Probability of white marble = 3/ 25 = 0.12
Answer: The right option that represents possible inputs and outputs of the function is the ordered pair
{(-2, -18), (2, 14), (0, -2)}
Step-by-step explanation:
By crosschecking;
Y=8x-2
When x=-2 , y= 8(-2) -2 , y= -16-2, y=-18 . (-2,-18)
When x=2 , y= 8(2) -2 , y= 16-2, y= 14
(2,14)
When x=0 , y= 8(0) -2 ,y= 0-2, y= -2
(0,-2)
