The set of life spans of an appliance is normally distributed with a mean mc013-1.jpg = 48 months and a standard deviation mc013

elena55 [62]

The life span would be 24 months.

The formula for z-scores is:
$z=\frac{X-\mu}{\sigma}$

Using the information we're given we have:
$-3=\frac{X-48}{8}$

Multiply both sides by 8 to cancel it:
-3(8) = ((X-48)/8)*8
-24 = X-48

Add 48 to both sides:
-24+48 = X-48+48
24=X

Which of the following pairs of functions are inverse of each other ?

pshichka [43]

One way is to solve for the invers of the first function
remembe, to solve, replace f(x) or g(x) with y, switch x and y, solve for y and replace it with f⁻¹(x)

A.
f(x)=x/2+8
y=x/2+8
x=y/2+8
x-8=y/2
2x-16=y
f⁻¹(x)=2x-16
nope, not A

B.
f(x)=3x³+16
y=3x³+16
x=3y³+16
x-16=3y³
(x-16)/3=y³
∛((x-16)/3)=y
f⁻¹(x)=∛((x-16)/3)
nope, not the same
not B

C.
f(x)=18/x-9
y=18/x-9
x=18/y-9
x+9=18/y
y(x+9)=18
y=18/(x+9)
f⁻¹(x)=18/(x+9)
correct, the answer is C

answer is C
