Suppose that a researcher, using data on class size (cs) and average test scores from 105105 third-grade classes, estimates the ols regression modifyingabove testscore with caret equals 562.032 plus (negative 6.2856 )times cs comma upper r squared equals 0.10 comma ser equals 12.4testscore=562.032+(−6.2856)×cs, r2=0.10, ser=12.4. a classroom has 2020 students. the regression's prediction for that classroom's average test score is

if i put something wrong your not gonna like it so rather not say nothing.

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
