76% of U. S. adults think that political correctness is a problem in America today. You randomly select six U. S. adults and ask them whether they think that political correctness is a problem in America today. The random variable represents the number of U. S. adults who think that political correctness is a problem in America today. Answer the questions below.

--- Mean

--- Variance

--- Standard Deviation

Step-by-step explanation:

See Comment for missing details

Given

--- proportion

-- sample

Solving (a): The mean; E(x)

This is calculated as:

Substitute values for n and p

Solving (b): The variance; s^2

This is calculated as:

Substitute values for n and p

Solving (c): The standard deviation; s

This is calculated as:

Substitute value for s^2

i am sorry

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
