Answer:

Step-by-step explanation:

$\log_ab=c\iff a^c=b\\\\Domain:\ x+2>0\to x>-2\\\\\log_3(x+2)-8=-2\qquad\text{add 8 to both sides}\\\\\log_3(x+2)=6\iff x+2=3^6\\\\x+2=729\qquad\text{subtract 2 from both sides}\\\\x=727\in D$

It would be a + because the 7 in 7y is positive, therefore it would be added to the X’s. if it was -7y, then the underline would be a –.

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 $b_{yx}=\frac{30}{10}=3$
