The correct answer is C 126 miles
I'm pretty sure he saved $27. I just divided 90 by 20 to get the amount of times he would have saved 6 dollars. Then, I multiplied that number, 4.5, times 6 to get the amount he saved. Hope that helps (and that it's correct lol). <span />
Hello
A residual<span> is the difference between the observed y-value (from </span>scatter plot<span>) and the predicted y-value (from regression </span>equation<span> line). It is the vertical distance from the actual </span>plotted<span> point to the point on the regression line.

Answer:
Step-by-step explanation:
x is the number of GB
f(x) is the cost in dollars
f(x) = 10x
Bill for 6 GB = f(6) = 60
:::::
f(x) = 8x+15
Bill for 8 GB = f(10) = 95
:::::
f(x) = 5x+30
Bill for 2 GB = f(2) = 40
