Stock a has an expected return of 12%, a beta of 1.2, and a standard deviation of 20%. stock b also has a beta of 1.2, but its expected return is 10% and its standard deviation is 15%. portfolio ab has $300,000 invested in stock a and $100,000 invested in stock b. the correlation between the two stocks' returns is zero (that is, ra, b = 0). which of the following statements is correct? a. the stocks are not in equilibrium based on the capm; if a is valued correctly, then b is overvalued. b. the stocks are not in equilibrium based on the capm; if a is valued correctly, then b is undervalued. c. portfolio ab's expected return is 11.0%.d. portfolio ab's beta is less than 1.2.e. portfolio ab's standard deviation is 17.5%.

Imagine us is a startup that offers high definition 3d prenatal ultrasounds for high-end customers. the service process includes four activities that are conducted in the sequence described below. (the time required for each activity is shown in parentheses): activity 1: welcome a patient and explain the procedure. (20 minutes)activity 2: prep the patient (e.g., show them to the room, apply ultrasound gel). (17 minutes) (*your id number represents the amount of time needed to complete this task)activity 3: take images. (5 minutes)activity 4: discuss diagnostic with patient. (20 minutes)at each location there are employees (servers) s1, s2, and s3. the assignment of tasks to servers is the following: s1 does activities 1 and 2.s2 does activity 3.s3 does activity 4.a. what is the capacity of this process (in customers per hour)? b. suppose 3 patients arrive every hour on average. ignoring any “start of day” or “end of day” effects, what are the utilizations of all three servers (%)? c. suppose each activity can be done by any server and any server can do any set of activities. however, each activity is done by only one server. for example, a possible assignment includes: s1 does activity 1, s2 does activity 2, and s3 does activities 3 and 4. of course, the original assignment of servers to activities is also feasible. what is the maximum capacity of the process (in customers per hour)? d. now consider the capacity measures in (c) and (a), what is the percentage change? why can you improve capacity without using additional resources? (there is no free lunch, right? )note: for all hw assignments, show your process of getting the results. only providing the final answers is not acceptable and will get 0%. if necessary, use a separate sheet of paper to show your work.

Which of the following statements is true of the balanced-scorecard? a. it is a more or less a one-dimensional metric of measuring competitive advantages of a firm. b. it is one of the traditional approaches of measuring firm performance. c. its primary focus is to base a firm's strategic goals entirely on external performance dimensions. d. it attempts to provide a holistic perspective on firm performance.
