with replacement, although it is highly unlikely.

What is probability?

Probability is a measure of the likelihood or chance of an event occurring. It is expressed as a number between 0 and 1, with 0 indicating that the event is impossible, and 1 indicating that the event is certain to occur.

Here,

Yes, it is possible for Diego to draw D 19 times, O 10 times, and G 1 time when picking 30 letters from the bag with replacement.

The probability of drawing the letter D on one pick is 1/3, since there is 1 D out of 3 letters in the bag. Similarly, the probability of drawing the letter O on one pick is also 1/3, and the probability of drawing the letter G on one pick is 1/3.

Since Diego replaces each letter he picks, the probability of drawing D 19 times in a row is (1/3)¹⁹, the probability of drawing O 10 times in a row is (1/3)¹⁰, and the probability of drawing G 1 time is 1/3.

The probability of all these events happening in this order is the product of their individual probabilities, which is:

(1/3)¹⁹ * (1/3)¹⁰ * 1/3 = (1/3)³⁰

This probability is very small, but it is still greater than zero.

A shipping container is in the shape of a right rectangular prism with a length of 11. 5


feet, a width of 8. 5 feet, and a height of 7 feet. The container is completely filled with


contents that weigh, on average, 0. 32 pound per cubic foot. What is the weight of the


contents in the container, to the nearest pound?

Answers

The weight of the contents in the container is approximately 222 pounds when rounded to the nearest pound.

The weight of the contents in the container can be calculated using the formula:

Weight = Volume x Density

First, we need to find the volume of the container, which is simply the product of its length, width, and height:

Volume = 11.5 x 8.5 x 7 = 696.5 cubic feet

Next, we need to multiply the volume by the density of the contents:

Weight = 696.5 x 0.32 = 222.08 pounds

It's important to note that the weight may vary depending on the actual density of the contents. Additionally, it's also important to consider the weight of the container itself, which would add to the total weight of the shipment.

(b) Compute the second derivative of / L'(x) = (e) On what interval is concave downward? interval of downward concavity = () On what interval is concave upward? interval of upward concavity = **Show work, in detail, on the scrap paper to receive full credit.

Answers

(a) The first derivative of f is f'(x) = 3x² - 15.

(b) The second derivative of f is f''(x) = 6x.

(c) f is increasing on the interval (-∞, √5) and decreasing on the interval (√5, ∞).

(d) f is decreasing on the interval (-∞, √5) and increasing on the interval (√5, ∞).

(e) f is concave downward on the interval (-∞, 0) and concave upward on the interval (0, ∞).

(a) To find the first derivative of f, we differentiate each term of the function with respect to x using the power rule. Thus, f'(x) = 3x² - 15.

(b) To find the second derivative of f, we differentiate f'(x) with respect to x. Thus, f''(x) = 6x.

(c) To determine the intervals where f is increasing, we set f'(x) > 0 and solve for x. Thus, 3x² - 15 > 0, which simplifies to x² > 5. Therefore, x is in the interval (-∞, √5) or (√5, ∞). To determine which interval makes f increasing, we can test a point within each interval.

For example, when x = 0, f'(0) = -15, which is negative, so f is decreasing on (-∞, √5). When x = 10, f'(10) = 285, which is positive, so f is increasing on (√5, ∞). Thus, f is increasing on the interval (√5, ∞) and decreasing on the interval (-∞, √5).

(d) To determine the intervals where f is decreasing, we set f'(x) < 0 and solve for x. Thus, 3x² - 15 < 0, which simplifies to x² < 5. Therefore, x is in the interval (-∞, √5) or (√5, ∞). Again, we can test a point within each interval to determine which one makes f decreasing.

For example, when x = 0, f'(0) = -15, which is negative, so f is decreasing on (-∞, √5). When x = 10, f'(10) = 285, which is positive, so f is increasing on (√5, ∞). Thus, f is decreasing on the interval (-∞, √5) and increasing on the interval (√5, ∞).

(e) To determine the intervals of concavity, we examine the sign of the second derivative of f. If f''(x) > 0, then f is concave upward, and if f''(x) < 0, then f is concave downward. If f''(x) = 0, then the concavity changes. Thus, we set f''(x) > 0 and f''(x) < 0 and solve for x. We get f''(x) > 0 when x > 0 and f''(x) < 0 when x < 0.

