Geometry Choose the algebraic description that maps the image ΔABC onto ΔA′B′C′.

A.(x, y) → (x + 4,y)

B.(x, y) → (x, y + 4)

C.(x, y) → (x, y – 4)

D.(x, y) → (x – 4,y)

step-by-step explanation:

in counting the number of heads in 4 coin flips, the probability that we get exactly one head is the probability that we get anyone of the following 4 outcomes: httt, thtt, ttht, or ttth. each has probability 1/16, so the probability to get exactly one head in 4 flips is 1/16 + 1/16 + 1/16 + 1/16 = 4/16 = 1/4.
