Tommy wants to analyze the weight of the students at his school. He measures the weight of 100 randomly selected students in the school. He finds the mean is 80 pounds and the standard of the deviation is 8 pounds. Out of 100 students , how many should weigh between 64 and 96 pounds ?

4+n=5

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

answer: 8

step-by-step explanation:

1332.

this is because to get from 333 to 999 you multiply by 3, and you should do the same to the number of hours.

therefore you would do 444*3=1332
