A survey was taken that asked participants whether or not they were happy with their job. An overall score was given. 600 of the participants were unhappy while 500 participants were happy with their job. Give a
part-to-whole fraction for comparing happy participants to the whole. Then write a part-to-whole fraction of
the unhappy participants to the whole. What percent were happy with their job and what percent were
unhappy with their job?

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?

Which statement best describes how to determine whether f(x) = x squared- x +8 is an even function ?

The price for gasoline is represented by the equation y=3.69x, where y represents the total price for x gallons of gasoline. on a graph, the number of gallons is represented on the horizontal axis, and the total price is represented on the vertical axis. determine whether each statement describes the graph of the equation. select true or false for each statement
