What is the mean score for Jill's quizzes? (Round to the nearest hundredth)

Answer 1

Answer:

3.08

Step-by-step explanation:

Take the points earned times the number of quizzes with that score to get the total number of points earned

0*0 + 1*1+2*3 + 3*4 +4*4 +5*1 =

0+1+6+12+16+5

40

Now how many quizzes were there?

1+3+4+4+1 = 13

Take the total points divided by the number of quizzes to get the mean

40/13 =3.076923077

Round to the nearest hundredth

3.08

Answer 2

Answer:

40/13 or 3.08

Step-by-step explanation:

Sum(f × x) ÷ sum(f)

[(0×0) + (1×1) + (3×2) + (4×3) + (4×4) + (1×5)] ÷ (0+1+3+4+4+1)

40/13 or 3.076923077
