A friend of yours contacted her bank to borrow $1m. for 9 months. Because of her credit risk, the bank quoted her an interest rate of 8% p.a. continuous compounding (Note: This is her borrowing rate, not her lending rate. Nor is it the risk-free rate or anybody else's rate). You are her financial advisor. You observe the following option and stock prices: Security Price 9-month European call whose exercise price = $40 $4 9-month European put whose exercise price = $40 $2.81 the underlying (non-dividend-paying) stock $39 What advice will you give to her? Should she go ahead and borrow from the bank? Or should she create synthetic borrowing? Please provide the full details of your recommendation.

Which of the following would produce a simple random sample of students in our class? (Mark all that apply.) Take a bag containing a marble for every person in the class, only 10 of which are red. Go around and have everyone draw one without putting it back. The 10 people that draw a red marble are in the sample. Everyone rolls a standard 6-sided die as they enter the class. Everyone that rolls a 2 is included in the sample. Take a spinner that has red & green sections. Have everyone spin the spinner once. Those that get green are in the sample. None of these would produce a simple random sample. Put everyone's name in a bowl, mix them well, and draw 12 to be in the sample. On a given day, pick the first ten people that arrive at class to be in the sample.

MICROWAVE GENERATION: A frequency generator basically consists of a oscillator. To build an oscillator, two elements are needed: a structure resonant and a device that compensates circuit losses. A typical resonant element is an RLC circuit. To operate at high frequencies, such as microwaves, for example, it is necessary to increase the resonance frequency, reducing L and C: A) The use of these components brings a great advantage due to the wide range of values existing on the market B) The use of these components brings a great advantage since they have electrical characteristics that are independent of operating frequency. C) The problem is that at high frequencies the capacitance between the inductor turns becomes significant so that we can no longer consider the inductor and the capacitor as independent elements. Which statement(s) are correct? Justify your choice(s)
