Answer:
answer a. Because 16^2=256
4^2+ 4/15^2=16.01
16.01<256 . Therefore, it is acute-angled acute
Answer: Our required probability is 0.39.
Step-by-step explanation:
Since we have given that
X be the exponentially distributed with mean life = 6 years
So, E[x]=6

So, our cumulative distribution function would be

We need to find the probability that the CPU fails within 3 years.

Hence, our required probability is 0.39.
Simplify
= 6/(gf^4)
