Suppose the scores on a test given to all juniors in a school district are normally distributed with a mean of 70 and standard deviation of 6. Find the probability that a randomly chosen junior has a score below 70

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
