Answer:
Reliability= 149.94
Step-by-step explanation:
Field data have indicated that Unit A has a failure rate of 0.0004 failure per hour.
Reliability per hour=1- failure rate
Reliability per hour= 1-0.0004
Reliability per hour= 0.9996
Reliability= rate if reliability * number of hours
Rate of reliability= 0.9996 per hour
Number of hours= 150 hours
Reliability= 0.9996*150
Reliability= 149.94
I'm assuming 6(8) is 6^8, and none of the other answers are correct, so the answer is 6(8). This is because you are not multiplying 6 by 8, you are multiplying 6 by 6, but you're doing it 8 times. For example 6 × 6 = 36, 36 × 6 = 216, etc. I hope this helps!
