Erin made a line plot of the amount of time she practiced shooting free throws each day in the past 10 days.
Airida [17]

Answer:

Data: for the 10 days of practice, we have:

0.5 hours 1 time.

0.75 hours 2 times

1 hour 3 times

1.25 hours 2 times

1.5 hours 1 time

2 hours 1 time.

A) the largest amount number of times that she practiced by the same amount of time is 3 (for the 1-hour practice)

The smallest is 1 ( for the 0.5h, 1.5h, and 2h practices)

the difference is 3 - 1 = 2.

B) the time that she practiced more times is 1 hour, she practiced that amount of time in 3 different days out of the 10 days.

C) the equation can be found by multiplying the number of hours by the number of times that she practiced that amount of time, and then adding all of them:

0.5h*1 + 0.75h*2 + 1h*3 + 1.25h*2 + 1.5h*1 + 2h*1  

D) the solution for the previous equation is 11 hours. Here the correct option is A.

Difference of a number and 17:   x - 17
eight times that = 8(x - 17)
8(x - 17) = 30

divide both sides by 8
x - 17 = 30/8

x = 30/8 + 17 which is 20.75
