Answer:
This cannot factor
Step-by-step explanation:
This cannot factor because there is no number that can be factored out of all of the terms.
z=(63-84)/3= -21/7= -3
P(x>63)=p(z > -3) = .9987 or 99.87%

Answer:
D
Step-by-step explanation:
Solve x = f(y) for y.
x = ∛(y/9) -4
x +4 = ∛(y/9) . . . . . add 4
(x +4)³ = y/9 .. . . . . cube
9(x +4)³ = y . . . . . . multiply by 9
The inverse function is ...
f⁻¹(x) = 9(x +4)³ . . . . . matches the last choice
Percentage decrease = d
h1 = 2950
h2 = 2550
d/100 = (h2-h1)/h1
d/100 = (2950-2550)/2950
d=13.56
