On a test that has a normal distribution, a score of 61 falls one standard deviation below the mean, and a score of 53 falls three standard deviations below the mean. Determine the mean of this test.

f(x) is   are being squared

g(x) is   increasing by 2

h(x) is adding .25 each time

k(x) is taking the square root

f(x) and k(x) are exponential functions

i belive the biggest ratio would be 18: correct me if im wrong

answer: i think its red because you have to see what it equals to

hope that

it would be r^2 - 2rs +s^2

assuming   you mean to square it
