They increase through the day.
11 - Noon - most, 15 bags1 - 2 - least, 0 bags
See graph above. Time is independent so it goes on the x-axis.
135
a. It tells how many jumping jacks she did each 10 second interval.b. It doesn't give a total number completed.c. She did 135 jumping jacks.
No, Ken did 72 and Andrea did 110.
The scales are different; Andrea’s scale counts by 20’s and Ken’s count by 10’s.
18) A19) a. 2/6 or 1/3
b. Your probability of winning increases each time you add another winner block if you have only one winner block your probability of winning is 1/5. however, if you have 6 winner blocks (10 blocks total), your probability of winning is 3/5.

Graphs
What do you think? 1)What are the variables for this
graph?
2)Which variable goes on the x-axis?
3)Which Variable goes on the y-axis?
4)What happens between 3.5 and 4.5 hours?
5)How is this interval show on the graph?
6)Do you think they got tired as the day progressed?

The group traveled 45 miles in 5 hours.
They went the farthest from 0 - 0.5, and the least from 3.5 - 4.5.
They went farther the first half, 27 miles.
I think a table because…

I think a graph because…
What did you learn?
1)Which variable is displayed on the x-axis? 2)What is the least value on the X-axis?
What is the greatest value on the x-axis?
3) Why is it reasonable to have the size of the intervals for the x-axsis be 0.5 hours? 4) Which variable is displayed on the y-axis?
5) What is the least value on the y-axis? What is the greatest value on the y- axis?
6) What is the size of the interval for the y-axis?
7) Did anyone use an interval other than 5 miles for the y-axis?
