(08.06)The dot plot shows how many attempts it took for each student to complete a puzzle: Dot plot titled Puzzle Attempts and labeled Number of Attempts shows number line from 1 to 10. There are no dots over 1 and 10, 1 dot over 2 and 9, 2 dots over 3 and 8, 3 dots over 4 and 7, 5 dots over 5 and 6.

Is the median or the mean a better measure of center for these data and why?

A. Mean, because the data are skewed and there are outliers

B. Mean, because the data are symmetric and there are no outliers

C. Median, because the data are skewed and there are outliers

D. Median, because the data are symmetric and there are no outliers

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! : )
