Suppose the scores on all the quizzes in Mr. Jones class were normally distributed with mean 78 and a standard deviation 6

A. What percent of scores are between 78 and 93?

B. Scores greater than or equal to 90 earn an "A”. What percent of quizzes earned an "A"?

C. What percent of scores fall between 71 and 95

D. If a student had a z-score of -1.24, what was there actual score on the quiz? Show your work

yes

step-by-step explanation:

give me the question

\

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

8

step-by-step explanation:

why? because i noticed a pattern. 60 120. those numbers without the zero, make the 6 times tables leaving your answer to be b since 6 times 4 is 24 and adding a zero making it 240.