Therefore, f is concave upward on (0, ∞) and concave downward on (-∞, 0).

The function models the amount of money a new business has made over x months. Negative values represent debt. Over what interval is the amount increasing?

Answers

If the line has a positive slope, it means that the amount is increasing, and if it has a negative slope, it means that the amount is decreasing.

Based on the given information, the function models the amount of money a new business has made over x months. Therefore, we can assume that the function is a linear function, and its graph is a straight line.

Given that negative values represent debt, we can assume that the slope of the line is positive over the interval where the function takes positive values. Therefore, the interval over which the amount is increasing is from zero to infinity, which means that the business is making money and not in debt.

It's essential to note that if the function has a negative slope over any interval, then the amount is decreasing, and the business is losing money. However, we cannot determine this information from the given function's information.

Answers

Answer:

Step-by-step explanation:

The missing numbers are: box 1 = -5x and box 2 = 4sot,  A diamond problem is a type of math puzzle that involves finding two missing values in a diamond-shaped diagram.

The top and bottom numbers of the diamond represent a product, and the left and right sides represent two numbers that add up to a middle value. The goal is to find the two missing values that fit into the diamond.

To solve a diamond problem, we need to factor the product of the top and bottom numbers and look for two factors whose sum is equal to the middle value. This is because the product of two numbers can only be made up of factors that multiply together to form the product. Once we find the two factors, we can insert them into the left and right sides of the diamond.

In the given diamond problem, we have 20x? as the top and sot as the bottom. The product of these two numbers is 20x^2sot. To find the factors, we can list all the possible factor pairs of this product and check which of them adds up to -9x, which is the middle value in the diamond. We found that -5x and 4sot are the factors that add up to -9x.

Solving diamond problems can help improve factoring skills and problem-solving abilities. It requires logical thinking and an understanding of how factors and multiples work. Additionally, diamond problems can be used to introduce algebraic concepts to students in a visual and intuitive way, making them a useful tool for teaching math to learners of all ages.

Willow bought 3 m of denim fabric and 5m of cotton


fabric. The total bill, excluding tax, was $22. Jared


bought 6 m of denim fabric and 2 m of cotton fabric


at the same store for $28. How much does the denim


fabric cost? How much does the cotton fabric cost?



How do I start?

Answers

The denim fabric costs $4 per meter and the cotton fabric costs $3 per meter.

To find out the cost per meter of each type of fabric, we can set up a system of two equations. Let d be the cost per meter of denim fabric and c be the cost per meter of cotton fabric. Then, we have:

3d + 5c = 22 (equation 1)

6d + 2c = 28 (equation 2)

We can use equation 2 to solve for one of the variables in terms of the other. Solving for c, we get:

c = 14 - 3d (equation 3)

We can substitute equation 3 into equation 1 and solve for d:

3d + 5(14 - 3d) = 22

Simplifying this equation, we get:

4d = 3

Therefore, d = 0.75, which means the denim fabric costs $0.75 per meter.

We can then use equation 3 to find the cost per meter of cotton fabric:

c = 14 - 3(0.75) = 11.25/2 = $5.625

Therefore, the cotton fabric costs $5.625 per meter.

if two samples a and b had the same mean and standard deviation, but sample a had a larger sample size, which sample would have the wider 95% confidence interval?

Answers

As a result of being more dispersed, sample A has a broader 95% confidence interval.

Given that sample A had a higher standard deviation and that we are aware that when standard deviation rises, the margin of error likewise does, widening the confidence interval as a result.

The average squared departure of each observation from the mean is the standard deviation's square root.  In other words, it tells you how much the data points deviate from the average value.

Standard deviation is often used as a tool in statistical analysis to help determine the reliability of data. For example, if you were measuring the heights of a group of people, a low standard deviation would suggest that the majority of the people are around the same height, while a high standard deviation would suggest that there is a wider range of heights in the group.

f. ) Suppose Amtrak is considering adding a stop to the Coast Starlight 500 miles away from Los Angeles. Would it be appropriate to use this linear model to predict the travel time from Los Angeles to tis point?

