Which pair oflines represent graphs that are perpendicular? A) y = -3x + 7 y = -3x + 2 B) y = 5x + 5 y = 10x + 5 C) 2y = 4x – 16 y = 2x – 8 D) y = 9 x = 5 E) y = x y = 3

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.
