Astudy found out that 1% of social security recipients are too young to vote. if 800 social security recipients are randomly selected, find the mean, variance and standard deviation of the number of recipients who are too young to vote

Mean :

Variance :

Standard deviation =  

Step-by-step explanation:

We know that , in Binary Distribution having parameters p (probability of getting success in each trial) and n (Total number trials) , the mean and variance is given by:-

Mean :

Variance :

We are given that ,

Total social security recipients  : n=800

The probability of social security recipients are too young to vote : p=1%= 0.01

Here success is getting social security recipients are too young to vote .

Then, the mean, variance and standard deviation of the number of recipients who are too young to vote will be :-

Mean :

Variance :

Standard deviation =  

Hence, the mean, variance and standard deviation of the number of recipients who are too young to vote :

Mean :

Variance :

Standard deviation =  

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.
