Suppose x1 is a numerical variable and x2 is a dummy variable and the regression equation for a sample of n = 28 is yi=8-5x1i+2x2i. a. interpret the regression coefficient associated with variable x1. b. interpret the regression coefficient associated with variable x2.

it’s the first one your welcome

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!

the answer would be a 24

step-by-step explanation:

c=2πr=2·π·3=24
