Answer:

w = -8

Step-by-step explanation:

Given:

3w + 6w - 19 = -91

Isolate w, add 19 to both sides:

3w + 6w = -91 + 19

Simplify both sides:

9w = -72

Divide both sides by 9:

w = -72/9
w = -8

A set of n = 15 pairs of X and Y scores has SSX = 10, SSY = 40, and SP = 30. What is the slope for the regression equation for p

Mumz [18]

Answer:

Step-by-step explanation:

We have given $SS_X=10$ , $SS_Y=40$ and SP =30

We have to find the slope for regression on Y from X

The slope on Y from X is given by $b_{yx}=\frac{SP}{SS_X}$

As we have given the value of SP =30 and value of $SS_X=10$

So slope for regression will be $b_{yx}=\frac{30}{10}=3$
