Answer:
The standard deviation of this distribution is 0.8850.
Step-by-step explanation:
For each U.S. mortgage in the sample, there are only two possible outcomes. Either it is delinquent, or it is not. The probabilities of each mortgages being delinquent are independent from one another. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The standard deviation of the binomial distribution is:

11% of U.S. mortgages were delinquent last year.
This means that 
A random sample of eight mortgages was selected. What is standard deviation of this distribution?
This is
when 

The standard deviation of this distribution is 0.8850.
Answer:
TS = 22
x = 49
Step-by-step explanation:
(5x-2)/39 = (3x+1)/26
Multiply both sides by 78:
10x-4 = 9x+3
x=7
3x+1 = 22
:::::
(x+5)/36 = 30/20
x+5 = 54
x = 49
Answer: Quadrant 1 (northeast quadrant)
=================================================
Explanation:
Add on 360 degrees to do a full rotation
-302+360 = 58
So angles -302 degrees and 58 degrees are pointing in the same direction. These angles are in quadrant 1, which is the northeast quadrant
Note: because the angles -302 and 58 point in the same direction, we consider these angles to be coterminal.
You should’ve put a picture to make it easier for us
