11. In a recent year, about 38% of all infants born in a country were conceived through in-vitro fertilization (IVF). Of the IVF deliveries, about twenty-eight percent resulted in multiple births.

(a) Find the probability that a randomly selected infant was conceived through IVF and was part of a multiple birth.

(b) Find the probability that a randomly selected infant conceived through IVF was not part of a multiple birth.

(c) Would it be unusual for a randomly selected infant to have been conceived through IVF and to have been part of a multiple

birth? Explain.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

hope it

i believe the answer is c.

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
