Answer:





The plot is on the figure attached. And we can see that the residuals shows a curved pattern so then the best conclusion for this case would be:
Yes, the points are in a curved pattern.
Step-by-step explanation:
The correct formula for the residuals is given by:

Who represent the observed value minus the predicted. We can find the individual residuals and we got:





The plot is on the figure attached. And we can see that the residuals shows a curved pattern so then the best conclusion for this case would be:
Yes, the points are in a curved pattern.
Answer:
x = 9
Step-by-step explanation:
You have to use the Secant Segment theorem:
AB * AC = AD * AE
This means that the external piece of the secant times the whole secant for one is equal to the external piece of the secant times the whole secant for the other.
Now, setup an equation:
8(x + 8) = 4(30 + 4)
Simplify:
8x + 64 = 120 + 16
8x = 72
x = 9
