Right exactly: I assumed uniform for choosing wrong answer. You're right: I should have spelled out that assumption. But after making that assumption, is my answer correct?

Haha, thank you! It may be totally obvious to you, but it wasn't to me, which is why I asked. Sorry for wasting your time.

Ah, thank you! I like your approach, and it'll reduce the number of numbers you'll have to square. 38^2 = 40*36 + 4 = 1440+4 = 1444 37^2 = 40*34 + 9 = 1360+9 = 1369 36^2 = (35 + 1) ^2 = 1225 + 70 + 1 = 1296 I can get those relatively quickly using the above method, the problem was that...

Thanks for your response! When I did it, I pretty much just figured out it was between 35 and 40, and then started squaring them one by one. What about my other question? Would you outline the method out loud as you were doing it, or just be silent for 5 seconds until you've figured out the...

I think it should be: 0.75 + 0.25*0.20 = 0.8. What are other people's thoughts?

For the mental math questions, are we expected to just rattle off the answer, or talk out loud through the steps? For example, -> Whats 54% of 110? ->(wait couple seconds to calculate) 59.4 or -> Whats 54% of 110? -> Well that's 54 * 11 /10 = 594/10 = 59.4 For the square root of...

The answer to this one is 13 11 13 But I can't figure out why? Any ideas? I know the arguments are pushed onto the stack in reverse order, but I haven't been able to figure out anything else. Thanks!

I'm treating (sqrt{2}) to the power of itself infinitely many times as the limit of (sqrt{2}) (sqrt{2}^sqrt{2}) (sqrt{2}^sqrt{2}^sqrt{2}) ... What does this sequence equal? I'm not convinced that it equals 2, we can show that it equals 4 depending on how we group them? Anyone know if...

1. The answer should be 0.5. If the jerk picks his own seat, then the last passenger clearly gets his. If the jerk picks the last passenger's seat, the last passenger clearly can't. If the jerk picks any other seat, say that of the Mth passenger, we can shrink the problem down to an airplane...

I have a question regarding this. Sorry I don't know how to embed the Math properly. If I have x^x^x^... = 4 Then by your logic, x = (4)^(1/4) = sqrt(2) also. So x^x^x^... = 4 = 2? How do I even know that the infinite power thing even converges? Thanks!
