Assume that the numbers of a data set are arranged in ascending order. Which statement about the third quartile is true? A. All of the numbers lie below the third quartile. B. All of the numbers lie above the third quartile. C. 50% of the numbers lie below or on the third quartile, and the remaining 50% lie above it. D. 25% of the numbers lie below or on the third quartile, and the remaining 75% lie above it. E. 75% of the numbers lie below or on the third quartile, and the remaining 25% lie on or above it.

The equation respenting the left table is

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
