Given here is the joint probability function associated with data obtained in a study of automobile accidents in which a child (under age 5 years) was in the car and at least one fatality occured. specifically, the study focused on whether or not the child survived and what type of seatbelt (if any) he or she used. define

y1 = { 0, if the child survived, 1, if not,
and
y2 = { 0 if no belt used, 1 if adult belt used, and 2 if car seat belt used

notice that y1 is the number of fatalities per child and, since children's car seats usually utilize two belts, y2 is the number of seat belts in use at the time of accident.

given:

y1
y2 0 1 total
0 0.38 0.17 0.55
1 0.14 0.02 0.16
2 0.24 0.05 0.29
0.76 0.24 1

what is your interpretation of this value?

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.