Answers

a) The equation of the regression line is Travel Time = β₀ + β₁(Distance Traveled) + ɛ. b) The slope of the regression line indicates the increase in travel time and the intercept represents the estimated travel time. c) R₂ is 0.404. d) Regression equation will be used. e) Residual cannot be calculated. f) No, the given linear model is not appropriate to use.

a) The equation of the regression line for predicting travel time is

Travel Time = β₀ + β₁(Distance Traveled) + ɛ

where β₀ is the intercept, β₁ is the slope, Distance Traveled is the independent variable, and Travel Time is the dependent variable.

b) The slope of the regression line indicates the increase in travel time (in minutes) for every one-mile increase in distance traveled. The intercept represents the estimated travel time (in minutes) when the distance traveled is zero. In this context, the intercept is not meaningful since there cannot be a distance of zero between two stops.

c) To calculate R₂, we need to first calculate the correlation coefficient (r) between Travel Time and Distance Traveled

r = (covariance of Travel Time and Distance Traveled) / (standard deviation of Travel Time × standard deviation of Distance Traveled)

Using the given values, we have

r = (0.636 × 113 × 99) / (113 × 99) = 0.636

Then, we can calculate R₂ as

R₂ = r₂ = 0.6362 = 0.404

R₂ represents the proportion of variance in Travel Time that is explained by Distance Traveled. In this context, R₂=0.404 indicates that 40.4% of the variation in travel time from one stop to the next on the Coast Starlight can be explained by the distance traveled between those stops.

d) To estimate the time it takes for the Starlight to travel between Santa Barbara and Los Angeles, we need to use the regression equation

Travel Time = β₀ + β₁(Distance Traveled)

We know that the distance between Santa Barbara and Los Angeles is 103 miles. So, we plug this value into the equation

Travel Time = β₀ + β₁(103)

To solve for the travel time, we need to know the values of β₀ and β₁. We can use the given mean and standard deviation values to estimate these parameters using linear regression. However, we are not given this information in the question.

e) To calculate the residual, we need to first calculate the predicted travel time based on the regression equation

Travel Time = β₀ + β₁(Distance Traveled)

We are told that the distance between Santa Barbara and Los Angeles is 103 miles, so we can plug this value into the equation to get the predicted travel time

Predicted Travel Time = β₀ + β₁(103)

However, we are not given the values of β₀ and β₁, so we cannot calculate the predicted travel time.

The residual is the difference between the actual travel time and the predicted travel time. In this case, we are told that the actual travel time is 168 minutes, and we do not have the predicted travel time. Therefore, we cannot calculate the residual.

f) It would not be appropriate to use this linear model to predict the travel time from Los Angeles to a point 500 miles away from Los Angeles, because the linear relationship between travel time and distance traveled may not hold beyond the range of distances that were used to estimate the regression equation. The linear model assumes that the relationship between travel time and distance traveled is constant across all distances, which may not be true. Additionally, adding a stop at a point 500 miles away from Los Angeles may affect the relationship between travel time and distance traveled, since there may be other factors that influence travel time at that distance. Therefore, a new regression model would need to be estimated using data that includes stops at or beyond the 500-mile mark.

Answers

The function is neither even nor odd.

To find f(-x), we substitute -x for x in the function f(x):

f(-x) = (-x)^3 - 7/(-x) = -x^3 - 7/x

To find -f(x), we multiply the function f(x) by -1:

-f(x) = -1 * (x^3 - 7/x) = -x^3 + 7/x

To determine if the function is even, odd or neither, we compare f(-x) and -f(x).

If f(-x) = f(x), the function is even.

If f(-x) = -f(x), the function is odd.

If neither of these is true, the function is neither even nor odd.

Comparing f(-x) and -f(x), we have:

f(-x) = -x^3 - 7/x

-f(x) = -x^3 + 7/x

A circle with center c(2, 4) has radius 13. a) verify that a(14,9) and b(7, 16) are points on this circle. b) if m is the midpoint of ab, show that cm is perpendicular to ab.

