Answer:
I mean it kind of speaks for itself
Step-by-step explanation:
8 divided by 1/5 is the same thing as 8 multiplied by 5
Use pythagorean theorem to find the bottom side of the left triangle.
12^2+b^2=15^2
144+b^2= 225
b^2= 81
b=9
you will then subtract 9 from 25 to get 16
area from the triangle on the right
A=(1/2)16*12
A= 96 in^2
then for the triangle on the right
A= (1/2)12*9
A= 54 in^2
then add the two areas together
Total Area= 150 in^2
Answer for your question is on the picture below
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

base = 5
height = 4
hypotenuse = sqrt ( 5^2 +4^2) = sqrt(25+16) = sqrt(41)
5+4 = 9
so perimeter = 9+ sqrt(41)
answer is the 3rd one.
