The Correct answer is 3

Explanation:

Using the defined function, f(a) will produce the same result when substituted for x:

F(x)=x^2-x^3

Setting this equal to 4, you can solve for a:

a2 – 5 = 4

a2 = 9

a = –3 or 3

Lily’s sister has a bag of skittles containing 3 yellow skittles, 4 red skittles, 5 green skittles, and 3 orange skittles. What

lisov135 [29]

Answer:

Read a bit so you can understand which one you want.

Percentage

15 skittles, 3 of the 15 are orange.

3 over 15, or 0.2 as a percentage.

So there is a 0.8% chance that he will NOT pick an orange skittle.

Fraction

15 skittles, 3 over 15.

3 over 15 can be 1 over 5.

So there is a 4 over 5 chance that he WONT grab an orange skittle, pretty good odds.
