Create a file named “toneA.m” with the following MATLAB code: clear all Fs=5000; Ts=1/Fs; t=[0:Ts:0.4]; F_A=440; %Frequency of note A is 440 Hz A=sin(2*pi*F_A*t); sound(A,Fs); Type toneA at the command line and then answer the following: (a) What is the time duration of A? (b) How many elements are there in A? (c) Modify toneA.m by changing “Fs=5000” to “Fs=10000”. Can you hear any difference? (d) Create a file named “tone.m” with the following MATLAB code: function x = tone(frequency,...
5. If the value of an asset increases as function: V(t) = Ke2*sqrt(t) (read as 2 times the square root of t), how long should this asset be held given a discount rate = r?
1. Suppose that Xi,..,Xn are independent Exponential random variables with density f(x; λ) λ exp(-1x) for x > 0 where λ > 0 is an unknown parameter (a) Show that the τ quantile of the Exponential distribution is F-1 (r)--X1 In(1-7) and give an approximation to Var(X(k)) for k/n-T. What happens to this variance as τ moves from 0 to 1? (b) The form of the quantile function in part (a) can be used to give a quantile-quantile (QQ) plot...

(1) A wave is traveling in the positive-y direction with wavelength λ f Hz. At t is 6m 12 m and frequency 0, there is no displacement of the medium at the origin, but its amplitude a) Write the equation for the displacement of this wave as a function of position and (b) Draw a quantitatively accurate history graph (at y 3m) and snapshot graph (at t 2s) (c) What is the speed of the wave?
