16 students at a school were asked about their favorite pasta dish. A graph of the results is on the left.
Create a bar graph showing the possible results for all 400 students in the school. Be sure to number the vertical axis.
Answer:
Step-by-step explanation:
to solve this question, we need to use the graph on the left to find the proportions of students who prefer each pasta dish, and then multiply those proportions by 400 to get the estimated number of students in the whole school who prefer each pasta dish. Then we need to plot those numbers on a bar graph with the pasta dishes on the horizontal axis and the number of students on the vertical axis. The graph below shows one possible way to create the bar graph:
We can see that the vertical axis is numbered from 0 to 120 in increments of 20. The bars show the estimated number of students who prefer each pasta dish, based on the sample of 16 students. For example, since 4 out of 16 students prefer spaghetti, we can estimate that 4/16 x 400 = 100 students in the whole school prefer spaghetti. Similarly, since 3 out of 16 students prefer lasagna, we can estimate that 3/16 x 400 = 75 students in the whole school prefer lasagna. We can repeat this process for the other pasta dishes and plot them on the graph.

Instructors led an exercise class from a raised rectangular platform at the front of the room. The width of the platform is (x+4) meters long and the area of the rectangular platform is 3x^2+10x−8. Find the length of the platform
The length of the platform is given by the expression -2 + sqrt(3x^2 + 10x) meters.
Let's start by using the formula for the area of a rectangle, which is:
Area = length x width
We are given that the width of the platform is (x+4) meters, so we can write:
Area = length x (x+4)
We are also given that the area of the platform is 3x^2+10x−8, so we can set these two expressions equal to each other and solve for the length:
3x^2+10x−8 = length x (x+4)
Expanding the right side, we get:
3x^2+10x−8 = length x^2 + 4length
Subtracting 4length from both sides, we get:
3x^2+10x−8−4length = length x^2
Rearranging, we get a quadratic equation:
length x^2 + 4length − 3x^2 − 10x + 8 = 0
To solve for length, we can use the quadratic formula:
length = (-b ± sqrt(b^2 - 4ac)) / 2a
where a = 1, b = 4, and c = -3x^2 - 10x + 8. Plugging in these values, we get:
length = (-4 ± sqrt(4^2 - 4(1)(-3x^2 - 10x + 8))) / 2(1)
Simplifying under the square root:
length = (-4 ± sqrt(16 + 12x^2 + 40x - 32)) / 2
length = (-4 ± sqrt(12x^2 + 40x)) / 2
length = (-4 ± 2sqrt(3x^2 + 10x)) / 2
length = -2 ± sqrt(3x^2 + 10x)
Since the length must be positive, we take the positive square root:
length = -2 + sqrt(3x^2 + 10x)
Therefore, the length of the platform is given by the expression -2 + sqrt(3x^2 + 10x) meters.

$3,900 at 1% compounded annually for 6 years
Answer:
$4139.93
Step-by-step explanation:
Formula for amount accrued at compound interest annually is given by
A = P( 1+ r)ⁿ
where
P = principal
r = interest rate expressed as a decimal
n = number of years
Given P = 3900, r = 1/100 = 0.01, n = 6 we get
A = 3900(1 + 0.01)⁶ = 3900(1.01)⁶ = 4139.93
So the amount accrued after 6 years = $4139.93
The function C(x) = 25x2 - 98x shows the cost of printing magazines (in dollars) per day at a printing press. What is the rate of change of cost when the number of magazines printed per day is 17?
A. 327$/print
B. 552$/print
C. 752$/print
D. 227$/print
The rate of change of cost when the number of magazines printed per day is 17 is 752 dollars per print. The correct option is C.
The function C(x) = 25x² - 98x represents the cost of printing magazines per day at a printing press. To find the rate of change of cost when 17 magazines are printed per day, we need to calculate the derivative of the function with respect to x (the number of magazines printed), which represents the rate of change at a given point.
The derivative of C(x) with respect to x can be found using the power rule for differentiation. For a function of the form f(x) = [tex]ax^n[/tex], its derivative is f'(x) = [tex]n*ax^{(n-1)[/tex].
Applying the power rule to our function, we get:
C'(x) = 2(25x) - 98 = 50x - 98.
Now, we need to evaluate C'(x) when x = 17 (the number of magazines printed per day):
C'(17) = 50(17) - 98 = 850 - 98 = 752.
Therefore, the rate of change of cost when the number of magazines printed per day is 17 is 752 dollars per print. So, the correct answer is: C. 752$/print.

