Answer:

z ≤ 8/21

Step-by-step explanation:

Flip the inequality sign since you are multiplying by a negative number

21z-8 ≤ 0

1.2 Divide both sides by 21

z-(8/21) ≤ 0

Add 8/21 to both sides

z ≤ 8/21

The CPU of a personal computer has a lifetime that is exponentially distributed with a mean lifetime of six years. a) What is th

amm1812

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

$\dfrac{1}{\lambda}=6\\\\\lambda=\dfrac{1}{6}$

So, our cumulative distribution function would be

$F(x)=1-e^{-\lambda x}$

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

$P(X$

Hence, our required probability is 0.39.

Find the surface area of the given prism

Wewaii [24]

Answer:

Hello! answer: 432

Step-by-step explanation:

12 × 8 = 96

12 × 6 = 72

8 × 6 = 48

Then you add them all up so...

96 + 96 + 72 + 72 + 48 + 48 = 432 therefore the surface area is 432 hope that helps!
