6071 is the only number. If N+23 is divisible by 22, then so is N+1 If N+47 is divisible by 23, then so is N+1 If N+73 is divisible by 24, then so is N+1 ...

Because if N+1=2*11*23*2*2*2 then N+73 won't be divisible by 24. Jeff http://www.yourmathguide.com ... From: cray <rayc98@...> Date: Mon, 02 Aug 2004...
It's a trick question. The men in white suits had come for him by that stage, and his son took over the business and sold the cakes for 75 cents each....
If N+23 is divisible by 22, then N+23-22=N+1 is divisible by 22. Similarly, N+47-23-23=N+1 is divisible by 23, and N+73-24-24-24=N+1 is divisible by 24. So N+1...
You need to include a 3 because 3 is a factor of 24. Also, only three 2's are sufficient because 2³, a factor of 24, will be a factor of N+1; you don't need...
The Least Commom Multiple (LCM) is calculated using the common and non-common factors with the highest exponent. 22 = 1*2*11 23 = 1*23 24 = 1*2³*3 So LCM =...
A cab was involved in a hit and run accident at night. Two cab companies, the Green and the Blue, operate in the city. Here is some data: a) Although the two ...
Say the Blue cabs were involved in 0.01% of accidents and the witness's reliability was 100%, and not 80%. Then as long as the witness is telling the truth the...
I think you can certainly consider additional data when it's available to modify a probability estimate. We know there's going to be a substantial number of...
The second argument sounds similar to what I heard in a stats class once. "Isn't it just a fifty percent chance it rains? I mean, it either does rain or it...
There are a whole host of mitigating factors as to whether or not it will rain. When did it rain last? Is it raining anywhere else? Where in the world are we...

I was reading up on higher dimensions and some theorems, and I came across something that I've read before that I think might be false. I read that objects in...
