Question A monopolist faces market demand of P = 200 - Q. Its MR = 200 - 2Q, MC = 2Q, and ATC = Q. Determine the monopolist's quantity produced, price, profit, and deadweight loss. The monopolist's quantity is The monopolist's price is $ : The monopolist's profit is $0 The monopolist's deadweight loss is $ 1. (Round to the nearest cent as needed.)

Firm 1 and firm 2 are Bertrand duopoloists. Firm 1 has a marginal cost of $6.00 per unit, and firm 2 has a marginal cost of $8.01 per unit. The demand for their product is p=23.00−Q, where Q is the total quantity demanded. How much does each firm sell in equilibrium? Assume that prices can only be set to the nearest cent, firms split the market if they set the same price, and there are no fixed costs. Firm 1 production:______ Firm 2 production:______ What are the profits for each firm in equilibrium? Firm 1 profit:   $______ Firm 2 profit:   $______

Suppose the interest rates on a European bond and an Australian bond are 2% and 4% per year, respectively. The exchange rate today is 0.6 Euro per Australian dollar. If the interest parity condition holds, what must be the expected exchange rate between the Euro and the dollar? (Note: round your result to 2 decimal places.) 0.61 $/€ 0.59 $/ € 1.70 $/€ 1.63 $/ € 0.82 $/ €

If the representative basket of European goods and services costs 60 euros, the representative U.S. basket costs $50, and the dollar/euro exchange rate is $1.50 per euro, then the price of the European basket in terms of U.S. basket is 4500 U.S. basket/European basket. 1.25 U.S. basket/European basket 0.8 U.S. basket/European basket. 1.8 US. Basket/European basket 0.56 U.S. basket/European basket

5 In a study relating college grade point average to time spent in various activities, you distribute a sur- vey to several students. The students are asked how many hours they spend each week in four activi- ties: studying, sleeping, working, and leisure. Any activity is put into one of the four categories, so that for each student, the sum of hours in the four activities must be 168. (1) In the model GPA = Be + B study + B sleep + B;work + B.leisure + . does it make sense to hold sleep, work, and leisure fixed, while changing study? (ii) Explain why this model violates Assumption MLR.3. 106 PART 1 Regression Analysis with Cross-Sectional Data (iii) How could you reformulate the model so that its parameters have a useful interpretation and it satisfies Assumption MLR.3? Consider the multiple regression model containing three independent variables, under Assumptions MLR.1 through MLR.4: y = Bo + B x1 + Boxe + Byty + u. You are interested in estimating the sum of the parameters on X, and Xz; call this 0,- B. + B.. 0 Show that 8, = B. + B, is an unbiased estimator of 8, (ii) Find Varê) in terms of Var(B).Var(B2), and Corr(B.B.).

Question 6 [10 points] Find all complex numbers z such that z2=-2i, and give your answer in the form a+bi. Use the square root symbol 'V' where needed to give an exact value for your answer. =- z= ???

Please include the photo of output Write a C++ program to simulate the following system: An alarm system has three different control panels in three different locations. To enable the system, switches in at least two of the panels must be in the on position. If fewer than two are in the on position, the system is disabled. Notes: 1. You can't use if statement or any type of comparisons to implement simulations 2. As an output you need to provide the input/output tables of the given circuit
