Question 1 Suppose that I is a continuous random whose probability density function
is given by
ーこくこく
fx (2) =
Kexp().
Kexp(-). <<<
where K is some constant and > 0.

a) Show that K =
15
b) Show that the cumulant generating function of X. Cxt), is given by
CX(t) = tu - in 1 - 292)
c) Hence, or otherwise, show that E(X) = p and Var(X) = 292

d) Determine the distribution function. FX(t), for X.

3. manufacturing institutions, because capitalists  are about making money. 

Which of the following is an example of an opposing signal? no examplthates given.   i would say, that traffic lights in a city at major intersections direct the flow of traffic in opposite directions so would be an example.also, stop signs on either side of the same street would be an example. at a train crossing, the light for allowing car traffic in opposite directions or not would be another example.
