Consider the distribution of exam scores (graded from 0 to 100) for 78 students when 35 students got an a, 25 students got a b, and 18 students got a c. complete parts (a) through (d) below. how many peaks would you expect for the distribution? a. there would probably be many peaks corresponding to the different exam scores that each student had. b. there would probably be no peaks. the distribution of grades always tends to be uniform. c. there would probably be three peaks, because even though each exam score could be anywhere between 0 and 100, the only grades received were a, b, and c. d. there would probably be one peak because there are no obvious reasons why the exam scores would form different groups.

C.There would probably be three​ peaks, because even though each exam score could be anywhere between 0 and​ 100, the only grades received were​ A, B, and C.

Step-by-step explanation:

Since, scores are indicated by grades and here students get only three grades i.e. A, B and C.

Thus, there will be only three peaks and rest points are remain constant.

Hence, option C is the only correct option i.e. There would probably be three​ peaks, because even though each exam score could be anywhere between 0 and​ 100, the only grades received were​ A, B, and C.

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

the answer is 48m^2!
