Answer:
36 gallons
Explanation:
The dirty work has been done for you; the equation of the regression line is approx. y = (4/5)x.
You can estimate the amount of water flowing from a hose using this equation.
Over the period [0, 45] (minutes), the amount of water that will flow is
y = (4/5 gallon / minute)(45 minutes) = 36 gallons
