Question

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

Line plot named as ALTDCTime Spent Practicing (hours)ALTDC shows a number line from one-fourth to two and one-fourth. The number line is divided into 8 equal parts. 1 dot on one-half, 2 dots on three-fourths, 3 dots on 1, 2 dots on one and one-fourths, 1 dot on one and half and 1 dot on 2 is given.

Part A
What is the difference between the greatest and least times Erin practiced shooting free throws?
A. 1 hour
B. 114hours
C. 112hours
D. 2 hours

Numbers may be used once, more than once, or not at all.

Part D
What is the total amount of time Erin practiced shooting free throws in the 10 days?
A. 11 hours B. 1112 hours C. 1134 hours D. 12 hours

Answer 1

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.
