Jynessa wants to order these fractions 4/9 2/3 1/6 -2 1/2 what should she use as her common denominator

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

b). 4320 have a nice day

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)
