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)

Sure, what's your question? Note that we volunteers on the Jiskha site are here to help you guide your thinking. So before you post, do a little research first. And include in your question, some idea about what you think the answer might be.

Managerial Econ
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 am not an accountant; so I tend to avoid questions that apply certain accounting principals. That said, concepts in most disciplines can be understood with simple common sense. Don't make things more complicated than they really are. Second, don't panic. Do a little ...

You need to provide more information here. e.g., what was the question that mary answered?

1) seems to me, "a 40% chance of rain" is already expressed as a probability value. 2) I get 3/16 also.

An EXCEL spreadsheet is very helpful for these types of problems. Just set it up. eg., the balance formula (no extra payments) is: B1 = (B0-P)*(1+.08/12)

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...

Last week, in big financial news, the Fed cut the discount rate, an expansionary monetary policy.

Maths
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 ...

First the denominator. There are 8*7*6*5*4*3*2*1 = 40320 ways the 8 friends could be seated. Now the numerator: There a 6 possible seats for Trevor (he cant have an end seat). For each of these 6 seats, the two brothers could be seated in 2 ways. (A on the left B on the right ...

economic system
"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 ...

Macroeconomics
If your are in a first-year macro economics course then... 1) yes government purchases can increase total income. 2) cutting taxes could achieve the same result, 3) But the tax cut would need to be larger because the tax multiplier is one less than the government multiplier. ...
