Which measure BEST shows the center of this data set?

10

step-by-step explanation:

7+3=10

step-by-step explanation:

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

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)