If you remove the outlier: 8
- the range will stay the same: false
- the mean will decrease: false
- the median will increase: true
The statements are classified as follows:
- the range will stay the same: false- the mean will decrease: false- the median will increase: true.How to obtain the features of the data-set?The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations, which is also called the cardinality of the data-set.
8 is a low outlier, hence it is a value lower than the mean, meaning that the mean increases if we remove the observation of 8.
The range of a data-set is calculated as the difference between the highest value and the lowest value in the data-set, thus if we remove the low value of 8, the next low value is of 47, meaning that the range decreases.
The ordered data-set is given as follows:
8, 47, 48, 50, 51, 51.
The data-set has an even cardinality of 6, hence the median is calculated as the mean of the two middle elements as follows:
Median = (48 + 50)/2
Median = 49.
Removing 8, the data-set is given as follows:

The Fourier series Using the complex form of f(x) is
f(x) = 1/2 + ∑[n=1, ∞] [2*(-1)^(n+k)/(nπ)]*sin(nπx), 2k-0.25 < x < 2k+0.25
where k is an integer.
To find the Fourier series of the function f(x) over the interval [-1, 1], we first note that f(x) is periodic with period T = 0.5. We can then write f(x) as a Fourier series of the form
f(x) = a0/2 + ∑[n=1, ∞] (ancos(nπx) + bnsin(nπx))
where
a0 = (1/T) ∫[0,T] f(x) dx
an = (2/T) ∫[0,T] f(x)*cos(nπx) dx
bn = (2/T) ∫[0,T] f(x)*sin(nπx) dx
Since f(x) = 0 for x < -0.25 and x > 0.25, we only need to consider the interval [-0.25, 0.25]. We can break this interval into subintervals of length 0.5 centered at integer values k
[-0.25, 0.25] = [-0.25, 0.25] ∩ [1.5, 2.5] ∪ [-0.25, 0.25] ∩ [0.5, 1.5] ∪ ... ∪ [-0.25, 0.25] ∩ [-1.5, -0.5]
For each subinterval, the Fourier coefficients can be calculated as follows
a0 = (1/0.5) ∫[-0.25, 0.25] f(x) dx = 1/2
an = (2/0.5) ∫[-0.25, 0.25] f(x)*cos(nπx) dx = 0
bn = (2/0.5) ∫[-0.25, 0.25] f(x)sin(nπx) dx = 2(-1)^k/(nπ)
Therefore, the Fourier series of f(x) is
f(x) = 1/2 + ∑[n=1, ∞] [2*(-1)^(n+k)/(nπ)]*sin(nπx), 2k-0.25 < x < 2k+0.25

The function f(x) models the height in feet of the tide at a specific location x hours after high tide.

a. What is the height of the tide at low tide?
b. What is the period of the function? What does this tell you about the tides at this location?
c. How many hours after high tide is the tide at the height of 3 feet for the first time?
a) The height of the tide at low tide is 3.7 feet.
b) The period of the function is 12 hours and it means that the tide goes through a full cycle of high tide.
c) The first time the tide reaches a height of 3 feet is therefore either 23.82 hours or 40.18 hours after high tide.
a. To find the height of the tide at low tide, we need to find the minimum value of the function f(x).
Since cos(π/6 x) has a maximum value of 1 and a minimum value of -1, the minimum value of the entire function occurs when cos(π/6 x) = -1.
This happens when π/6 x = π + 2nπ, where n is any integer.
Solving for x, we get x = 12 + 12n.
Substituting this value of x into the function, we get f(x) = 0 + 3.7 = 3.7 feet.
b. The period of the function is the time it takes for the function to complete one full cycle. Since the period of cos(π/6 x) is 2π/π/6 = 12 hours, the period of the entire function f(x) is also 12 hours. This means that the tide goes through a full cycle of high tide and low tide every 12 hours at this location.
c. To find the first time the tide reaches a height of 3 feet, we need to solve the equation 3 = 3.5 cos (π/6 x) + 3.7 for x.
Subtracting 3.7 from both sides and dividing by 3.5, we get cos(π/6 x) = -0.086.
Taking the inverse cosine of both sides, we get π/6 x = 1.67 + 2nπ or π/6 x = -1.67 + 2nπ, where n is any integer.
Solving for x, we get x = 40.18 + 24n or x = 23.82 + 24n.
The first time the tide reaches a height of 3 feet is therefore either 23.82 hours or 40.18 hours after high tide.

