Me. find the coordinate of b' after a 180° rotation of the triangle about the origin. a. (1,2)b. (3,5)c. (3,-5)d. (-3,-5)

  b. (3, 5)

Step-by-step explanation:

Rotation by 180° multiplies each coordinate by -1.

  B' = -1×B = -(-3, -5) = (3, 5)

answer: .64

step-by-step explanation

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