Answers

a) To verify that the points A(14, 9) and B(7, 16) are on the circle with center C(2, 4) and radius 13, we can use the distance formula:

Distance between point A and C:

d_AC = sqrt[(x_A - x_C)^2 + (y_A - y_C)^2]

    = sqrt[(14 - 2)^2 + (9 - 4)^2]

    = sqrt[144 + 25]

    = sqrt(169)

    = 13

Since the distance between point A and C is equal to the radius of the circle, point A is on the circle.

Distance between point B and C:

d_BC = sqrt[(x_B - x_C)^2 + (y_B - y_C)^2]

    = sqrt[(7 - 2)^2 + (16 - 4)^2]

    = sqrt[25 + 144]

    = sqrt(169)

    = 13

Since the distance between point B and C is equal to the radius of the circle, point B is also on the circle.

Therefore, points A and B are on the circle with center C(2, 4) and radius 13.

b) The midpoint of line segment AB can be found using the midpoint formula:

M = [(x_A + x_B)/2, (y_A + y_B)/2]

 = [(14 + 7)/2, (9 + 16)/2]

 = [10.5, 12.5]

The slope of line segment AB can be found using the slope formula:

m_AB = (y_B - y_A)/(x_B - x_A)

    = (16 - 9)/(7 - 14)

    = -7/-7

    = 1

The slope of a line perpendicular to AB will be the negative reciprocal of m_AB:

m_CM = -1/m_AB

    = -1/1

    = -1

The equation of the line passing through points C(2, 4) and M(10.5, 12.5) can be found using the point-slope form:

y - y_C = m_CM(x - x_C)

y - 4 = -1(x - 2)

y = -x + 6

The slope of line CM is -1, which is the negative reciprocal of the slope of line AB. Therefore, line CM is perpendicular to line AB.

Hence, we have shown that line segment CM is perpendicular to line segment AB.

If you spin a spinner 75 times, how many multiples of 2?

Answers

If you spin a spinner 75 times, the number of multiples of 2 could be either 7 or 38.

Assuming the spinner has an equal chance of landing on any number from 1 to 6, we can find the probability of landing on a multiple of 2 (2, 4, or 6) by dividing the number of multiples of 2 by the total number of possible outcomes:

Number of multiples of 2 = 3
Total number of possible outcomes = 6

So the probability of landing on a multiple of 2 is:

P(multiple of 2) = 3/6 = 1/2

This means that out of 75 spins, we can expect to land on a multiple of 2 about half the time. To find the exact number, we multiply the probability by the number of spins:

Number of multiples of 2 = P(multiple of 2) x Number of spins
Number of multiples of 2 = (1/2) x 75 = 37.5

Since we can't have a fraction of a spin, we need to round to the nearest whole number. In this case, we can round up or down depending on how we interpret the question. I

f we want to know how many times we can expect to land on a multiple of 2 on average, we should round down to 37.

If we want to know the closest integer to the expected value, we should round up to 38.

So depending on the context of the question, the answer could be either 37 or 38.

determine the length of the fence along the front part of the land that will be cost $60 per meter.

(give your answer as a whole or exact number.)

Answers

To minimize the cost of the fence, the builder should use the expensive fence along the shorter side of the rectangular shape, as this will require less length of the expensive fence. Let's say the length of the rectangle is x meters and the width is y meters. Then the area of the rectangle is given by:

A = xy = 80000

And the perimeter of the rectangle is:

P = 2x + 2y

We are given that the cost of the fence along the front part of the land will cost $60 per meter, while the fence for the other three sides will cost $20 per meter. So the total cost of the fence is:

C = 60x + 20(2x + 2y)

Simplifying this expression, we get:

C = 100x + 40y

We can now use the area equation to eliminate one of the variables. Solving for y, we get:

y = 80000/x

Substituting this expression for y into the cost equation, we get:

C = 100x + 40(80000/x)

Simplifying this expression, we get:

C = 100x + 3200000/x

To minimize this function, we need to take its derivative and set it equal to zero:

dC/dx = 100 - 3200000/x^2 = 0

Solving for x, we get:

x = sqrt(32000) = 178.89

So the length of the rectangle should be approximately 178.89 meters, and the width should be:

y = 80000/178.89 = 446.68

Therefore, the amount of expensive fence needed is 178.89 meters, and the amount of cheap fence needed is:

2(178.89) + 2(446.68) - 178.89 = 893.36 meters

Finally, the length of the fence along the front part of the land that will be cost $60 per meter is simply the width of the rectangle, which is:

y = 446.68 meters (rounded to two decimal places)

The corresponding values for the triangle in the larger circle are;

1. Perimeter of Δ BSH = 71.4 cm

2. The measure of ∠SBH = 102°.

3.  The area of Δ BSH = 41.54 cm²

4. The length of the circumference of circle B = 52.275 cm

How do you calculate the corresponding values for the triangle in the larger circle, like perimeter?

