The administration at Plano ISD wants to determine if a students' test scores last spring were related to the amount of time doing homework each week during remote learning. To perform this analysis, data was collected for 40 students who studied between 2 and 10 hours per week during that time period. A computer software package was used to generate the following computer output. Predictor Coef SE Coef T P
Constant 44.540 1.813 24.57 0.000
Study Time 5.5520 0.05501 10.09 0.000

What is the equation for the least squares regression line?

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
