(a) let x be a positive real number. if 3 \leq √ < 3 + \varepsilon for all \varepsilon > 0, then x = 9.
(b) let s be a nonempty subset of the real numbers. if x is a boundary point of s, then x is an upper bound or a lower bound of the set s.
(c) the set of all rational numbers between √3 and √7 is a countable set.
(d) given any subset s of the real numbers, if its interior, int s, is nonempty, then s is an uncountable set.

okay wait before i answer, is this for your points on a graph?

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
