Which simulation would NOT generate a random sample representative of the population from which it was selected? A. using a random number generator to generate an identification number for the winner of the school door prize each week throught out the school year.

B. spinning a spinner with 3 equally divided section to determine students favorite day of the week.

C. using a computer model to select 3 students to represent the school on the float in the town parade

D. selecting students names out of a bag to serve on the school macot committee.

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! : )

27 + 13x + 15 = (x + 5)( =

step-by-step explanation:

27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( = 27 + 13x + 15 = (x + 5)( =

he has 140 chickens because he has 10 times more chickens than ducks and he has 14 ducks so 14*10=140
