The residuals for data set A and data set B were calculated and plotted on separate residual plots. If neither the residuals for data set A nor the
residuals for data set B form a pattern, what can be concluded?
A. Data set A is linear, and data set B is linear:
• B. Data set A is not linear, and data set B is not linear.
• C. Data set A is not linear, and data set B is linear.
• D. Data set A is linear, and data set B is not linear.

Suppose that a households monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hundreds of cubic feet, hcf). when graphed, the function gives a line with slope of 1.65. if the monthly cost for 13 hcf is $46.10 what is the monthly cost for 19 hcf?

Atemperature of 1.64◦f corresponds to answer in units of ◦c.
