Here are the estimated ROE distributions for Firms A, B, and C: Probability 0.1 0.2 0.4 0.2 0.1 Firm A: ROEA 0.0% 5.0% 10.0% 15.0% 20.0% Firm B: ROEB (2.0) 5.0 12.0 19.0 26.0 Firm C: ROEC (5.0) 5.0 15.0 25.0 35.0 a. Calculate the expected value and standard deviation for Firm C’s ROE. ROEA 10.0%, A 5.5%; ROEB 12.0%, B 7.7%. b. Discuss the relative riskiness of the three firms’ returns. (Assume that these distributions are expected to remain constant over time.) c. Now suppose all three firms have the same standard deviation of basic earning power (EBIT/ Total assets), ABC 5.5%. What can we tell about the financial risk of each firm?

The following table contains some standard enthalpies of formation, $\Delta H^\circ_f$, at 298 K. \begin{tabular}{lll} Substance & Formula & $\Delta H^\circ_f$ (kJ/mol) \\ Carbon dioxide & CO$_2$(g) & -393.5 \\ Carbon monoxide & CO(g) & -110.5 \\ Methane & CH$_4$(g) & -74.80 \\ Propane & C$_3$H$_8$(g) & -103.85 \\ Water & H$_2$O(l) & -285.8 \\ Water vapor & H$_2$O(g) & -241.8 \\ \end{tabular} Many portable gas heaters and grills use propane, C$_3$H$_8$(g). Using enthalpies of formation, calculate the quantity of heat produced when 20.0 g of propane is completely combusted in air under standard conditions. Assume that liquid water is forming. Express the heat in kilojoules to three significant digits. Q = -960 kJ

The temperature of an air stream flowing with a velocity of 3 m/s is measured by a copper constantan thermocouple which may be approximately as sphere of 2.5 mm in diameter. Initially the junction and air temperature of ($T_i = 25^\circ C$). The air temperature suddenly changes to and is maintained at ($T_\infty = 215^\circ C$). The thermal junction properties are: $\rho = 8750 \text{ kg/m}^3$; $C_p = 380 \text{ j/kg}^\circ C$; k (thermocouple) = 28 w/m$^\circ$C; h = 145 w/m$^2$$^\circ$C Volume = 4/3 ($\pi r^3$) and A = $4\pi r^2$ Determine (a) Biot number (b) the time required for the thermocouple to indicate a temperature of 165$^\circ$C
