In order to answer the question we need the lengths to do the math.
Answer:
75
Step-by-step explanation:
Homework mean x 10%: (80+100+90)/3 x 0.1 = 90 x 0.1 = 9
Quiz mean x 25%: (84+90+72)/3 x 0.25 = 20.5
Test mean x 45%: (64+72)/2 x 0.45 = 30.6
Sum of means/percentage of grade: 9 + 20.5 + 30.6 = 60.1/.8 = 75.125
