Question 4 2.5 pts 4. When you experiment to roll two dice, assume that the random variable is the sum of outcome of the roll of the dice. The sample space consists of the collection of all possible values of the random variables (x = {2,3,4,5,6,...,12}) a. What is the probability that you have 3 as an outcome? 0.056 b. F(2) represents the probability that the sum is no greater than 2. What is the value of F(2)? 0.028 c. What is the probability that the sum is at least 3? 0.972

JoJo Jeans makes two kinds of jeans, designer and straight-leg. The demand for designer jeans (x1) and straight-leg jeans (x2) are defined by the demand relations: x1 = 1500 - 24.6p1 and x2 = 2700 - 63.8p2, where p1 and p2 represent the price of each jean type. The cost of producing designer jeans is $12 per pair, and the cost of producing straight-leg is $9 per pair. The production of jeans is subject to the following resource constraints for cloth, cutting time, and sewing time in the form: Cloth 2x1 + 2.7x2 ? 6000 yards Cutting 3.6x1 + 2.9x2 ? 8500 minutes Sewing 7.2x1 + 8.5x2 ? 15,000 minutes 10 points - Develop in Excel, and use the Solver tool, the solution to the nonlinear programming problem where the firm would like to maximize the profit across jean types subject to its constraints. Submit your Excel file where you retain the sheet where you develop the model and include the Answer report as a separate sheet. 10 points for the next 4 questions (2.5 each). What is the maximum profit attainable given the constraints? What are the values for x1 and x2 at the maximum profit? What are the values for p1 and p2 at the maximum profit? Are any of the resource constraints binding?

[b] Given matrix $B = \begin{pmatrix} 3 & 1 & -2 \\ 3 & 0 & 2 \\ 2 & 0 & -1 \end{pmatrix}$. [i] Find the co-factor matrix of matrix $B$. [ii] Choose a suitable row or column to expand in order to find the determinant of matrix $B$ and explain why. Calculate the determinant of matrix $B$, i.e. calculate $|B|$ based on this choice. Note:- A mark will be deducted if your choice is not the proper choice. [iii] Use your results from parts [i] and [ii] to find the inverse of matrix $B$, i.e. find $B^{-1}$.

Score: 0 of 1 pt End of Chapter 5.3 Acc Suppose that the perfectly competitive market illustrated in the graph is initially in long-run equilibrium (at $P_1$) and then there is a permanent decrease in the demand for the product (to $D_2$). The market will return to a long-run equilibrium when A. the market supply curve has shifted far enough to the left such that the new market equilibrium price equals $P_1$ B. the market demand curve has shifted farther to the left such that the new market equilibrium price is lower than $P_1$ C. the market supply curve has shifted far enough to the right such that the new market equilibrium price equals $P_1$ D. the market demand curve has shifted far enough back to the right such that the new market equilibrium quantity equals the original market equilibrium quantity. The new long-run equilibrium price and quantity will be where A. the new supply curve intersects the original demand curve B. the original supply curve intersects the new demand curve.
