a. Mortgage servicers collect the payments from the borrowers and forward them to the mortgage owners. Servicing rights are often sold separately from the mortgages themselves. Based on your answers to problem 2, comment on the valuation and effective duration of servicing rights. Assume that the servicer receives .03125% per month of the outstanding balance (.375% annually), and provide a quantitative estimate of the present value of the servicing rights under the three interest rate and prepayment scenarios in part b.

Move Semantics Which of the following is true about the assignment x = std:: move (y) in C++17 and C++20, assuming x and y are both of the same type and that the appropriate header files are visible? Pick ONE OPTION it is always strictly faster than the assignment x = y it may induce a compiler error reading from y after the assignment is undefined behavior after the assignment, it is guaranteed that x!= y, assuming that operator!= is defined for the type of the variables
Exercise 2.3 Let S = {1,2,3,4,5,6,7,8} and for $A \subseteq S$ define a probability measure by $\frac{1}{12}(|A \cap \{1,2,3,4\}| + 2|A \cap \{5,6,7,8\}|)$. (a) Verify that this satisfies the axioms for probability.
You shine light of wavelength 599 nm at normal incidence onto a grating with 606 lines/mm. How many diffracted orders will you observe (include the 0th order, and e.g. the +/-1 orders together count as 2)?
Exercise 23-8 (Algo) Segment elimination LO P4 Marin Company makes several products, including canoes. The company reports a loss from its canoe segment (see below). All its variable costs are avoidable, and $312,500 of its fixed costs are avoidable.

11. Describe the variation of skin depth with temperature. 12. According to the discussion in Section 4.11, free electrons make a negative contribution to the dielectric constant, while bound electrons make a positive contribution. Explain this difference in electron behavior.
Above is a unit circle with a distance t starting at point (1,0) and ending at the terminal point with the indicated x-coordinate. We want to find the distance t, but it is NOT arccos(-0.7). Why? By making an adjustment to arccos(-0.7), find the distance t exactly. HINT: Where is the distance arccos(-0.7) on the unit circle? How is it related to our distance t?
