Which of the following is not a function? a: figure1 b: figure2 c: figure3 d: figure4 explain your answer.

Figure 3

Because there are 2 arrows going to the y numbers meaning that there are multiple of an x value and in functions there can not be multiple of the same x values (if that makes any sense)

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

120 seems like the most sensible answer.

step-by-step explanation:

if there is only one topping on all caramel apples and there's 120 of them. then all apples should/will be covered in sprinkles. make sense?
