According to a study done by de anza students, the height for asian adult males is normally distributed with an average of 66 inches and a standard deviation of 2.5 inches. suppose one asian adult male is randomly chosen. let x = height of the individual. a) give the distribution of x.
x ~
b) find the probability that the person is between 64 and 69 inches.
write the probability statement.

what is the probability?

  A)

B)0.6731

Step-by-step explanation:

Given : The height for Asian adult males is normally distributed with

Mean :

Standard deviation :

Let X = height of the individual.

A) The distribution of X is given by :-

B) The formula to find the z-score is given by  :-

For , x= 64

For , x= 69

Now, the required probability :-

Hence, the probability that the person is between 64 and 69 inches is 0.6731.

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e

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! : )
