What is the absolute value of difference between each value and mean O 1,7,4,11,4,9,5,1
O 5.25,6.25,7.25,8.25,10.25,11.25,12. 25

1. 34

2. 268

3. x=14.4

step-by-step explanation:

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)
