If a normal distribution has a mean of 44 and a standard deviation of 8, what
is the z-score for a value of 46?
O A. 1.25
O B. 1.75
O c. 0.75
O
D. 0.25

The answer to this question is gotta be 0

Step-by-step explanation:

Because a normal distribution gives an area between 0 and z and the area for P(X=46) = 0

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! : )

hi! i think the answer is 1/2 : )
