According to a? poll, about 1717? % of adults in a country bet on professional sports. data indicates that 45.345.3? % of the adult population in this country is male. assuming that betting is independent of? gender, compute the probability that an adult from this country selected at random is a male and bets on professional sports. ? p(male and bets on professional ? sports)equals= nothing ? (type an integer or decimal rounded to four decimal places as? needed.) ? (c) using the result in part? (b), compute the probability that an adult from this country selected at random is male or bets on professional sports. ? p(male or bets on professional ? sports)equals= nothing

We are given the two probabilities:

P (bets on professional sports) = 17% = 0.17

P (adult male) = 45.3% = 0.453

-We are to find for the probability that a selected adult is male AND bets on professional sports. Since the keyword is “and” therefore this means that we have to multiply the two probabilities, that is:

P (adult male AND bets on professional sports) = P (adult male) * P (bets on professional sports)

P (adult male AND bets on professional sports) = 0.453 * 0.17

P (adult male AND bets on professional sports) = 0.07701 = 0.0770

Therefore there is a 0.0770 chance or 7.70% chance that the selected adult satisfies the above criteria.

-We are to find for the probability that a selected adult is male OR bets on professional sports. Since the keyword is “or” therefore this means that we have to add the two probabilities, that is:

P (adult male AND bets on professional sports) = P (adult male) + P (bets on professional sports)

P (adult male OR bets on professional sports) = 0.453 + 0.17

P (adult male OR bets on professional sports) = 0.6230

Therefore there is a 0.6230 chance or 62.30% chance that the selected adult satisfies the above criteria.

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! : )
