Answer:

<h2>m\angleF = 34°</h2>

Step-by-step explanation:

If E and F are complementary I means that the sum of their angles add up to 90° since all complementary angles have the sum of their angles equal to 90°

To find m\angleF add m\angleE and m\angle F and equate it to 90 to find x then substitute it into the expression for m\angleF

Thats

m\angleE + m\angleF = 90

\rarr 9x - 38 + 2x + 40 = 90

\rarr 11x + 2 = 90

\rarr 11x = 90 - 2

\rarr 11x = 88

Divide both sides by 11

x = 8

Now we have

if m \angleF = 9x - 38

m\angle F = 9( 8) - 38

m\angleF = 72 - 38

We have the final answer as

<h3>m\angleF = 34°</h3>

Hope this helps you

The difference between the observed value of the dependent variable and the value predicted using the estimated regression equat
Elenna [48]

Answer:

For this case we define the dependent variable as Y and the independent variable X. We assume that we have n observations and that means the following pairs:

(x_1, y_1) ,....,(x_n,y_n)

For this case we assume that we want to find a linear regression model given by:

\hat y = \hat m x +\hat b

Where:

\hat m represent the estimated slope for the model

\hat b represent the estimated intercept for the model

And for any estimation of the dependent variable \hat y_i , i=1,...,n is given by this model.

The difference between the observed value of the dependnet variable and the value predicted using the estimated regression equation is known as residual, and the residual is given by this formula:

e_i = y_i -\hat y_i , i=1,...,n

So the best option for this case is:

d. residual
