O’Sullivan Corp. purchased 75% of the outstanding shares of Rabb Ltd. on January 1, Year 3, at a cost of $214,200. Non-controlling interest was valued at $75,000 by an independent business valuator at the date of acquisition. On that date, Rabb had common shares of $70,000 and retained earnings of $50,000. Fair values were equal to carrying amounts for all the net assets except the following: Carrying Amount Fair Value Inventory $ 50,000 $ 29,000 Equipment 49,000 79,000 Software 25,000 The equipment had an estimated remaining useful life of six years on January 1, Year 3, and the software was to be amortized over ten years. Foxx uses the cost method to account for its investment. The testing for impairment at December 31, Year 6, yielded the following fair values: Software $ 12,000 Goodwill 127,258 The impairment loss on these assets occurred entirely in Year 6. Amortization expense is grouped with administrative expenses, and impairment losses are grouped with miscellaneous expenses. The parent’s share of the goodwill noted above is $92,902.

This question is Statistical mechanics. Please answer all the questions, clearly write all formulas used. Problem: Consider an assembly of N = 3 particles obeying Fermi-Dirac statistics. Each particle has the following degenerate energy levels, ϵn = nϵ where n = {0, 1, 2, 3} having degeneracies g0 = 1, g1 = g2 = 2, g3 = 3. The system has a fixed total energy U = 4ϵ. (a) Identify the macrostates of the system. (b) Hence, obtain the thermodynamic probability, Ω, of the system. (c) Which macrostate configuration is most likely to occur? Give a reason for your answer. (d) Compute the average population, N¯ j , of each energy level of the system.

Chapter 7: Bond Valuation Problem 7.04 (Yield to Maturity) eBook Check My Work (3 remaining) A firm's bonds have a maturity of 14 years with a $1,000 face value, have an 11% semiannual coupon, are callable in 7 years at $1,237.77, and currently sell at a price of $1,407.49. What is their nominal yield to maturity? Do not round intermediate calculations. Round your answer to two decimal places. % What is their nominal yield to call? Do not round intermediate calculations. Round your answer to two decimal places. % What return should investors expect to earn on these bonds? I. Investors would expect the bonds to be called and to earn the YTC because the YTM is less than the YTC. II. Investors would expect the bonds to be called and to earn the YTC because the YTC is greater than the YTM. III.

The Hamiltonian for an axially symmetric rotor (a symmetric top) is given by \begin{equation*} H = \frac{1}{2I_1}(L_x^2 + L_y^2) + \frac{1}{2I_2}L_z^2 \end{equation*} where $I_1$ and $I_2$ are the moments of inertia of the rotor. (They are just constants.) a. Use the fact that $L^2 = L_x^2 + L_y^2 + L_z^2$ to find the energies for the symmetric rotor. b. What are the degeneracies of the first three energies?
