Answer:
The approximate value of the area is
Step-by-step explanation:
we know that
The area of the circle (landing pad) is equal to
we have
substitute
----> exact value of the area
Find the approximate value
assume
------> approximate value of the area
The probability that the transistor will last between 12 and 24 weeks is 0.424
X= lifetime of the transistor in weeks E(X)= 24 weeks
O,= 12 weeks
The anticipated value, variance, and distribution of the random variable X were all provided to us. Finding the parameters alpha and beta is necessary before we can discover the solutions to the difficulties.
X~gamma()
E(X)=
=
=6 weeks
V(x)=
=24/6= 4
Now we can find the solutions:
The excel formula used to create Figure one is as follows:
=gammadist(X, ,

P= 0.424
Therefore, probability that the transistor will last between 12 and 24 weeks is 0.424
