The given equation is the best line that approximates the linear
relationship between the midterm score and the score in the final exam.
- AJ's residual is 0.3, which is not among the given options, therefore, the correct option is. <u>E. None of these</u>.
Reasons:
The given linear regression line equation is; = 25.5 + 0.82·
Where;
= Final exam score;
= The midterm score;
AJ score in the first test, = 90
AJ's actual score in the exam = 99
Required:
The value of AJ's residual
Solution:
By using the regression line equation, we have;
The predicted exam score, = 25.5 + 0.82 × 90 = 99.3
- The residual score = Predicted score - Actual score
∴ AJ's residual = 99.3 - 99 = 0.3
AJ's residual = 0.3
Therefore, the correct option is option E;

Answer:
x = 1
Step-by-step explanation:
Since it says quotient, that shows that 8 will be the answer of a division problem.
"4 more than x" means that it is x+4.
From there we can write out our equation: 40 / (x +4) = 8.
We want to get rid of that fraction, so we multiply by (x+4) on both sides which will result in:
40 = 8x + 32
Then, we subtract 32 from both sides:
8 = 8x
Finally, to get x, we divide 8 from both sides:
x = 1
