Let θ1 , θ2 , w1 , and w2 be independent standard normal random variables. we obtain two observations, x1=θ1+w1,x2=θ1+θ2+w2. find the map estimate θ^=(θ^1,θ^2) of (θ1,θ2) if we observe that x1=1 , x2=3 . (you will have to solve a system of two linear equations.)

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
