Mathematics - 25 July 2006

I am taking a statistics class. We are doing a presentation on how the TI-83 Calculator generates random integers. We need to come up with a formula or general rule on how the calculator comes up with the numbers. I know they aren't random, but I need to know how to get them myself.

I have a modeling agency really interested in me but first I need to loose 3 kilos. They say this after measuring my hips so kind of confused. I thought you convert it to pounds but my mom seems to think that it could be a few inches off my hips i need to loose.

It's a stair climber type exercise machine. Take a look:
http://i7.tinypic.com/210cac2.jpg

The length of the base is 30.25" and the width is 16.25", but the catalog does not list how high the foot pedals go.

Can you figure out how high the step is at the height shown in the pic, from the heel to the ground? And what formula did you use?

Thanks

Is there a difference when calculating independent and conditional probabilities?
Example: if A and B are independent, P(AandB)=P(A)*P(B)
but if B is conditional on A : P(AandB|A) = ? I think it's still P(A)*P(B)

I don't want to teach, and I don't want to take 7 tests to be an actuary, and I don't want to feel like I wasted 4 years of HARD work to make 35-40K a year. I have intern experince in an accounting dept. What can I do?

The positive zeros are obviously 2 and 4. But there is a third root as well, which is approximately equal to -0.7666647. However, I have not been able to obtain a closed-form expression for this number. The closest I have gotten is a proof that it is irrational.

Is there a closed-form expression for this number?

Like for example, you put:

Q. "What does" A "+" B "=?"
A. A * B
A. A + B [correct]
A. A * 10^digits(B) + B
A. round(A + B, 1 sigfig)

(Here I'm kinda using pseudocode.)

And it comes up with, partway through the quiz:

17) What does 37 + 25 =?
a. 925
b. 62
c. 3725
d. 60

I've actually seen something like this before, but I forget what it's called.

So far I've looked at something on elliptic curves, but my profs say that those are too advanced to do anything interesting with at this level. Any ideas? (Oh, no analysis please. Anything else is fine).

For example, with the limit (2-x)/((x-1)^2)...with x approaching 1, what would be the limit?

There is no summer math tutor available for summer courses at my college to ask these questions...I'm not just looking for homework answers. I appreciate any help, thanks!

Alright, so I have this massive assignment, and I've done most of it, but I need some major aid on these problems. I don't even know where to start, so if someone can show me how to do these, I'd appreciate it. Please show me your work, just leaving the answers won't teach me anything :)

I will use the letter "v" to symbolize a down arrow, as I don't know how else to type logs.

Write as a single logarithm, 3 log (x) - 4 log (y) -5 log (z)

Expand, using log properties, to get 3 terms, logvb(15m^2p)

Solve using the properties of logarithms

logvx^7=4

2logv5^(x) = 2 + logv5^(4)
