An elevator has a placard stating that the maximum capacity is 2535lbs or 15 passengers. So, 15 adult male passengers can have a mean weight of up to 2535/15=169 pounds. If the elevator is loaded with 15 adult male passengers, find the probability that it is overloaded because they have a mean weight greater than 169lbs. (Assume that weights of males are normally distributed with a mean of 177lbs and a standard deviation of 29lbs.) Does this elevator appear to be safe? The probability the elevator is overloaded? Round to four decimal places as needed.

55% are girls and 45% are boys : ) hope this

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! : )
