Answer:
Scatter plot one is not a good fit so answer is first picture to the left in a top row( see the pattern). Second plot is a good fit so the answer is the last right picture in a top row( points around x axis).
Step-by-step explanation:
A random scatter of points in the residual plot indicates that the linear function is a good fit for the given data. A non random residual plot indicates that the chosen function is not a good fit.
Answer:
5(2x-8)+15=-15
10x-40+15=-15
10x-25=-15
+25 +25 (add 25 to both sides)
____________
10x=10
divide by 10 on both sides
x=1
To find how long it would take, you must divide the total amount of gallons of water in the pond by the amount of gallons drained per hour. This would translate to:

Which would give you the total amount of hours needed to completely drain the pool, aka the answer:
4290 ÷ 78 = 55
