Question

The scatter plot below can be used to find the approximate rate at which water flows through a garden hose. The line of best fit for the scatter plot can be described by the equation y = 4/5x. If the rate, in gallons per minute, continues, approximately how many gallons of water will flow from the hose in 45 minutes?

36
39
56
24

Answer 1

`36\ \text{gallons per unit}` will flow from the hose in 45 minutes.

Explanation:

The line of best fit for the scatter plot can be described by the equation :

`y=(4)/(5)x`

y is amount of water in gallons

x is time

When x = 45 minutes, put x = 45 in above formula as :

`y=(4)/(5)* 45\\\\y=36\ \text{gallons per unit}`

So,
`36\ \text{gallons per unit}` will flow from the hose in 45 minutes.
