Suppose that many stocks are traded in the market and that it is possible to borrow at the risk-free rate, rƒrƒ . The characteristics of two of the stocks are as follows: StockExpected ReturnStandard DeviationA8%40%B12%60%Correlation = −1 Required: Calculate the expected rate of return on this risk-free portfolio? (Hint: Can a particular stock portfolio be formed to create a “synthetic” risk-free asset?) Note: Round your answer to 2 decimal places. Could the equilibrium rƒrƒ be greater than rate of return? multiple choice Yes No

Take me to the text For the upcoming year, Kinston Quart Limited expects to generate $4,120,000 of revenue. Based on historical trends, the company makes the most sales in the first two quarters. As a result, it assumes that the first and second quarter will each contribute 28% of the annual revenue. The remaining budgeted amount will be allocated equ between the last two quarters. For each quarter, calculate the budgeted sales in dollars. Do not enter dollar signs or commas in the input boxes. Round all answers to the nearest whole number.

A study published in the journal Pediatrics shows that infants who are breast fed have a much lower risk of developing diarrhea when compared to infants who are fed formula. A different study reports that while many infants contain bacteria in their digestive system that would cause diarrhea in adults, breast fed infants do not become ill. A bacterium specific to the human digestive system produces a toxin which irritates the lining of the digestive system resulting in diarrhea. Breast milk contains a protein which binds to the toxin produced by the bacteria resulting in it being ineffective.The protein found in breast milk is produced when

1) a)in this problem you are guided through three steps to derive the a representation of the Dirac delta function in momentum space. *Consider the inverse transform from momentum to position space $\psi(x) = \frac{1}{\sqrt{2\pi\hbar}} \int dp' e^{ip'x/\hbar} \phi(p')$ Eq.1 *Now write the forward transform to obtain $\phi_p(p)$ in terms of $\psi(x)$ and substitute Eq 1. *Organize the integrals and terms to identify the Dirac delta function in momentum space: $\delta(p'-p) = \frac{1}{2\pi\hbar} \int dx e^{-ip'x/\hbar} e^{ipx/\hbar}$ >Show all you work to get full credit. b) In this problem you are guided through three steps to obtain the function associated with $(x|p)$. Preliminary steps. Consider the eigen value problem for the momentum operator: $\hat{p}|p\rangle = p|p\rangle$ If we act with $\langle x|$ we get $\langle x|\hat{p}|p\rangle = \langle x|p|p\rangle$ $-i\hbar\frac{\partial}{\partial x} \langle x|p\rangle = p\langle x|p\rangle$ *Solve the differential equation and show that the function $(x|p) = f_p(x)$ (according to Griffiths) is given by: $(x|p) = f_p(x) = Ae^{ipx/\hbar}$ *Without substituting explicitly for the functions, show that $\int dx f_p^*(x) f_{p'}(x) = \langle p|p'\rangle = \delta(p'-p)$ > You may find useful the identity operator in positions space 1 *Now substitute for the functions and from the result of part a) show that $|A|^2 = \frac{1}{\sqrt{2\pi\hbar}}$
