Bentley earned a score of 52 on Exam A that had mean of 74 and a standard deviation of 20. He is about to take Exam B that has a mean of 300 and a standard
deviation of 20. How well must Bentley score on Exam B in order to do equivalently
well as he did on Exam A? Assume that scores on each exam are normally distributed.

That they are numbers and related to each other.

72 is the mode because it shows up the most number of times

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
