Answer 1

Answer: -1.255

Explanation:

A P E X

Answer 2

We are tasked to solve for the residual value given that when x equals 29, y will be equals to 27.255. But, when it is tested, y actual value is 26. The formula in solving residual is shown below:
Residual value = Observed value - predicted value
Residual value = 26 - 27.255
Residual values = -1.255

The answer is -1.255 for residual value.
