Here’s how to solve:
3x-15+-9
3x-24
it looks like its constant but I could be wrong
A) the standard of error would be that all the apartment costs would have a plus/minus of $80 so therefore the data received would be inaccurate.
The equation 
has 2 and x in common. This means you can factor both the 2 and x out of the equation like so...
2x(
)
Hope this helped!

Probability of survival of one disk, p=1-0.05=0.95
If there are n drives, and failures are independent (e.g. mechanical wear and tear, and not a lightning strike or a current spike), then
Probability of survival = p^n
(a) for two disks, P(2) = 0.95^2=0.9025
(b)for three disks P(3) = 0.95^3 = 0.8574
