In 1985, the average ACT score was 18 with a standard deviation of 6. Also in 1985, the average SAT score
was 500 with a standard deviation of 100. Dr. Robertson took both tests in 1985 and scored a 26 on the ACT
and a 620 on the SAT. Which statement accurately reflects the comparison of Dr. Robertson's scores?

Which statements are true of the graph of h(x) = ^3 square root of x-4 ? check all that apply.the domain of h(x) is the set of all real numbers. the range of h(x) is the set of all real numbers. for all points (x, h( h(x) exists if and only if x – 4 0. the graph of h(x) is a translation of f(x) down 4 units. the graph of h(x) intercepts the x-axis at (4, 0).

1- 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.2- 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 the first question?
