CVheights= %

Answers

Answer 1
To find the coefficient of variation (CV) for each of the two data sets, we need to first calculate the standard deviation and mean for each set. Then we can use the formula:

CV = (standard deviation / mean) x 100%

For the heights data set, we have:

Mean height = (73+77+74+76+79+78+79+70+72+71+79+79) / 12 = 75.58 inches

Standard deviation of height = 3.44 inches

Using the formula above, we get:

CVheights = (3.44 / 75.58) x 100% ≈ 4.55%

For the ages data set, we have:

Mean age = (23+28+28+27+27+29+26+28+30+37+36+33) / 12 = 30.5 years

Standard deviation of age = 5.53 years

Using the formula above, we get:

CVages = (5.53 / 30.5) x 100% ≈ 18.13%

Comparing the results, we see that the coefficient of variation for heights is much smaller than that for ages. This suggests that the heights of the pitchers are more tightly clustered around the mean than their ages. In other words, the heights of the pitchers are less variable than their ages.

Answers

The reflection line  that maps polygon ABCDE to polygon A' B' C' D' E' is the y-axis.

What do you mean by reflective line?

The image is reflected through a line known as a reflection line. A pattern is said to mirror another pattern, and then every point in the pattern is equidistant from every corresponding point in the other pattern. The reflected image must be the same shape and size, but the image is in the opposite direction.

In order to determine the line of reflection that maps  polygon ABCDE to polygon A' B' C' D' E', we must find a symmetrical line  equidistant from each corresponding pair of points. If you project the image across the x-axis, vertex A (-1, -4) is mapped to A' (13, -4) and vertex E (1, -6) is mapped to E'. (11, 6). Therefore, the reflection line must be the x-axis.

If we map the image to the cross x=6, vertex A (-1, -4) would correspond to A' (13, -4) and vertex E (1, -6) would correspond to E' (3, 6). ). Therefore, the reflection line cannot be x=6.

If we project the pattern perpendicular to y=-3, the point A (-1, -4) is opposite to the point A' (-7, -4) and the vertex E (1, -6)  to  the point E . (7, 6). Therefore, the reflection line  cannot be y=-3.

 If you project the image across the y-axis, point A (-1, -4) is mapped to point A' (-13, -4) and  vertex E (1, -6) is mapped to E. (-11 , 6). Therefore, the reflection line  must be the y-axis.

 Therefore, the reflection line  that maps  polygon ABCDE to polygon A' B' C' D' E' is the y-axis.

How to obtain probabilities using the normal distribution?

The z-score of a measure X of a normally distributed variable that has mean represented by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is obtained by the equation presented as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The z-score represents how many standard deviations the measure X is above or below the mean of the distribution of the data-set, depending if the obtained z-score is positive(above the mean) or negative(below the mean).The z-score table is used to obtain the p-value of the z-score, and it represents the percentile of the measure X in the distribution.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation given by the equation presented as follows: [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

The parameters for this problem are given as follows:

[tex]\mu = 25, \sigma = 1.3, n = 68, s = \frac{1.3}{\sqrt{68}} = 0.1576[/tex]

The probability of a score less than 25.3 is the p-value of Z when X = 25.3, hence:

Solve: 2 sin ϕ cos ϕ + 2 sin ϕ + cos ϕ + 1 = 0 for 0 < ϕ < 2π

Answers

Answer:

We can start by using the identity 2 sin ϕ cos ϕ = sin 2ϕ to simplify the left-hand side of the equation:

2 sin ϕ cos ϕ + 2 sin ϕ + cos ϕ + 1 = sin 2ϕ + 2 sin ϕ + cos ϕ + 1

Next, we can use another identity, sin^2 ϕ + cos^2 ϕ = 1, to eliminate the cosine term:

sin 2ϕ + 2 sin ϕ + cos ϕ + 1 = sin 2ϕ + 2 sin ϕ + √(1 - sin^2 ϕ) + 1

Now, we can substitute u = sin ϕ to obtain a quadratic equation in u:

sin 2ϕ + 2 sin ϕ + √(1 - sin^2 ϕ) + 1 = sin^2 ϕ + 2 sin ϕ + √(1 - sin^2 ϕ) + 1

sin 2ϕ = sin^2 ϕ

2 sin ϕ cos ϕ = sin^2 ϕ - cos^2 ϕ

2 u √(1 - u^2) = u^2 - (1 - u^2)

