Mathematics - 15 July 2007

...including every sized square? That means 1by1 squares, 2by2 squares, 3by3 squares. I know there is not 64 squares since that would only account for all the one by one squares. I also ask for a formula that will help you find the number of total squares for any n x n chessboard.

I've been asking about thuis thing quite a few times, but I don't get usually get good answers.

Basically all I ask for is how to do the following and when do we use them?

standard deviation,

variance,

confidence interval,

density function,

binomial distribution,

normal distribution.

Also, if someone would like to teach me probability, it would be greatly appreciated.

Please explain thoroughly.

i know that you subtract and if the #'s cant cancel you multiply by a # to make it = to the other # but i just cant figure out this one problem =/ yikes!!!

(-1)^(n+1) ln x /n^2 tell if converge conditionally, converge absolutely or diverge

I have been trying to use all the rules an tests to see if ln n / n^2 is convergent or divergent and can't get it.
I think the limit of it =0 so nth term test doesn't work. The ratio test didn't work for me either. Can I use the p series test? or the nth root test?

If it does converge how do you know if it is conditonally or absolutely?

determine whether each pair of lines is parallel, perpenicular, or neither. If they intersect, find their point of intersection.

y= 4/3x -5
y= 3/4x + 2
my answer: the lines intersect and the point of intersection is (12, 11). please tell me if my answer is correct or wrong. and if you can please explain.

how do i determine the equation in slope intercept form for a line with endpoints (-5,8) and (8,2).
i think the y intercept is (0,6) but i cant find the slope.
