bromine or ((potassium chloride))

methanol (CH40) or ((Carbon Dioxide))

((pentane (C5H12))) or Decane (C10H22)

((fluroform(CHF3))) or Carbon Tetrafluoride (CF4)

iodine chloride or ((sodium sulfide))

hydrogen gas (H2) or ((Hydrogen Chloride Gas (HCI)))

Helium gas or ((neon gas))

((ammonia (NH3))) or nitric oxide (NO)

In my answers, ((____)) indicates my guess. I am kind of unsure of some of these. Let me know if I got any wrong.

Thanks to all!

The Team plays 36 games this year. At mid-season they won 16 games . How many of the remaining games must they win in order to win at least 80%of all their games. I know the answer is 13 remaining games cause i guessed and checked but i don't know how to set this up?

I bet their service would be the sh|t!! Can you imagine how crisp and clear the reception would be? They'd put everyone else out of service. I just thought of this because now Disney is in on providing cell phone service. Plus NASA could make a killing off of it. They could use the money to fund a mission to Mars, and then some. Imagine their cell phones too! They'd be so high tech. You think NASA will ever do it?

I've heard it does. I meant to find it's specific gravity and calculate it but I'm too lazy.

Suppose we want to integrate a function g(x) for a certain space D. Let I be the result of the integration.

Is it true that to get and estimate of I, one can do a Monte Carlo simulation by taking sum of g(Xi)/m where m is the total number of sample points and Xi are randomly sampled points from a uniform distribution in D?

E.g.

Say g(x) = x and we want to integrate from 0 to 100, ie D is 0 to 100.

We take say 6 points, 0, 20, 40, 60, 80, 100, assume they are points gotten from a uniform distribution from 0 to 100. so g(0) = 0, g(20) = 20, etc..

Sum them up is 0 + 20 + 40 +60 +80 + 100 = 300

Estimate = 300/6 = 50.

50 is the exact value of the integral.

The question is does this scheme work for every function g? Assume m can be extremely large, ie approaches infinity.

the mathematical answer would be an infinite increase. but for example, if we had no pimples and get 19 pimples how would we calculate the percent increase in these kind of real cases?