2 u √(1 - u^2) = 2 u^2 - 1

4 u^2 (1 - u^2) = (2 u^2 - 1)^2

4 u^4 - 4 u^2 + 1 = 0

This is a quadratic equation in u^2, which can be solved using the quadratic formula:

u^2 = [4 ± √(16 - 16)] / 8 = 1/2 or u^2 = 1

Since 0 < ϕ < 2π, we have 0 < u < 1, so u^2 = 1/2. Therefore, sin ϕ = u = ±√(1/2) and cos ϕ = ±√(1 - u^2) = ±√(1/2).

We can summarize the solutions as follows:

sin ϕ = √(1/2) or sin ϕ = -√(1/2)

cos ϕ = √(1/2) or cos ϕ = -√(1/2)

Therefore

Suppose the probability that an adult watches the news at least once per week is 0.60. We randomly survey 8 people. Let X = the number that watch the news at least once per week. Find the probability that at least 6 adults watch the news.

Answers

The answer of the given question based on the probability is , the probability that at least 6 adults watch the news is approximately 0.755.

What is Probability?

Probability is  measure of likelihood or chance of  event occurring. It is a number between 0 and 1, where 0 indicates that an event is impossible and 1 indicates that an event is certain. Probability is used to analyze random experiments and events, and it is an essential concept in statistics, mathematics, and many other fields.

This is a binomial probability problem, where X follows a binomial distribution with n = 8 and p = 0.60. We want to find the probability that at least 6 adults watch the news, which can be written as:

P(X ≥ 6) = P(X = 6) + P(X = 7) + P(X = 8) + ...

To solve , we use  binomial probability formula:

P(X = k) =(n choose k) *p^k *(1 - p)^(n - k)

where "n choose k" is the binomial coefficient, which represents the number of ways to choose k items from a set of n items.

Using this formula, we can find the probabilities for each value of k:

P(X = 6) = (8 choose 6) * 0.60⁶ * 0.40² = 0.311

P(X = 7) = (8 choose 7) * 0.60⁷ * 0.40¹ = 0.276

P(X = 8) = (8 choose 8) * 0.60⁸ * 0.40⁰ = 0.168

Note that we can also use  binomial probability table or  calculator with  binomial probability function to find the probabilities.

Then, we can add these probabilities to get the probability that at least 6 adults watch the news:

P(X ≥ 6) = P(X = 6) + P(X = 7) + P(X = 8) + ... = 0.311 + 0.276 + 0.168 + ...

This is a infinite series, but we can stop at P(X = 8) since the probabilities become very small after that.

P(X ≥ 6) = 0.755

Therefore, the probability that at least 6 adults watch the news is approximately 0.755.

The average velocity is given by the displacement during the time thus,[3, 4]: Average Velocity = 40 m/s. [3, 3.5]: Average Velocity = 40 m/s. [3, 3.1]: Average Velocity = 40 m/s. [3,3.01]: Average Velocity = 40 m/s.

What is speed and velocity?

Unaffected by direction, speed is a scalar quantity that describes how quickly an object is travelling. The speed and direction of an object's motion are both described by its velocity, which is a vector quantity. In other terms, velocity is the rate of positional change of an object in a specific direction. Therefore, if two objects are travelling in separate directions or if one is accelerating while the other is not, they can have the same speed but distinct velocities.

The average velocity is given by the displacement during the time, thus we have:

Displacement = h(t2) - h(t1) = (40t2 - 0.8312) - (40t1 - 0.8312) = 40(t2 - t1)

Now, the average velocity between t2 - t1 is:

Average Velocity = Displacement / Duration = 40(t2 - t1) / (t2 - t1) = 40 m/s

Using the different values of t2 and t1 we see that:

[3, 4]:

Average Velocity = 40 m/s

Average Velocity = 40 m/s

The number of dahlias should the florist expect to sell on a day with 120 customers is 90 bouquets.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.

