a) If a student is selected at random, find the probability the student has a blue card and the student is a sophomore.
b) If a student is selected at random, find the probability that the student has a red card given that the student is a freshman.
c) If a student is selected at random, find the probability that the student is a freshman given that the student has a blue card.
d) If a student is selected at random, find the probability that the student is a freshman or the student has a blue card.

astronomers is your final answer! : )

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! : )

no because after the troops were pulled many blacks were killed by hangings lynchings and other cruel ways which in a way interrupted the reconstruction of the south and differed from the way abraham lincoln had an idea of reconstruction

just keep asking questions until you have a better understanding.
