A 78% 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. Find the mean of the binomial distribution (Round to the nearest tenth as needed.)Find the variance of the binomial distribution. (Round to the nearest tenth as needed.)Find the standard deviation of the binomial distribution. (Round to the nearest tenth as needed.)Most samples of 6 adults would differ from the mean by no more than nothing. (Type integers or decimals rounded to the nearest tenth as needed.)

Step-by-step explanation:

Let x be a random variable representing the number of U.S. adults who think that political correctness is a problem in America today. Since it is a binomial probability distribution, the probability if success, p = 78/100 = 0.78

The probability of failure, q = 1 - p = 1 - 0.78 = 0.22

Number of samples = 6

Mean = np = 6 × 0.78 = 4.7

Variance = npq = 6 × 0.78 × 0.22 = 1.0

Standard deviation = √variance = 1.0

Most samples of 6 adults would differ from the mean by no more than 1

215.92 dollars is the answer

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