We are given that;

Sold bouquets=15

Total customers=120

Now,

In this case, the number of successful outcomes is 15, and the number of total outcomes is 20.

So the experimental probability is:

2015​=43​

To find the expected number of bouquets of dahlias to sell on a day with 120 customers, you need to multiply the experimental probability by the number of customers.

In this case, you need to multiply 3/4 by 120:

3/4​×120=3×120​/4

=360/4​

=90

Therefore, by the unitary method the answer will be 90 bouquets

The equation of the circle in standard form with a center at (-6, 5) and passing through the point (-11, 3) is (x + 6)² + (y - 5)² = 29.

What is the equation of the circle?

The equation of a circle in standard form with a center at (h, k) and a radius r is:

(x - h)² + (y - k)² = r²

Center: (h, k) = (-6, 5)

Point on circle: (-11, 3)

Substituting these values into the standard form equation:

(x - (-6))² + (y - 5)² = r²

(x + 6)² + (y - 5)² = r²

Now we need to find the value of r, which is the radius of the circle.

The distance between the center (-6, 5) and the point (-11, 3) is equal to the radius of the circle.

Using the distance formula:

r = √((x₂ - x₁)² + (y₂ - y₁)²)

r = √((-11 - (-6))² + (3 - 5)²)

r = √((-5)² + (-2)²)

r = √(25 + 4)

Fred, a frequent business traveler, is considering signing up for a hotel rewards program.
Hotel Elegance is currently offering 881 points for signing up, plus 22 points for every night
Fred books at the hotel. Alternatively, Hotel Paradiso is offering a sign-up bonus of 851
points, plus 23 points per night. If Fred books a certain number of nights, the points he earns
with either hotel will be the same. How many points will he have? How many nights will that
be?

Answers

If Fred books a certain number of nights, If Fred books 30 nights at either hotel, he will earn 1,661 points.

What are the points?

Let's assume that Fred books "n" nights at the hotel.

For Hotel Elegance, the total number of points that Fred will earn is:

881 + 22n

For Hotel Paradiso, the total number of points that Fred will earn is:

851 + 23n

According to the problem, Fred will earn the same number of points at both hotels if:

881 + 22n = 851 + 23n

Solving for "n", we get:

n = 30

Therefore, if Fred books 30 nights at either hotel, he will earn the same number of points. To find out how many points he will earn, we can substitute "n=30" into either equation:

For Hotel Elegance:

881 + 22n = 881 + 22(30) = 1,661 points

For Hotel Paradiso:

851 + 23n = 851 + 23(30) = 1,621 points

Therefore, if Fred books 30 nights at either hotel, he will earn 1,661 points.

What is triangle?

A triangle is a closed, two-dimensional geometric shape that is formed by three line segments, called sides, that intersect at three points, called vertices. Triangles are one of the most basic shapes in geometry and are studied extensively in mathematics. The properties of triangles depend on the length of their sides and the size of their angles. Triangles can be classified based on the length of their sides as equilateral, isosceles, or scalene, and based on the size of their angles as acute, right, or obtuse. In an equilateral triangle, all three sides are of equal length. In an isosceles triangle, two sides are of equal length, while the third side is of a different length. In a scalene triangle, all three sides are of different lengths.

Here,

Since WXYZ is a kite, we know that its diagonals, WY and XZ, intersect at a right angle and bisect each other. Let M be the point of intersection of the diagonals, so that MW = MY and MX = MZ.

We can use the Pythagorean theorem to find MW and MX, and then use the fact that they are equal to find WZ.

Using the Pythagorean theorem in right triangles WMX and WMY, we have:

MW² = WX² - MX²

= 17² - 5²

= 264

MY² = WY² - MW²

= 13² - 264

= 25

MX² = XZ² - MZ²

= 17² - 13²

= 144

Since MW = MY, we have MW = √(25)

= 5

Therefore, WZ = 2MX

= 2√(144)

= 2*12

= 24

number is.
b.|-109|
c.|-7|-2=
a.
b.
109
-109
C. -9

Answers

a. The absolute value of a number is the distance of the number from zero on a number line. It is always a non-negative value, meaning that it is either zero or a positive number. It is denoted by two vertical bars surrounding the number, like |x|.

b. The absolute value of -109 is the distance of -109 from zero on a number line. Since -109 is 109 units away from zero, the absolute value of -109 is 109. Therefore, |-109| = 109.

c. First, we need to evaluate |-7|, which is the absolute value of -7. The distance of -7 from zero on a number line is 7 units, so |-7| = 7. Therefore, the expression |-7| - 2 is equivalent to 7 - 2, which is equal to 5. Therefore, |-7| - 2 = 5.

