Implications of inflation and deflation Suppose that you are running a business, and you need some extra space for one year. Your bank offers you a loan of $100,000 at 0% interest. You consider borrowing this amount to buy the building, use it for one year, and then sell the building to pay back the loan. Unfortunately, the economy in which you are operating is experiencing deflation at the rate of 10% per year. After one year, you should be able to sell the building for Suppose that owning the building for a year would earn you $5,000. To decide whether you will be better off by owning it for one year and then selling it, you seek advice from three different people: (1) Your brother says that you should not buy the building because in one year it will cost you $100,000. (2) Your accountant says that you should definitely buy the building because yau can borrow $100,000 at zero interest while the building will generate $5,000 in extra income. Then when you sell it, you will be $5,000 richer. (3) Your bookkeeper says that if you sell the building in a year, you will have to come up with more money to pay off the loan than you will make in extra income. Keeping in mind that the economy experiences deflation at the rate of 10%, your is right because: When the nominal interest rate is zero, the cost of a building is its full purchase price When the nominal interest rate is zero, you do not incur any cost when you take out a loan The extra income you will earn will be less than the cost of owning the building for the year Now, suppose you inherit $100,000 in cash from your uncle who had kept it hidden in his mattress. Assuming the nominal interest rate is -1%, which of the following options will maximize the amount of cash that you have in one year? Holding on to your $100,000 in cash Buying the building, because you can earn an additional $5,000 in income if you own the building for one year and then sell it Depositing the cash in a bank, because the 10% deflation makes the value of your dollars fall even more rapidly than 1% per year 2.Implications of inflation and deflation Suppose that you are running a business, and you need some extra space for one year.

Consider the national market for electric school buses with the demand given by Qd=600-2P and supply given by Qs=3P-150. (Note: the price is in thousands of US$\$$ and quantity is in thousands of buses). 5. Price Elasticity of Demand Ed or PED a. Compute the price elasticity of demand (Ed) for a price change of $60 (\DeltaP=$60). b. Explain the meaning of the price elasticity of demand (Ed=whatever number you obtained when you computed it) for the electric school buses. c. Is the demand for these buses price elastic or price inelastic? d. Compute the change in Consumer Surplus (\DeltaCS) using the price elasticity of demand computed in 5 (use a variation this one is for a price decrease, you are dealing with a price increase). e. Compute the DWL again using the elasticity instead of demand equations f. The smaller the DWL is compared to the tax revenue the ______ the leakage is \begin{itemize} \item Smaller \item Larger \end{itemize} g. Which type of demand creates more deadweight loss? Elastic or inelastic? Why? Use graphs or words to explain.

10.10 Leg length inequality. A study evaluated the inter-examiner reliability of a leg length determination in which the longer leg was ascertained by experi- enced and inexperienced chiropractors (Holt et al., 2009). The inexperienced chiropractors had undergone extensive training before the study. Examinations Table 10.16 Data for Exercise 10.10. Rater B Rater A + - Total + 12 2 14 - 4 28 32 Total 16 30 46 References 243 were carried out in the prone position. Data in the table below represent agree- ments between the raters. The + sign indicates that the left leg was deemed to be shorter; the \textendash{} sign indicates that the right leg was deemed shorter. Evaluate the reproducibility of these results using the data in Table 10.16.

2. Let G be a group, and let H, K be subgroups of G with $K \trianglelefteq G$. The second isomorphism theorem says that $H \cap K \trianglelefteq H$ and that: $\frac{H}{(H \cap K)} \cong \frac{HK}{K}$. (a) Prove the second isomorphism theorem by applying the first isomor- phism theorem to the map $\phi: H \to \frac{HK}{K}$ $\qquad h \mapsto hK$. (b) Deduce that if G is finite, then $|HK| = \frac{|H||K|}{|H \cap K|}.$ 3. The quaternion group is the subgroup Q of GL$_2$(Z$_3$) generated by the matrices: $i = \begin{pmatrix} 1 & 1\\ 1 & 2 \end{pmatrix}$ and $j = \begin{pmatrix} 2 & 1\\ 1 & 1 \end{pmatrix}$ You can use without proof that that these satisfy the relations: $i^2 = j^2 = -I$ and $ij = -ji$. (a) Show that Q is a group of order 8. (Hint: Show that $Q = \langle i \rangle \langle j \rangle$ and use Problem 2). (b) Draw the subgroup diagram of Q. Which subgroups are normal?

A girl who has not yet begun to use conventional words typically says "bark" when she sees one of her family's many pets. The utterance in no way resembles the name of any of the animals, and her mother reports that she first produced the utterance when their poodle entered the room but now utters it whenever one of the pets approaches. The utterance would most accurately be described as: Babbling Jargon A proto word A syllogism

12. In this problem, we will will evaluate the integral $\int \sin (px) \cos (qx) dx$, where $p, q$ are real numbers, in two different ways. (a) Use the trigonometric identity $\sin A \cos B = \frac{1}{2} [\sin (A - B) + \sin (A + B)]$ to evaluate the required integral. (b) Use integration by parts first with $u = \sin (px)$ and $dv = \cos (qx) dx$ and again with $u = \cos (px)$ and $dv = \sin (qx) dx$ to evaluate the required integral. (c) Verify the results obtained in parts (a) and (b) are the same.
