Answer:
(A) It is less than the contribution predicted by the regression line.
Step-by-step explanation:
The residual is the subtraction of the observed value by the predicted value.
So, if James has a negative residual, it means that his contribution is less than what was expected by the regression line.
The correct answer is:
(A) It is less than the contribution predicted by the regression line.

Step-by-step explanation:
Answer:
y = 32.0°
Step-by-step explanation:
Using the sine ratio in the right triangle
siny° = 
= 
, hence
y = 
( ) ≈ 32.0°
Answer:
x = (-9)
Step-by-step explanation:
From the diagram, we see that the triangle is an isosceles triangle. Since it is an isosceles triangle we know that the angles at the base of an isosceles triangle are equal to each other, so the angles that is not marked will be equal to m∠2. Since now we know that, we can make the following equation...
m∠2 + m∠2 + 84 = 180
Now we solve it and get...
2(m∠2) = 180 - 84
2(m∠2) = 96
m∠2 = 48
Now we substitute m∠2 with x + 57, and get...
m∠2 = 48
x + 57 = 48
x = 48 - 57
x = (-9)
