Determine the production vector x that will satisfy demand in an economy with the given consumption matrix C and final demand vector d. Round production levels to the nearest whole number..
Solution to last brainteaser Covariance of interactive regression Application: I run a regression of y ~ x (e.g., corporate bond spread returns on stock returns). Then I add an independent interaction variable I, and regress y ~ xI, x(1-I). To check the data, I look at the covariance matrix of.
Simplify each expression, and eliminate any negative exponent(s). (3a/b^4)^-1 (q^-1 r^-1 s^-3/r^-8 sq^-6)^1 Graph the function, not by plotting points, but by starting from the graphs g(x) = ln(x + 1).
show your work, otherwise there will be no points.
