Lockheed Martin is increasing its booster thrust power in order to win more satellite launch contracts from European companies interested in new global communications markets. A piece of earth-based tracking equipment is expected to require an investment of $13 million. Annual operating costs for the system are expected to start the first year and continue at $0.9 million per year. The useful life of the tracker is 8 years with a salvage value of $0.5 million. Calculate the Annual Worth for the system if the corporate MARR is currently 12% per year.

For the regression model Y: = {5'0 + 6;. Derive the least squares estimator of 50 for this model and Prove that the least squares estimator of 30 obtained is unbiased. Consider the simple linear model, Y= a + B X + e with e~ N(0, 03) in zt=1xt2 0.2 ?=1(Xi-X)2 e usual notation. Prove that Var(a) = Let y= X B + e, where X IS an n>
