Answer:
$38.06
Explanation:
Multiply $31.20 by 0.22 (22%)
Which equals 6.864
Add that to $31.20 and you get 38.064
Then you round it and get $38.06
1. No 2. Yes 3. No
I’m pretty sure
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
Simplifying: x+1=18/12
Simplify: x+1=1.5
Combine Like Terms: 1x=1.5-1
Simplify: 1x=0.5
Divide: x=0.5