The quantity of a substance can be modeled by the function R(t) that satisfies the differential equation dR/dt= -1/5(R – 20). One point on this function is R(2) = 35. Based on this model, use a linear approximation to the graph of Rat t = 2 to estimate the quantity of the substance at t 1.9. \
The estimated quantity of the substance at t = 1.9 is approximately 35.3 units.
To estimate the quantity of the substance at t = 1.9 using linear approximation, we can use the formula:
ΔR ≈ dR/dt * Δt
Given the point R(2) = 35 and the differential equation dR/dt = -1/5(R – 20), we can first find the value of dR/dt at t = 2.
dR/dt(2) = -1/5(R(2) – 20) = -1/5(35 – 20) = -1/5(15) = -3
Now, we can calculate Δt, which is the difference between the given t-value (2) and the desired t-value (1.9):
Δt = 1.9 - 2 = -0.1
Next, we can calculate ΔR using the linear approximation formula:
ΔR ≈ dR/dt * Δt ≈ -3 * (-0.1) = 0.3
Finally, we can estimate the quantity of the substance at t = 1.9 by adding ΔR to the given value of R(2):
R(1.9) ≈ R(2) + ΔR ≈ 35 + 0.3 = 35.3
Therefore, the estimated quantity of the substance at t = 1.9 is approximately 35.3 units.

For what values of a and b will this equation have infinitely many solutions?
5(x + 3) = a(x + 4) + 3x + b
Answer: To have infinitely many solutions, the equation must be true for all values of x. In other words, the left side and right side of the equation must be equivalent, meaning that the coefficients of x on both sides of the equation must be equal, and the constant terms on both sides must be equal.
We can simplify the given equation as follows:
5(x + 3) = a(x + 4) + 3x + b
5x + 15 = ax + 4a + 3x + b
Simplifying further, we get:
8x + 4a + b = 5x + 15
Rearranging terms, we get:
3x + 4a + b - 15 = 0
For this equation to have infinitely many solutions, the coefficients of x on both sides must be equal to zero, meaning that:
3 = 0
This is not possible, so the equation cannot have infinitely many solutions for any values of a and b.
Therefore, there are no values of a and b for which the given equation will have infinitely many solutions.
Neave is designing a prize wheel for her school. 200 students will each spin the wheel once. Neave wants the expected number of winners to be 60.
If the wheel is split into 40 equally sized sections, how many sections should be marked “win”
Neave should mark 12 sections as "win" on the prize wheel to achieve the expected number of winners of 60 out of 200 students.
To determine how many sections should be marked "win" on Neave's prize wheel, we need to consider the expected number of winners and the total number of sections on the wheel.
Neave wants the expected number of winners to be 60 out of 200 students. This means that the probability of winning should be 60/200 = 0.3 or 30%.
If the wheel is split into 40 equally sized sections, we can assume that each section has an equal probability of being selected by a student. Therefore, to have a 30% chance of winning, we need to mark a proportionate number of sections as "win".
To calculate the number of sections to mark as "win", we multiply the total number of sections by the desired probability of winning:
40 sections * 0.3 = 12 sections.
It's important to note that the concept of expected value assumes an idealized scenario with perfect randomness. In reality, the actual number of winners may vary due to random chance and individual spin outcomes.

The student's use of the t procedure for a confidence interval was appropriate because the sample size was greater than 30 and the population standard deviation was unknown. A 95% confidence interval was calculated using the t-distribution.
It was an appropriate use of the t procedure for a confidence interval. The student wanted to assess the average time spent studying for his most recent exam taken in class, and he used a sample of 45 students to estimate the population mean with a 95% confidence interval.
Since the population standard deviation is not known, the student used the t-distribution to calculate the confidence interval. The t-distribution is used when the sample size is small, and the population standard deviation is unknown.
The student assumed that the sample was randomly selected, and the data was approximately normally distributed. By using the t procedure, the student was able to estimate the population mean with a margin of error and a level of confidence of 95%.

