Suppose that Y has a gamma distribution with parameters α and β. a If a is any positive or negative value such that α + a > 0

, show that E(Ya ) = βa(α + a) (α) . b Why did your answer in part (a) require that α + a > 0? c Show that, with a = 1, the result in part (a) gives E(Y ) = αβ. d Use the result in part (a) to give an expression for E( √Y ). What do you need to assume about α? e Use the result in part (a) to give an expression for E(1/Y ), E(1/ √Y ), and E(1/Y 2). What do you need to assume about α in each case?

Please help me with thissss
Evgesh-ka [11]

Answer:

a.) The sum of the weights of the two in insects is 0.0031 grams. (0.0031 grams)

b.) The fly is 0.0013 grams heavier than the gnat. (0.0013 grams)

Step-by-step explanation:

2.2 * 10^-3 = 2.2 * 1/1000 which is 2.2/1000.

9 * 10^-4 = 9 * 1/10000 = 9/10000

To add 9/10000 to 2.2/1000 we have to find the common denominator, which will be 10000.

So we do:

2.2/1000 * 10/10 = 22/10000

9/10000 + 22/10000 = 31/10000 = 0.0031.

The sum of the weights of the two in insects is 0.0031 grams.

To find how much heavier the fly is than the gnat we do:

22/10000 - 9/10000 = 13/10000 = 0.0013

The fly is 0.0013 grams heavier than the gnat.

Smaller numbers are to the left, and larger numbers are to the right.

but since both is in the 3,000 just make sure one is on the left and find out where the bigger one goes on the right

Manuel bought 9 pounds of apples. He has eaten 1.5 pounds so far and has $15
Artyom0805 [142]

Answer:

  • $2 per pound
