Hummmmm, I don't think you want to do that! P=12.4-4Qd could be rearranged, using simple algebra, as Qd=-(P/4) + (12.4/4)

At equilibrium, Pd (price demand) = Ps (price supply), and that Qd=Qs. So, 12.4-4Q=-2.6+2Q. Solve for Q: 15.0-4Q= 2Q 15.0 = 6Q (15/6) = Q

I think I see what you are after here; I think you are trying to find the speed definition of "slow" 2 out of 150 is .0133. That is 1.33% of drivers are slow. Ergo, 1-.0133=.9866 are not slow. Look up .9866 in a normal distribution table (probably found in your stats...

I'n not sure I fully understand your question, but let me take a stab. The likelyhood of a care being warranted and registered is 80%*%90 = 72 = 0.72 Ergo, the likelyhood of having a problem is 0.28 So, with 50 cars you would expect to find .28*50=14 problem cars, with a ...

"appropriate" is a loaded and subjective word. Further, some government activities and programs could be widely viewed as appropriate up to a point. That said, we generally expect our federal government to: establish a monetary system maintain economic stability with...

1) No, 8.0 is the correct answer. 2) a strange and unlikely probability distribution. But lets go with the stated parameters. It states that ZERO percent of the population loses less than 6 lbs OR more than 12 lbs, but exactly evenly distributed between 6 and 12. The ...
