Oil production. Assume that the rate in Problem 83 is found to be R ( t ) = 120 t t 2 + 1 + 3 0 ≤ t ≤ 20 (A) When is the rate of production greatest? (B) How many barrels of oil Q ( t ) will the field produce in the first t years if Q (0) = 0? How many barrels will be produced in the first 5 years? (C) How long (to the nearest tenth of a year) will it take to produce a total of a quarter of a million barrels of oil?

Solution Summary: The author explains how the rate of greatest production is calculated by dividing R(t) with respect to t.
Given sets X and Y with X ∈ Y, is it always true that P (X) ∈ P (Y) (power sets)? If not, what is a counterexample?
A random variable X takes values 0 and 1 with probabilities q and p, respectively, with q+p=1. find the moment generating function of X and show that all the moments about the origin equal p. (Note- Please include as much detailed solution/steps in the solution to understand, Thank you!)
1 (Expected Shortfall)
Suppose the price of an asset Pt follows a normal random walk, i.e., Pt =
Po+r₁ + ... + rt with r₁, r2,... being IID N(μ, o²).
Po+r1+.
⚫ Suppose the VaR of rt is VaRq(rt) at level q, find the VaR of the price
in T days, i.e., VaRq(Pt – Pt–T).
-
• If ESq(rt) = A, find ES₁(Pt – Pt–T).
