Using the model equation, the predicted mean score on the final given a score of <em>10 points above the class mean</em> in the mid term exam is 50.7
<u>The Least - Square Regression equation which models the relationship between midterm and final exam score is</u> :
x = 10 points ; <u>substitute the value of x = 10 into the regression equation</u> ;
γ=46.6 + 0.41(10)
γ=46.6 + 4.1
γ = 50.7
The <em>number of points above the mean</em> he'll score in the final exam is predicted to be 50.7

Step-by-step explanation:
answer:
52
step-by-step explanation:
- we can use the 45-45-90 triangle theorem for this: x, x, x

this is because this is a square
- squares have two sides of the same length, and the diagonal is different
- the x's stand for the sides, whereas the x
stands for the diagonal
x
= 26
x = 13
- now multiply this by 4 because this is the length of one of the sides of the square. in order to find the perimeter we have to either add this four times or multiply by 4
13
X 4 = 52
I think it's the third 4 ( а² + 2а ) + 9
