There are 5 red marbles, 4 blue marbles and 7 black marbles in a bag. Like the theoretical P(choosing a red)

Step-by-step explanation:

1. To find the answer, add up all the marbles.

4+5+7= 16

2. Because 16 is the total number of outcomes, it will be the denominator.

3. Because 5 is the number of desireable outcomes, it will be the numerator.

(Note: the decimal equivalence is 0.3125).

(Note: the ratio equivalence is 5:16).

(Note: the percent equivalence is 31.25%).

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! : )
