Tommy teacher wants to analyze the weights of the students at his school. he knows the weight of the students is normally distributed so he can use the standard normal distribution. he measures the weight of 100 randomly selected students in the school. he finds the mean is 80 pounds and the standard deviation is 8 pounds.
out of 100 students, how many should weigh between 64 and 96 pounds?

13.33%

say 50 oranges, then 100 apples

total fruit = 150

20chances out of 150 for yellow

20/150 = 13.33%

answer:

c 60% on edg

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
