Suppose "true-talent" average exit velocity (aev) on batted balls for all players is normally distributed with mean 86 mph and a standard deviation of 2 mph. for any sample of individual batted balls hit by one player, the standard deviation of exit velocity around a particular player's true-talent aev is 8 mph. at this point in the season, marco masher has a total of 10 batted balls with an average exit velocity of 94 mph. given only this information, the best estimate for his true talent exit velocity is closest to which whole number?

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! : )

the answer is y = 11.54

hope this : )
