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(

Now we can find the solutions:
The excel formula used to create Figure one is as follows:

Well it will be a simple as grid algebra
3(2+12)+12x5
The price would decrease because they want to get rid of the tomatoes
The correct answer here is that if the skydiver is falling 176 feet per
second, he is falling 10560 feet per minute. This can be worked out
quite easily, by considering that if there are 60 seconds in a minute,
we then need to work out the proportion of 176 feet/1 sec = x/60 sec.
You then need to multiply 60 by 176 to get 10560, which is your answer.