She wants to play cornhole, but she does not have enough pink bean bags
with her set. However, Sarah keeps a box of spare bean bags in her garage. If
the box contains one yellow, four blue, three red and two pink bean bags,
what is the probability to the nearest tenth of a percent that she will select
the two pink bean bags from the box on her first two attempts?
The probability that she will select the two pink bean bags from the box on her first two attempts is approximately 2.2%.
To calculate the probability that she will select the two pink bean bags from the box on her first two attempts, we need to;
1. Determine the total number of bean bags in the box. There is one yellow, four blue, three red, and two pink bean bags, which makes a total of 1 + 4 + 3 + 2 = 10 bean bags.
2. Calculate the probability of selecting a pink bean bag on the first attempt. There are two pink bean bags out of 10, so the probability is 2/10 or 1/5.
3. After selecting one pink bean bag, there are now nine bean bags left in the box. Calculate the probability of selecting the second pink bean bag on the second attempt. Since there is only one pink bean bag left, the probability is 1/9.
4. To find the overall probability of selecting two pink bean bags in the first two attempts, multiply the probabilities from steps 2 and 3. So, the probability is (1/5) * (1/9) = 1/45.
5. Convert the fraction to a percentage by dividing the numerator by the denominator and multiplying by 100. (1/45) * 100 = 2.22% (rounded to the nearest tenth of a percent).

The base of a prism is a right triangle with legs measuring 3 feet and 4 feet. If the height of the prism is 13 feet, determine its volume
The volume of the prism is 78 cubic feet.The volume of a prism is given by the formula V = Bh, where B is the area of the base and h is the height of the prism.
In this case, the base of the prism is a right triangle with legs measuring 3 feet and 4 feet, so its area is (1/2)(3)(4) = 6 square feet. The height of the prism is 13 feet. Therefore, the volume of the prism is V = Bh = (6)(13) = 78 cubic feet.To understand this calculation, think of the prism as a stack of identical, parallel cross sections. Each cross section is a copy of the base, with an area of 6 square feet.
The height of each cross section is the same, and equal to the height of the prism, which is 13 feet. To find the total volume of the prism, we add up the volumes of all these cross sections, which is equal to the area of the base times the height of the prism.

The combined math and verbal scores for females taking the SAT-I test are normally distributed with a mean of 998 and a standard deviation of 202 (based on date from the College Board). If a college includes a minimum score of 925 among its requirements, what percentage of females do not satisfy that requirement?
The percentage of females who do not satisfy the minimum score requirement of 925 on the SAT-I test is 35.9%.
Calculating the z-score for the minimum score requirement:
z = (X - Mean) / Standard Deviation
z = (925 - 998) / 202
z = -73 / 202 ≈ -0.361
Now, using the z-score to find the percentage of females below the minimum score:
Since the z-score is -0.361, we can use a z-table (or an online calculator) to find the area to the left of this z-score, which represents the percentage of females who scored below 925. The area to the left of -0.361 is approximately 0.359.
3. Convert the area to a percentage:
Percentage = Area * 100
Percentage = 0.359 * 100 ≈ 35.9%
So, approximately 35.9% of females do not satisfy the minimum score requirement of 925 on the SAT-I test.

Your school newspaper has an editor-in-chief and an assistant editor-in-chief. The newspaper staff
has 5 students. How many different ways can students be chosen for these positions?
There are 20 different ways the students can be chosen for the positions of editor-in-chief and assistant editor-in-chief.
There are 5 students in the newspaper staff, and two positions to fill i.e. editor-in-chief and assistant editor-in-chief. We need to find the number of different ways the students can be chosen for these positions.
To solve this problem, we can use the formula for permutation
We know the formula for Permutation is
[tex]P(n,r)=\frac{n!}{(n-r)!}[/tex]
Here, n=5 and r=2
So, P(5,2) = 5!/(5-2)!
= 5!/3!
= 120/6
= 20
Therefore, there are 20 different ways the students can be chosen for the positions of editor-in-chief and assistant editor-in-chief.

Amelia read 5 books in 3 months. what was her rate of reading in books per month?
also where should i resize the right columns represent the unit rate?
Amelia's rate of reading was approximately 1.67 books per month (calculated by dividing the total number of books, 5, by the number of months, 3).
How many books did Amelia read per month, and where should I resize the columns to represent the unit rate?To calculate Amelia's rate of reading in books per month, we divide the total number of books she read (5) by the number of months (3). Therefore, her rate of reading is 5/3 books per month.
To resize the right columns to represent the unit rate, you would need to scale them down. If the left column represents the number of months and the right column represents the number of books read, you could adjust the scale so that each unit on the right column represents 1 book per month.
For example, if each square unit on the left column represents 1 month and each square unit on the right column represents 0.5 books, you could resize the right column so that each square unit represents 1 book. This would ensure that the visual representation accurately reflects the unit rate of books per month.
