(apex) eight people were asked if they have a brother or sister. this venn diagram shows the results. a person is randomly chosen from those shown in the venn diagram let event a = the person has a sister let event b = the person has a brother what does p(b/a) = 0.25 mean in terms of the venn diagram

The expression P(B/A) = 0.25 mean in terms of the Venn Diagram :

     Option: D

D. of the 4 people who has a sister , 1 of them has a brother.          

event A = the person has a sister

and event B = the person has a brother

This means that: A∩B denote the event that the person has a sister and brother.

Also we are given that: P(B|A)=0.25

We know that:

Also,

This means that out of the 4 person who has a sister 1 has a brother.

the answer is c just got it on ed

step-by-step explanation:

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! : )
