Identify the expression for calculating the mean of a binomial distribution

Option C: np is the expression used for calculating the mean of a binomial distribution.

Explanation:

From the options, we need to determine the expression that is used for calculating the mean of a binomial distribution.

Option A: npq

The variance of the binomial distribution can be calculated using the expression npq.

Hence, Option A is not the correct answer.

Option B:

The standard deviation of the binomial distribution can be calculated using the expression

Hence, Option B is not the correct answer.

Option C: np

The mean of the binomial distribution can be calculated using the expression np

Hence, Option C is the correct answer.

Option D:

The mean of the binomial distribution cannot be determined using the expression

Hence, Option D is not the correct answer.

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
