Derive the following. Do not use quantifier exchange rules (in case you happen to know
what they are.)

1). ∃x(Fx v Gx) ├ ∃xFx v ∃xGx

2) ∃xFx → ∀yGy, ∀xFx ├ ∀zGz

3) ∀x(Fx → ∀y(Gy → Hxy)), ∃x(Fx & ∃y~Hxy) ├ ∃x~Gx

Derive the following using all known inferences rules and equivalences including QE. Remember that equivalences afford you greater power than derivation rules, because you are permtted to substitute equivalent sub formlas within a wff. For example, all the moves on the left below are legitimate inferences even though the first conditional is the main operator. However, it is important to remember that you must always be operating on a true self-contained wff. The moves on the right are not legitimate...

How do you know that the determinant of a variance-covariance matrix must be greater than or equal to zero? The answer is one short sentence. ( Let x and y be scalar random variables. Recall Corr(x, y) = √ Cov(x,y) . Using V ar(x)V ar(y) what you have shown about the determinant, show −1 ≤ Corr(x,y) ≤ 1.

You are analyzing the market for Good X. You know the following: PEDx = -1.3 IEDx = 2.4 CPE(x,y) = 2 PESx = 1.4 a. If the price of Good Y increases, what do you expect to happen in the market for Good X? Describe any changes that may happen in a supply/demand graph and be sure to include how equilibrium price/quantity changes. b. Does knowing the price elasticity of supply help you determine how much the supply curve will...

For each of the following situations, use the IS-LM-FX model to illustrate the effects of the shock. Please explain how you obtained your answer (do not just state the effect). For each case, state the effect of the shock on the following variables (increase, decrease, no change, or ambiguous): Y, i, E, C, I and TB. Assume the government allows the exchange rate to float and makes no policy response. 1. The money supply increases. 2. Government spending increases. 3....
