What is the modified IRR of the investment?

c$.75\mathrm{.}5\%$ Suppose the expected return and standard deviation of stock A is $10\%$ and $20\%$ respectively. The expected return and standard deviation of stock B is $15\%$ and $28\%$ respectively. The correlation between A and B is $0\mathrm{.}4.$

A portfolio P consulting of only these two stocks has an expected return of $14\%.$ What is the standard deviation of P$?$

a$.21\mathrm{.}9\%3.$ Suppose the risk free in the market is $3\%,$ the expected return of the market portfolio is $20\%,$ and the standard deviation of the market portfolio return is $2\%.$ The covariance of the return stock A and the market portfolio is $0\mathrm{.}08.$ Based on CAPM, what is the expected return of stock A$?$
