Suppose stock B has a standard deviation of [sb]%. Stock S has a standard deviation of [ss]%. The correlation coefficient of stocks B’s and S’s returns is [rho]. What is the standard deviation of a portfolio consists of [wb] stock B and the rest stock S.

5. A satellite orbiting the earth completes one revolution per day and is traveling at a linear speed of miles per hour. How far is the satellite from the center of the earth? Give your answer in miles, rounded to the nearest whole number.

2. Find an angle coterminal with

As a result of any natural process, the total entropy of any system plus that of its environment  

Suppose you observed returns of [r0]%, [r1]%, [r2]%, and [r3]% for a stock over the past four years. What is the standard deviation of the stock’s returns based on historical data?

A 0.10m3 gas tank holds 5.0 moles of nitrogen gas (N2), at a temperature of 370K.  The atomic mass of nitrogen is 14 g/mol, the molecular radius is 3.0 × 10-10 m, and the Boltzmann constant is 1.38 × 10-23 J/K. What is the root-mean-square speed (thermal speed) of the molecules? [vrms]

A 610-g quantity of an ideal gas undergoes a reversible isothermal compression at a temperature of 330K.  The compression reduces the volume of the gas from 0.40 m3 initially, to 0.21m3 finally. The molecular mass of the gas is 33.0 g/mol, and the ideal gas constant is R = 8.314 J/(mol ∙ K). What is the entropy change for the gas for this process? [entropy]
