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?

Bogdan [553]
Length from R(-2, 4) to S(3, 4) is sqrt((3 - (-2))^2 + (4 - 4)^2) = sqrt(5)^2 = 5 units

Length from S(3, 4) to T(3, -1) is sqrt((3 - 3)^2 + (-1 - 4)^2) = sqrt(-5)^2 = 5 units

Therefore, total length = 5 + 5 = 10 units.

The diameter of a dime is 17.91 mm. The diameter of a strand of human hair is
irina [24]

The diameter of a dime tells us the circumference of a dime is approximately 299 times larger than human hair.

<h3>Diameter</h3>

The diameter of an object is used to calculated the circumference or area of the object. This also helps us to know the width of a circular object.

In this problem, the diameter tells us about the length of the each quantity.

The diameter of a dime tells us how wide the coin is and the diameter if a hair tells us the width of the hair.

Comparing both values

Dime = 17.91mm

Hair = 6.0*10^-2

Divide both quantity together.

17.91 / 6.0*10^-2 = 298.5≅299
