0.560 g He, 20.482 g F2, and 13.960 g Ar are placed
in a 18.4-L container at 25 oC. What are the molar
concentrations and partial pressures of the gases?
(All values to the nearest 0.0001)

Let X ∼ Pois(4), Y ∼ Pois(12), U ∼ Pois(3) be independent random variables.
a) What is the exact sampling distribution of W = X + Y + U?
b) Use R to simulate the sampling distribution of W and plot your results. Check that the simulated mean and standard error are close to the theoretical mean and standard error.
c) Use the simulated sampling distribution to estimate P(W ≤ 14) and then check your estimate with an exact calculation.

A sample mixture of ethyl benzoate (bp 212 C) and dodecane (bp 216.2 C) is injected on two GC columns. Column A has DC710 silicone oil as the stationary phase, and column B uses polyethylene glycol as the stationary phase. Which substance would be certain to elute first from column A and would the same material be expected to elute first from column B? Which column, A or B, would be expected to give the better separation of these two substances?

Consider the markets for fossil fuels (oil, coal, natural gas) and alternative energy sources (solar, wind, geothermal power etc). Due to the current climate change, let's say we desire to have people use less of the fossil fuels (which produce greenhouse gasses that cause global warming) and more of the alternative energy sources. Using the concepts of Supply and Demand, discuss how the government can use policies to shift these curves, and what the results will be on the quantities and prices of the fossil fuels and the alternative fuels.

Which notion from below best explains people's decision-making process from an economic perspective?
People's behavior reflects rational self-interest
Costs are more important than benefits
Land is a scarce resource while labor is not
Scarcity is more important than choice
The government Yelpia decides to build more four-year universities. Consequently, the resources used for the program become unavailable for improvements in the high school system. This problem demonstrates the concept of:
Unintended consequences.
Industry-specific unemployment.
Opportunity cost.
Production expenses.
Economics studies remarkably complex problems of real life by constructing models. Those models are made by using:
Tradeoffs
Simplifications
Predictions
Value judgments
Angela notes that "a study shows that there is a high level of student debt in the US." Greg agrees and adds that "government should make the college free."
Both Angela's and Greg's statements are normative
Both Angela's and Greg's statements are positive
Angela's statement is positive while Greg's statement is normative

Ms/P = Mo/P + ΔRE/P
Foreign Exchange Market
NX = NXo – mY + vθ + γYf
CF = CFo + f (i – if)
ΔRE/P = NX + CF
Endogenous Variables: C, YD T, I, X, IM, L, Ms, CF, NX, Y, i and .RES/P
Exogenous Variables: Co, To, Io, Go, TRo, Xo, Yf, IMo, Mo, CFo, NXo, i, if and P
Parameters: c, t, b, λ, γ, ψ, m, f, k, h and v
Policy variables: Fiscal policy: (G, t and TR) Monetary policy: (Mo, P) and Exchange Rate: (θ)
1. Explain the general role of parameters λ, γ, ψ, m, f, k, h, v in the algebraic model
2. For the macroeconomic model given, identify the ER (exchange rate) system and the extent of capital mobility (perfect or imperfect) in this economy.
3. Assume that the economy is initially in internal-external equilibrium, show the effects of a devaluation of the real exchange rate (increase in θ), on interest rate i* and output Y*, in an IS-LM-BP space.
4. Provide a brief written description of the adjustment process that occurs in no. 3 above.
5. Use qualitative analysis (state direction of change, do not calculate any values) and clearly describe in words, the ultimate impact of the above policy on the equilibrium level of the following endogenous variables:
6. Explain the costs of devaluation and the ‘J Curve effect’

Suppose an inflationary economy can be described by the following equations representing the goods and money markets:
C = 20 + 0.7Yd
M = 0.4Yd
I = 70 – 0.1r
T = 0.1Y
G = 100 X = 20
Ld = 389 + 0.7Y – 0.6r
Ls = 145
where G represents government expenditure, M is imports, X is exports, Y is national income, Yd is disposable income, T is government taxes (net of transfer payments), I is investment, r is the rate of interest, C is consumption, Ld is money demand, and Ls is money supply.
i) Use the inverse matrix method to solve for the equilibrium level of national income and the equilibrium rate of interest in this economy. (Note: ½ of the marks in this part are given for the correct set up of the equations. Explain what you are doing, including how equilibrium is established in each market.)
ii) Now use Cramer’s rule to find your answer.

| Apr. 15. | Received cash from Pinecrest Co. for the balance owed on April 1. | |
| Apr. 16. | Issued Invoice No. 796 to Pinecrest Co., $6,370. Post revenue and collections to the accounts receivable subsidiary ledger. |
|
| Apr. 19. | Received cash from Ohr Co. for the balance due on invoice of April 2. | |
| Apr. 20. | Received cash from Pinecrest Co. for balance due on invoice of April 6. | |
| Apr. 22. | Issued Invoice No. 797 to Mendez Co., $8,390. | |
| Apr. 25. | Received $2,320 note receivable in partial settlement of the balance due on the Shilo Co. account. | |
| Apr. 30. | Received cash from fees earned, $14,320. Post revenue and collections to the accounts receivable subsidiary ledger. |
Required:
1. Insert the following balances in the general ledger as of April 1:
| 11 | Cash | $13,030 |
| 12 | Accounts Receivable | 15,870 |
| 14 | Notes Receivable | 6,910 |
| 41 | Fees Earned | - |
After completing the recording of the transactions in the journals in part 3, total each of the columns of the special journals, and post the individual entries and totals to the general ledger. Insert account balances after the last posting. When posting to the general ledger, post in chronological order. However, if there is more than one entry on the same date, be sure to post transactions from the revenue journal before posting transactions from the cash receipts journal.
If an amount box does not require an entry, leave it blank. In CNOW, Journal pages begin with “J”, Cash Receipts begin with “CR” and Cash Receipts begins with “R”. For example journal/ Cash Receipts/ Cash Receipts, page 1/36/40 respectively. POST. REF. is simply J1, CR36, and R40.

| Shilo Co. | - |
After completing the recording of the transactions in the journals in part 3, post to the accounts receivable subsidiary ledger in chronological order, and insert the balances at the points indicated in the narrative of transactions. Determine the balance in the customer's account before recording a cash receipt. If an amount box does not require an entry, leave it blank. In CNOW, Journal pages begin with “J”, Cash Receipts begin with “CR” and Cash Receipts begins with “R”. For example journal/ Cash Receipts/ Cash Receipts, page 1/36/40 respectively. POST.

3. Prepare a single-column revenue journal (p. 40) and a cash receipts journal (p. 36). Use the following column headings for the cash receipts journal: Fees Earned Cr., Accounts Receivable Cr., and Cash Dr. The Fees Earned column is used to record cash fees.
4. Using the two special journals and the two-column general journal (p. 1), journalize the transactions for April. Post to the accounts receivable subsidiary ledger, and insert the balances at the points indicated in the narrative of transactions. Determine the balance in the customer’s account before recording a cash receipt.
5. Total each of the columns of the special journals and post the individual entries and totals to the general ledger. Insert account balances after the last posting.
