Answer:
103.75 score
Step-by-step explanation:
10 % scored higher than the mean?
50% is the mean % so we need to look for the z score corresponding to 60 % from z-score table this is z-score of .25
.25 standard deviations (which is 15) above 100 =
.25 * 15 + 100 = 103.75 score
I believe 8
Inverse property of multiplication
4. AB=4