1. The ratio of the perimeters of similar triangles is equal to the ratio of their corresponding sides. Since OB/OA = 4.25, we have:

Perimeter(Δ BSH) = Perimeter(Δ ARG) × 4.25

Perimeter(Δ BSH) = 16.8 cm × 4.25 = 71.4 cm

2. Since the triangles are similar, their corresponding angles are congruent. Therefore, ∠SBH = ∠RAG = 102°.

3. The ratio of the areas of similar triangles is equal to the square of the ratio of their corresponding sides. Since OB/OA = 4.25, we have:

Area(Δ BSH) = Area(Δ ARG) × (4.25)²

Area(Δ BSH) = 2.3 cm² × (4.25)² = 2.3 cm² × 18.0625 = 41.54 cm²

4. The ratio of the circumferences of similar circles is equal to the ratio of their radii or diameters. Since OB/OA = 4.25, we have:

Circumference(circle B) = Circumference(circle A) × 4.25

Circumference(circle B) = 12.3 cm × 4.25 = 52.275 cm

The above answers are in response to the following questions below;

The choir practiced 3 times this week. On Monday,the choir practiced 3/4 hour. On Wednesday, they practiced 1/2 hour more than on Monday. On Friday, they practiced twice as long as on both Monday and Wednesday combined. Altogether,how long did the choir practice this week?

Answers

The choir practice this week for 5 1/4 hours.

On Monday, the choir practiced for 3/4 hour.

On Wednesday, they practiced for 1/2 hour more than on Monday, which is 3/4 + 1/2 = 6/8 + 4/8 = 10/8 = 1 1/4 hours.

On Friday, they practiced twice as long as on both Monday and Wednesday combined, which is 2 * (3/4 + 1 1/4) = 2 * 2 = 4 hours.

To find the total practice time for the week, we can add up the times from each day:

3/4 + 1 1/4 + 4 = 5 + 1/4 = 5 1/4 hours.

Therefore, the choir practiced for 5 1/4 hours in total this week.

Prepare a mixture of 100g of 8% cream into 200g of 3% cream. What is the resulting concentration?


(Pharmacy technician math)

Answers

The resulting concentration from the mixture will be: 4.67%

How to obtain the concentration of the mixture

To obtain the concentration of the mixture, we will multiply the volumes of the substances by their percentages and then equate the result that we get to the sum of the mixture. This gives us:

100 g * 0.08 + 200 g * 0.03 = (100 + 200) C

8 + 6 = 300C

= 14 = 300 C

C = 14/300

= 0.046

This could be rewritten in the form of a percentage as 4.67%.

So, the resulting concentration of the solution will be 4.67%.

The path the rover travels out of the crater is a distance of 180 m and covers a vertical distance of 65 meters, determine the angle of elevation of the room to the nearest thousands of degree

Answers

The angle of elevation of the room is approximately 19.1 degrees.

To determine the angle of elevation of the room, we need to use trigonometry. The angle of elevation is the angle between the horizontal plane and the line of sight from the rover to the room. We can use the tangent function to find this angle:

tan(angle of elevation) = opposite/adjacent

In this case, the opposite side is the vertical distance of 65 meters and the adjacent side is the horizontal distance of 180 meters. So we have:

tan(angle of elevation) = 65/180

To find the angle of elevation, we can take the inverse tangent (or arctan) of both sides:

angle of elevation = arctan(65/180)

Using a calculator, we get:

angle of elevation = 19.1 degrees (rounded to the nearest thousands of degree)

Therefore, the angle of elevation of the room is approximately 19.1 degrees.
