Question

2) The TLV-TWA value for Chemical-A is ‘Your Student ID’ ppm. TLV-TWA for Chemical-B is ‘Your Student ID in reverse order’ ppm (For example suppose your ID is 1234, then TLV-TWA for chemical-B is 4321). Is it acceptable for a setting of exposure to 25000 ppm of Chemical-A and 35000 ppm of Chemical-B for 8 hours? Show your calculations.

Answer #1

Let a, b, and c be the last three digits of your student ID.
Find the minimum and maximum of the function f(x,y) = 3x +xy+2y on
the triangle with corners (a +b+c0. 0,a +b+c) (a +b+c,2a+2b
+2c).
a=4 b=1 c=8

1. (a) explain the physical meaning of affinity.
(b) What is the value in chemical equilibrium?
(c) as reactant species are consumed more, is the affinity
reduced or increased? Show your reasoning. (10 points)
2. Calculate the Gibbs Free Energy Change and evaluate the
possibility of the following reaction:
CH4 (g) + 2O2 (g) à CO2 (g) +
2H2O (l) (15 points)

Question ID 2-22: Consider a person whose happiness from the
consumption of goods (C) and time away from paid work (L) is
characterized by the function U = C2L.(C squared L). When working
they can earn $10 per hour and have 10 hours per day available for
work. They receive a gift of $5 per day regardless of how much they
work. Answer the following: (a) What is their reservation wage? (b)
What is their optimal choice of work time...

Let the population have N=7 units, with {(unit,value)} =
{(A,-1),(B,+1),(C,-2),(D,+3),(E,-4),(F,+5),(G,-6)}. The design is
as follows: first choose A or B at random; if A then choose from
{C,D} at random, if B then choose from {E,F,G} at random. 1) Find
the first-order inclusion probabilities (note that the sample size
n is fixed at 2).
Verify (show numerically for this example) that the
Horvitz-Thompson estimator is unbiased for the population total.
(Hint: find the probability of each sample and the value...

Your division is considering two projects with the following
cash flows (in millions):
0 1 2 3 Project A -$19 $8 $15 $17
Project B -$17 $11 $8 $6
What are the projects' NPVs assuming the WACC is 5%? Round your
answer to two decimal places. Do not round your intermediate
calculations. Enter your answer in millions. For example, an answer
of $10,550,000 should be entered as 10.55. Negative value should be
indicated by a minus sign.
