Suppose the test scores of students in a class are normally distributed with a mean of 85 and a standard deviation of 4. What is

UkoKoshka [18]

Answer:

Step-by-step explanation:

Converting it to z, we can use the formula of z-score:

z-score = $\frac{x-\mu}{\sigma}$

Where

x is the value we are checking for (here, x = 79)

$\mu$ is the mean, which is 85

$\sigma$ is the standard deviation, which is 4 now

Let's plug the information into the formula and solve for the answer:

$\frac{x-\mu}{\sigma}\\\frac{79-85}{4}\\-\frac{6}{4}\\-1.5$

B is the correct answer.

Whenever Nicole rents a movie from iTunes, the probability that it will be a comedy is 52%. Of the next seven movies she rents,

charle [14.2K]

Answer:

$(0.48)^7+(0.52)(0.48)^6+(0.52)^2(0.48)^5$

Step-by-step explanation:

Given: the probability that the movie rented by Nicole will be comedy is 52%.

To find: the probability that she rents NO MORE THAN two comedies

Solution:

Probability refers to chances of occurrence of some event.

Probability that the movie rented by Nicole will be comedy = 52% = 0.52

Probability that the movie rented by Nicole will not be comedy = 100% - 52% = 48% = 0.48

Probability that she rents NO MORE THAN two comedies = Probability that she rents no comedy movie + Probability that she rents one comedy movie + Probability that she rents two comedy movies

= $=(0.48)^7+(0.52)(0.48)^6+(0.52)^2(0.48)^5$
