The value of x in the triangle is (d) 7

<h3>How to solve for x?</h3>

The complete question is in the attached image.

From the attached image of the triangle, we can see that the triangle is a right triangle, and x can be solved using the following sine function

\sin(45) = \frac{x}{7\sqrt 2}

Evaluate sin(45)

\frac 1{\sqrt 2} = \frac{x}{7\sqrt 2}

Solve for x

x = \frac{7\sqrt 2}{\sqrt 2}

Divide

x = 7

Hence, the value of x in the triangle is (d) 7

dybincka [34]

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> :

  • γ=46.6 + 0.41x

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
