9. Example 1

10. Example 2
1/5 x 1/5 = 1/25

11. You Try!
½ x 1/6 = 1/12

12. Example 3
2/16 x 6/16 = 1/8 x 3/8 = 3/64

13. You Try
1/8

14. You Try!
Given: Variable x is Grade Level. Variable y is hours of Homework Each Week. Task: Using the data below, construct a scatter-plot. Question: What is the relationship between these two variables? X 1 2 3 4 5 6 7 8 9 10 11 12 Y 14 15
12/20 x 11/19 = 132/380 = 33/95 (divide by 4 to reduce)
