I’m stumped on the second portion of this question. I have already solved A:

The scores of a sociology test are normally distributed, has a mean of 72.8 points and a standard deviation of 10.5 points.

A) what score is at the 65th percentile? Round to whole numbers (answer is 77 points)

B) above what score is the top 18% of the class? Round to whole numbers.

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

idk

step-by-step explanation:

soo this can be solve by using the formula:

f = p( 1 + i)^ n

where f is the future profit

p is the initial profit

i is the percent increase

n is the number of years

a . f = 30000 ( 1.05)^n

b. f = 30000 ( 1.05)^15

f = $62,368
