Devise an inverse transformation that converts the U(0,1) into a beta with parameters alpha, beta. I need help on figuring out the formula which I will then put into excel.

Start with a random number from the uniform(0,1) distribution.

And then thaws out again?

There's a project starting in May 2008 in a lab in Switzerland where they are going to try and test this theory. Some say that it may create some kind of black hole or something to where it will be possible to destroy Earth and possibly the entire universe. But, since it's never happened, no one really know what it will do. Just dandy, if you ask me.

Let f_n be a sequence of real valued functions that converges on a set X (it can be a subset of R^n, or any metric space) to a function f. Suppose that

(a) The sequence f_n is monotonic (the sequence, not the functions)
(b) X is compact
b) The functions f_n, n=1,2,3... and f are continuous

Show that the convergence of f_n to f is uniform on X.

Thank you for our help

two satellites (same masses) orbit round Earth in radii r and 2r (from Earth's center). The closer satellite experiences force of gravity (F). What additional force (Fo) need to be added to force of gravity experienced by farther satellite so that both complete one revolution in equal amount of time.
find F0 in terms of F?

Hello,

I have two bases (NAHCO3, NA2CO3) and an unknown monoprotic acid. I'm supposed to find the H+ concentration (so, pH, really).

How can I find the pH of this? I have Methyl Red available, but that's it.

What can I do to find the ph??!
