An investor wants to determine the safest way to structure a portfolio from several investments. investment a produces an average annual return of 14% with a variance of 0.025. investment b produces an average rate of return of 9% with a variance of 0.015. investment c produces an average rate of return of 8% with a variance of 0.010. investments a and b have a covariance of 0.00028, and investments a and c have a covariance of -0.006. investments b and c have a covariance of 0.00125.
a. suppose the investor wants to achieve at least a 12% return. what is the least risky way of achieving this goal? round the answers for portfolio investments to one decimal place and portfolio variance to four decimal places. investment a % b % c % variance
b. suppose the investor regards risk minimization as being five times more important than maximizing return. what portfolio would be most appropriate for the investor? round the answers for portfolio investments to one decimal place and portfolio variance to four decimal places. investment a % b % c % variance

Total marketing effort is a term used to describe the critical decision factors that affect demand: price, advertising, distribution, and product quality. define the variable x to represent total marketing effort. a typical model that is used to predict demand as a function of total marketing effort is based on the power function: d = axb suppose that a is a positive number. different model forms result from varying the constant b. sketch the graphs of this model for b = 0, b = 1, 0< b< 1, b< 0, and b> 1. (we encourage you to use excel to do this.) what does each model tell you about the relationship between demand and marketing effort? what assumptions are implied? are they reasonable? how would you go about selecting the appropriate model?
