In order to calculate P (-1.5 ≤ z ≤ 0.5) using tables where z is a value from the standard normal distribution, which of the following expressions could be used? Group of answer choices
P (z ≤ 0.5) - P (z ≤ -1.5)
P (z ≤ -1.5) + P (z ≤ 0.5)
P (z ≥ -1.5) × P (z ≤ 0.5)
4 × P (z ≤ -1.5)
P (z ≤ -1.5) - P (z ≤ 0.5)

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

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! : )
