I missed this lecture, and I'm really ticked off about it. Apparently, diff. EQ's can be expressed in terms of a series. Using a very simple diff. EQ, such as y' - y = 0, please explain how you would rationalize this idea.

How do you find angle B in a triangle is the two sides a = 24 and b = 47 are give along with angle A = 36 degrees.

2006-06-26 06:02:31 · 13 answers · asked by amber j 1

A=1
B=A
A=B
A^2=AB
A^2 - B^2 = AB - B^2
(A+B)(A-B) = B(A-B)
A+B=B
1+1=1
2=1.

Coffee Bean taxes items that are consumed at their location, but doesn't tax items to go. Why do other establishments such as McDonalds, Jack -in-the-Box, etcetera not follow that process...i.e., are we customers paying taxes on to-go items that aren't being taxed to the corporations? If so, it is a huge rip-off to the states that aren't collecting revenue from the very corporations that are taxing us. If we are indeed paying taxes on items that aren't taxed, what can we do about it?

This question relates to "Gambler's Fallacy". For the sake of this question, please assume that by using basic strategy that the probability of winning any single hand of Blackjack is almost 50/50. In this scenario, I know that the outcome of any single hand is unrelated to the outcome of the series of hands that preceded it. However, can a single desired outcome be predicted over a series of future hands? If I am not mistaken, the odds of ALL the player's hands being losses over a future series looks something like this:

(1) Hand: 50/50 (0.5)
(2) Hands: 75/25 (0.25)
(3) Hands: 87/13 (0.125)
(4) Hands: 94/06 (0.0625)
(5) Hands: 97/03 (0.03125)
Etc....

If this is true, might one conclude that the probability of winning at least ONE hand in the next four consecutive hands, for example, is about 93%?

If this is also fallacious thinking, please explain.
