Answer and Step-by-step explanation:

To figure out the problem, we first need to know what supplementary means. In this question, supplementary (angles) is when two angles are next to each other, and when added together, they add up to 180 degrees.

By looking at the image, we see that angle 1 is next to angles 2 and 5.

Angles 1 and 2 don't look like they will add up to 180 degrees.

Angles 1 and <u>5</u> look like they will add up to 180 degrees.

A way to find supplementary angles is by looking at lines that go straight across, with a line intersecting the middle of the line to form the supplementary angles.

3. A set of n = 18 pairs of scores (X and Y values) has SSX = 20, SSY = 80, and SP = 10. If the mean for the X values is MX = 8
Karo-lina-s [1.5K]

Answer:

a. Pearson Correlation

r= \frac{1}{4}  or 0,25

b. The regression equation is

Y = 6+ 0,5 *X

Step-by-step explanation:

a. Pearson Correlation

Using the equation for Pearson correlation:

r = \frac{SP}{\sqrt{(SS_{x} * SS_{y})} }

r= \frac{10}{\sqrt{(20 * 80)} }

r=\frac{10}{\sqrt{1600} }

r=\frac{10}{40} =\frac{1}{4} = 0,25

b. Regression

Using regression equation

1.  Y = a+ b *X

2. a= m_{y} - b* m_{x}

3. b= \frac{SP}{SS_{x} }

So replacing first 'b' because is content in 'a' equation

b= \frac{SP}{SS_{x} }

b= \frac{10}{20}

b= \frac{1}{2} = 0,5

Knowing 'b' can know 'a' and complete the equation

a= m_{y} - b* m_{x}

a= 10 - 0,5* 8

a= 6

Replacing in the equation 1:

1.  Y = a+ b *X

Y = 6+ 0,5 *X
