Answer:
1.External rate of return(ERR) method directly takes into account the interest rate external to a project at which net cash flows generated or required by the project over its life can be borrowed and reinvested. Net cash flows are discounted, net cash flows are to be compounded and then Err is calculated. So we would get only one solution. Hence, the correct option is True.
2. Internal rate of return (IRR) is a measure of an investment's rate of return that excludes the external factors. On the other hand, Minimum acceptable rate of return(MARR) is the minimum rate of return on a project a company is willing to accept before starting a project. There is a strong link between IRR, ERR and MARR. When IRR > MARR, the IRR > ERR > MARR. So the correct option is A. ERR < IRR.
The external rate of return (ERR) method will only have one solution (one rate or return...
(a) For what value of x does f(x) = g(x)? (b) For which values of x is f(x) >g(x)? For every x in the interval f(x)>g(x). (Type your answer in interval notation.) In parts (a) and (b), use the given figure. (a) Solve the equation: f(x) = g(x). (b) Solve the inequality f(x) > g(x). у y = g(x) y = f(xN (-9,7)
3. Let X1,... ,Xn be a random sample from a population with pdf 0, otherwise, where θ > 0. (a) Find the method of moments estimator of θ. (b) Find the MLE θ of θ. (c) Find the pdf of θ in (b).
(b) Trace the following code. // Precondition: n > 0 // <method description here> public static int dothing (int n) { int ans = ; for (int x 1; x <= n; x++) ( for (int y = x; y <= n; y++) ( ans+ } return ans; } (ii) If you were asked to write a one-line description above this method, what would it be? (iii) Could you rewrite the method so that it runs more efficiently?

5. Given y,-t is a solution of t2y" + 2t1-2y = 0, for t > 0, find a second solution y2.
The gas phase decomposition of hydrogen peroxide at 400 °C H2O2(g)—>H2O(g) + 42 O2(g) is second order in H2O2. In one experiment, when the initial concentration of 1,02 was 0.153 M, the concentration of H2O2 dropped to 2.51x10-2 M after 36.1 seconds had passed. Based on these data, the rate constant for the reaction is M's-1 The gas phase decomposition of nitrogen dioxide at 383 °C NO2(g)—>NO(g) + 12 02(g) is second order in NO, with a rate constant of...
