The probability of one of three students being accepted to a program while the other two are not accepted is 3.2%, or 1.5:1, which is equivalent to a 66.7% chance.

The probability of one of three students being accepted to a program while the other two are not accepted can be calculated by dividing the total number of favorable outcomes by the total number of possible outcomes.

To calculate this, we need to know the probability of each individual student being accepted. For example, if the probability of each student being accepted is 0.2, the probability of one student being accepted while the other two are not would be (0.2)x(1-0.2)x(1-0.2), or 0.032. This would be written as a 3.2% chance.

The probability of one student being accepted while the other two are not can also be calculated using a permutation formula. The formula for this is

P(n,r) = n!/(n-r)!,

where n is the total number of students and r is the number of students accepted.

In this case, n = 3 and r = 1. So, P(3,1) = 3!/2! = 3/2 = 1.5.

This means that there is a 1.5:1 ratio of one student being accepted while the other two are not. This is equal to a 66.7% chance.

Centering x values before squaring eliminates the correlation between x and its square term, reducing multicollinearity. This helps to determine independent effects of predictor variables, and can also straighten the curve of a scatterplot.

Centering the x values before squaring is important because it helps to eliminate the correlation between the x variable and its square term. When we square a variable without centering it, we are essentially capturing the effect of both the linear and the quadratic terms.

This can lead to multicollinearity, which occurs when two or more predictor variables are highly correlated with each other.

Multicollinearity can create problems in statistical analyses because it can make it difficult to determine the independent effects of each predictor variable on the outcome variable. Centering the x values before squaring helps to reduce the effects of multicollinearity by eliminating the correlation between the x variable and its square term.

The statement "the sum of the percent frequencies for all classes in a frequency distribution will always equal" is True.

The sum of the percent frequencies for all classes in a frequency distribution will always equal 100%. This is because the percent frequency for each class is calculated by dividing the frequency of that class by the total number of observations and then multiplying by 100. Therefore, when we add up all the percent frequencies for all the classes, we get the total percentage of observations, which must be 100%.

In a frequency distribution, percent frequencies are calculated by dividing the frequency of each class by the total number of observations and then multiplying by 100.

(a) The probability that a household views television between 4 and 12 hours a day is 0.8864. (b) A household must view at least 12.63 hours of television/day to be in the top 4% of all television viewing households. (c) The probability that a household views television more than 3 hours a day is 0.9830.

(a) To find the probability that a household views television between 4 and 12 hours a day, we need to standardize the values using the formula:

z = (x - μ) / σ

where x is the value we want to find the probability for, μ is the mean, and σ is the standard deviation.

For x = 4 hours:

z = (4 - 8.35) / 2.5 = -1.74

For x = 12 hours:

z = (12 - 8.35) / 2.5 = 1.46

Using a standard normal distribution table or a calculator, we can find the probabilities associated with these z-scores:

P(z < -1.74) = 0.0401

P(z < 1.46) = 0.9265

Therefore, the probability that a household views television between 4 and 12 hours a day is:

P(4 ≤ x ≤ 12) = P(z < 1.46) - P(z < -1.74) = 0.9265 - 0.0401 = 0.8864 (rounded to four decimal places).

(b) To find the number of hours of television viewing a household must have in order to be in the top 4% of all television viewing households, we need to find the z-score that corresponds to the top 4% of the normal distribution:

P(z > z*) = 0.04

Using a standard normal distribution table or a calculator, we can find that the z-score that corresponds to a probability of 0.04 is approximately 1.75.

Using the formula for z-score:

z = (x - μ) / σ

We can solve for x:

x = μ + zσ = 8.35 + 1.752.5 = 12.63 (rounded to two decimal places)

Therefore, a household must view at least 12.63 hours of television per day to be in the top 4% of all television viewing households.

