How much did you spend running your 40 Watt light bulb for one hour?(a) What is the volume (in km3) of Avogadro’s number of sand grains if each grain is a cube and has sides that are 1.0 mm long? (b) How many kilometers of beaches in length would this cover if the beach averages 100 m in width and 10.0 m in depth? Neglect air spaces between grains.58. A retired partner from a large brokerage firm hasone million dollars available to invest in particularstocks or bonds. Each investment’s annual rate ofreturn depends on the state of the economy in thecoming year. The file P09_58.xlsx contains thedistribution of returns for these stocks and bonds asa function of the economy’s state in the coming year.As this file indicates, the returns from stocks andbonds in a fair economy are listed as X and Y. Thisinvestor wants to allocate her one million dollars tomaximize her expected value of the portfolio oneyear from now.a. If X 5 Y 5 15%, find the optimal investment strategy for this investor. (Hint: You could try a decisiontree approach, but it would involve a massive tree.It is much easier to find an algebraic expression forthe expected final value of the investment whena percentage p is put in stocks and the remainingpercentage is put in bonds.)b.
