Julie has two formal events to go to. she has six formal dresses--two blue ones, one black, one red, and two white
given she will not wear the same dress to both events she calculates the probability of her wearing blue to both
events as
22
p(blue and blue) =
is she correct?
a)
yes, the two events are independent.
no, the two events are independent
no, the probability of the second dress being blue changes after she
chooses the first dress.
d)
yes, the probability of the second dress being blue is not dependent on the
first dress being blue.

Step-by-step explanation:

Took the test

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

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! : )