We have a total of 10 columns and 10 rows.

Total boxes = 10×10 ⇒ 100

Number of shaded boxes = 3×10 ⇒ 30

Each box contains X's out of 100 that is:

              = 30/100

                 = 0.30

We can represent a number of columns in decimal such that:

            = 20/100  = 0.20

The expression becomes 0.20×0.30.

Thus, the expression 0.20×0.30 could be modeled by the given decimal grid option (A) is correct.

Assume the random variable X has a binomial distribution with the given probability of obtaining a success. Find the following probability, given the number of trials and
the probability of obtaining a success. Round your answer to four decimal places.
P(X ≤ 3).n = 7, p = 0.4

Answers

The probability of success for given number of trials is 0.4751.

What is probability?

Probability can be used to determine the likelihood of an event. The likelihood that an event will happen is the only useful outcome. a scale where 0 indicates impossibility and 1 indicates a specific occurrence.

We know that the probability is given by:

P = nCx * [tex]p^{x}[/tex] * [tex]q^{n-x}[/tex]

P (x ≤ 3) = P(0) + P(1) + P(2) + P(3)

Now,

⇒ P(0) = 7C0 * [tex]0.4^{0}[/tex] * [tex]0.6^{7}[/tex]

⇒ P(0) = 1 * 1 * 0.0279936

⇒ P(0) = 0.02799

Similarly,

⇒ P(1) = 7C1 * [tex]0.4^{1}[/tex] * [tex]0.6^{6}[/tex]

⇒ P(1) = 7 * 0.4 * 0.046656

⇒ P(1) = 0.13064

Similarly,

⇒ P(2) = 7C2 * [tex]0.4^{2}[/tex] * [tex]0.6^{5}[/tex]

⇒ P(2) = 21 * 0.16 * 0.07776

⇒ P(2) = 0.02613

Similarly,

⇒ P(3) = 7C3 * [tex]0.4^{3}[/tex] * [tex]0.6^{4}[/tex]

⇒ P(3) = 35 * 0.064 * 0.1296

⇒ P(3) = 0.2903

So, now we get

⇒ P (x ≤ 3) = P(0) + P(1) + P(2) + P(3)

⇒ P (x ≤ 3) = 0.02799 + 0.13064 + 0.02613 + 0.2903

⇒ P (x ≤ 3) = 0.4751

Hence, the probability of success for given number of trials is 0.4751.

A family has two cars. The first car has a fuel efficiency of 35 miles per gallon of gas and the second has a fuel efficiency of 40 miles per gallon of gas. During
one particular week, the two cars went a combined total of 1725 miles, for a total gas consumption of 45 gallons. How many gallons were consumed by each of
the two cars that week?
First car: gallons
Second car: gallons

Answers

The first car consumed 15 gallons of gas

The second car consumed 30 gallons of gas during the week

To solve this problem

Let's denote the number of gallons consumed by the first car as x, and the number of gallons consumed by the second car as y.

We know that the total gas consumption is 45 gallons, so:

x + y = 45

We also know that the total distance traveled is 1725 miles, and that the fuel efficiency (miles per gallon) of the first car is 35, and of the second car is 40. Using this information, we can write another equation:

35x + 40y = 1725

We now have two equations with two unknowns, which we can solve simultaneously to find x and y.

Multiplying the first equation by 35, we get:

35x + 35y = 1575

Subtracting this equation from the second equation, we get:

5y = 150

y = 30

Substituting y = 30 into the first equation, we get:

x + 30 = 45

x = 15

Therefore, the first car consumed 15 gallons of gas, and the second car consumed 30 gallons of gas during the week.
