I need the solution of this question asap 3, Cov(X1, X2) = 2, Cov(X2, X3) = -2, 5. Let Var(x1) = Var(X3) = 2, Var(X2) Cov(X1, X3) = -1. i) Suppose Y1 = X1 - X2. Find Var(Y1). ii) Suppose Y2 = X1 – 2X2 – X3. Find Var(Y2) and Cov(Y1, Y2). Assuming that (X1, X2, X3) are multivariate normal, with mean 0 and covariances as specified above, find the joint density function fyy, y,(91, y2). iii) Suppose Y3 =...
All questions and round to 4 decimals points please. Thank you! The bloodhound is the mascot of John Jay College? Suppose we weigh n-8 randomly selected bloodhounds and get the following weights in pounds 85.6, 91.6, 105.9, 83.1, 102.1, 92.5, 108.8, 81.4 Assume bloodhound weight are normally distributed with unknown mean of μ pounds and an unknown standard deviation of σ pounds. a) Calculate the sample mean for this data. b) Calculate the sample variance for this data.. c) Calculate...

Please solve ASAP, I only need the correct answer. (3 points) Find a particular solution to the system of equations x = -72x - 320y – 5e-8, y = 16x + 72y. Both of your functions must be correct to receive credit. x(t) = ((8/5)-5)^(-8t)-4e-(8t)-25t*e^(-8t) y(t) = e^(-8t)+e (8t)+5te^(-8t)

Please help me out with this question, correct answer only, need it ASAP, will give good feedback !! Thank you ! 2. A system consisting of a free particle is described by (x,0) A for -a < a and zero for all other , where A and a are late the width of the probability density about its mean value in position and mo- mentum space. Do these widths indicate that the Heisenberg Indeterminacy Prin ciple is valid for this...
