A die was rolled six times. The rolls were 1, 2, 3, 3, 4, and 5. What is the mean deviation for this data? A) 3 5 B) 1 C) 2 D) 6.

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)
