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.

Make t as the subject!! HELP MEE
Umnica [9.8K]

Answer:

t = (p^2/mn) - 1/n

Step-by-step explanation:

Here, we want to make t the subject of the formula

we start by equating both sides so as to remove the root

we have this as;

m(t + n)/t = p^2

m(t + n) = tp^2

mt + mn = tp^2

mn = tp^2 - mt

mn = t(p^2-m)

t = (p^2 - m)/mn

t = p^2/mn - 1/n

A bird at the top of a tree looks down at a field mouse with an angle of depression of 65°. If the field mouse is 30 meters from
Nesterboy [21]
The angle of depression made by the bird to the mouse is seen on the attached image. We can find the distance from the field mouse up to the bird's eye by getting the hypotenuse of the triangle formed. Using the CAH in Pythagorean Theorem, we will have:

cos ∅ = adjacent / hypotenuse
cos 65 = 30 / h
h = 70.98 ≈ 71 m  ⇒ the answer is D
