Answer:

Option D. -0.901

Step-by-step explanation:

we know that

<u>The correlation coefficient</u> r measures the strength and direction of a linear relationship between two variables. The value of r is always between +1 and –1

Using a Excel tool (Correl function)

The value of coefficient r is -0.9006876

Round to three decimal places

r=-0.901

see the table attached

The corresponding angle to angle 1 is angle 11.

<h3>How to depict the angles?</h3>

It should be noted that corresponding angles are the angles that occupy the same relative position at each intersection.

The alternate exterior angle to 12 is angle 4.

The alternate interior angle to angle 6 will be angle 9.

The vertical angle to angle 4 is angle 2. They are angles that are opposite each other when two lines cross.
