En una rifa participan 400 boletos numerados del 000 al 399. Si compras un boleto al azar: a) ¿Cuál es la probabilidad de que hayas comprado el boleto ganador?
b) ¿Cuál es la probabilidad de que no hayas comprado el boleto ganador?
c) Si compras 20 boletos, ¿Cuál es la probabilidad de que resultes ganador?

the reason why your question keeps getting deleted because this is not a school related question : )

i will answer your question though.

i never tried church's

m a t h w a y. c o m

step-by-step explanation:

maybe i can

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! : )
