C/2 welp is that your answer ?
Answer:
8.0372
Step-by-step explanation:
given that an instructor computed a least squares regression line to predict final course percentage based on Exam 1.
The regression equation was found out as

When a student makes a grade of 76 one exam 1, and 71.66% in final exam we have

Substitute to get the estimated y as per regression line as

Residual = difference between y hat and y
= 
(x+6)(x+2)
Simplifying
(x + 6)(x + 2)
Reorder the terms:
(6 + x)(x + 2)
Reorder the terms:
(6 + x)(2 + x)
Multiply (6 + x) * (2 + x)
(6(2 + x) + x(2 + x))
((2 * 6 + x * 6) + x(2 + x))
((12 + 6x) + x(2 + x))
(12 + 6x + (2 * x + x * x))
(12 + 6x + (2x + x2))
Combine like terms: 6x + 2x = 8x
(12 + 8x + x2)
