Joey received a report that he scored in the 98th percentile on a national standarized reading test but in the 78th percentile on the math portion of the test. explain to joey's grandmother, who knows no statistics, what these numbers mean. answers: a. joey scored worse than 2% of all students who took the reading test and he scored as well as or better than 78% of all students who took the math test. b. joey scored worse than 98% of all students who took the reading test and he scored as well as or better than 22% of all students who took the math test. c. joey scored worse than 2% of all students who took the reading test and he scored as well as or better than 22% of all students who took the math test. d. joey scored worse than 98% of all students who took the reading test and he scored as well as or better than 78% of all students who took the math test.

A given score in a given percentile means that percentage of scores was below the given score. The appropriate choice is ...

... A. Joey scored worse than 2% of all students who took the reading test and he scored as well as or better than 78% of all students who took the math test

answer: 177/8

step-by-step explanation:

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
