Question

1. the scatter plot shows the numbers of lawns mowed by a local lawn care business during one week.

a) how many days does it take to mow 30 lawns?
b) about how many lawns can be mowed in 1 day?
c) describe the relationship shown by the data.

Explanation:

Step1: Find 30 on y - axis

Locate 30 on the "Lawns mowed" (y - axis) of the scatter - plot. Then find the corresponding x - value (days worked).

Step2: Estimate for 1 day

Look at the x = 1 value on the scatter - plot and estimate the corresponding y - value (number of lawns mowed).

Step3: Analyze data trend

Observe the overall pattern of the points on the scatter - plot to describe the relationship.

Answer:

a) Looking at the scatter - plot, when the number of lawns mowed (y) is 30, the number of days worked (x) is 4.
b) When x = 1, the number of lawns mowed (y) is about 12.
c) The data shows a positive linear relationship. As the number of days worked increases, the number of lawns mowed also increases.