(c) To find the probability that a household views television more than 3 hours a day, we can standardize the value of x = 3 using the formula for z-score:

z = (x - μ) / σ = (3 - 8.35) / 2.5 = -2.14

Using a standard normal distribution table or a calculator, we can find the probability associated with this z-score:

P(z > -2.14) = 0.9830 (rounded to four decimal places).

Therefore, the probability that a household views television more than 3 hours a day is 0.9830.

Answer:

a. 80.83 ft b. 40.42 ft

Step-by-step explanation:

Let h = height of pole = 70 ft, L = length of cable and x = distance of cable on ground to pole and Ф = angle between cable and ground.

a) How long is the cable?

Since L, h and x form a right-angled triangle with angle Ф and h being the opposite side to Ф and L being the hypotenuse side, by trigonometric ratios,

sinФ = h/L

L = h/sinФ

L = 70 ft/sin60°

L = 70 ft/0.8660

L = 80.83 ft

b) How far from the pole should the cable be attached to the ground?

Since L, h and x form a right-angled triangle with angle Ф and h being the opposite side to Ф and x being the adjacent side, by trigonometric ratios,

tanФ = h/x

x = h/tanФ

x = 70 ft/tan60°

x = 70 ft/1.7321

x = 40.42 ft

The length of the cable is 80.83 ft and the distance from the pole should the cable be attached to the ground is 40.42 ft and this can be determined by using the trigonometric function.

Given :

a) The trigonometric function can be used in order to determine the length of the cable.

\(\rm sin\theta=\dfrac{h }{L}\)

where h is the height of the pole, L is the length of the pole, and \(\theta\) is the angle from the ground.

Substitute the known terms in the above expression.

\(\rm L=\dfrac{h }{sin\theta}\)

\(\rm L = \dfrac{70}{sin60}\)

L = 80.83 ft.

b) The trigonometric function can be used in order to determine the distance from the pole should the cable be attached to the ground.

\(\rm tan \alpha =\dfrac{h}{x}\)

The standard deviation of the given data can be calculated using the formula for the population standard deviation:

Standard deviation = √[∑(X - μ)² * f / N]

where X is the data value, μ is the mean, f is the frequency, and N is the total number of observations.

Given the data:

X: 3 4 5 6 7 8 9

f: 37 8 10 12 4 3 2

Assumed mean (μ) = 6

To calculate the standard deviation, we need to calculate the squared difference between each data value and the mean, multiply it by the frequency, and sum up these values. Then divide the sum by the total number of observations (N) and take the square root of the result.

Let's calculate it step by step:

(X - μ)² * f:

(3 - 6)² * 37 = 111

(4 - 6)² * 8 = 32

(5 - 6)² * 10 = 10

(6 - 6)² * 12 = 0

(7 - 6)² * 4 = 4

(8 - 6)² * 3 = 12

(9 - 6)² * 2 = 18

Sum of (X - μ)² * f = 187

Now divide the sum by the total number of observations (N = 37 + 8 + 10 + 12 + 4 + 3 + 2 = 76) and take the square root of the result:

Standard deviation = √(187 / 76) ≈ 1.82

Therefore, the standard deviation of the given data is approximately 1.82.

The vector field f(x,y) = 33x^2y^2i + 22x^3yj is conservative, and its potential function is φ(x,y) = 11x^3y^2 + 11x^2y^2 + C.

To determine if a vector field is conservative, we need to check if it is the gradient of a scalar function (i.e., a potential function). We can do this by taking the partial derivatives of each component with respect to their respective variables and checking if they are equal:

∂f_x/∂y = 66xy^2
∂f_y/∂x = 66xy^2

Since these partial derivatives are equal, the vector field is conservative. We can then find a potential function by integrating each component with respect to their respective variable:

φ(x,y) = 11x^3y^2 + 11x^2y^2 + C

where C is the constant of integration.

Therefore, the vector field f(x,y) = 33x^2y^2i + 22x^3yj is conservative, and its potential function is φ(x,y) = 11x^3y^2 + 11x^2y^2 + C.
