Unformatted text preview: Roughly, As = 55 to 60, Bs = 49 to 54, Cs = 43 to 48, Ds = 37 to 42. This is just an advisory (unocial) scale; Ill give you more info on the scale as the term goes on, and decide on the ocial scale after the nal exam. 1) The solution set is S = { (3, ,2) } . You should use this same notation, or something pretty close. I suggest checking your answer (eg set = 0 and check that (3,0,2) works. Then maybe = 1). The RREF (without the vertical line) is: 1 1 0 3 0 0 12 2) The trac diagram was on the board and had only two intersections. The rst showed IN = x 1 + 230, and OUT = 150 + x 2 . So, the rst equation is x 1x 2 =80. Similarly, the second simplies to x 2 = 130. So, x 1 = 50. You can stop there (youve solved it), or you can write S = { (50 , 130) } , using the notation of problem 1. 3) FFTFT 1...
