I want to find out if there's a correlation between a number of events (column one) noted 1, 2 , 3, 4 (as took place only once, twice etc) and a certain consequence (let us say death) having the number of subjects that went through that events (once or twice etc) as the second column and the number of subjects that suffered the consequence as column 3. What test to use?

a) Factorise
9x squared -4

b) Solve the inequation:

5x + 2 / 11 is less than or equal to 2

c) Convert 180 kmh^ -1 to ms^ -1

d) If each corner of a square is joined to each other corner of the square, two diagonals will have been joined. To do the same for a hexagon, nine diagonals would have to be drawn. How many diagonals would have to be drawn on a regular polygon with 15 sides?

If the "Mean Value Theorem" applies,

find all value(s) of c in the interval such that

f'(c) = [ f(-1/2) - f(-3)] / [ (-1/2) - (-3) ].

If the "Mean Value Theorem" does not apply, state why.

Brazil won world cup in 1994. Before Brazilian won world cup in 1970. If the figures adds up, result is: 1970+1994=3964. Germany won world cup in 1990. Before Germany won world cup in 1974. Look: 1990+1974=3964. Argentina won world cup in 1986. Before Argentina won world cup in 1978. And: 1978+1986=3964. Using similar accounts we can guess wo is world cup winner in 2002. 3964-2002=1962 in 1962 world cup won Brazil. Let's check when Russian will be champion! They have never won in world cup. It will be 0(zero). 3964-0=3964. Yeees!!! Russian will be champion in 3964!!!

1) Show that the sequence formed by squaring each term of the sequence a1,a1r,a1r^2,a1r^3, ..... is also a geometric sequence.


2) The numbers a,12 and b form an arithmetic sequence and b>a>0. If a+1,16,b+43, is a geometric sequence find the values of a and b

3) The sum of 3 numbers which form an arithmetic sequence is 36. If 1, 4 and 43 are added to each term respectively the resulting sequence is geometric. Find three numbers

4) If x, y, z form an arithmetic sequence show that 2^x, 2^y, 2^z form a geometric sequence.

The Age structure for Caucasians:
0-14 years old: 13.8%
15-64: 66.5%
65+ 19.7%

The Age structure for non-Caucasians
0-14 years old: 22.5%

I need to know how to put in the data points, how to get to linear regression, and how to graph it on the screen, please. The reason I'm asking is because my math teacher is only fluent with the TI 83, so I can't do any lin reg on my calc homework without borrowing a calculator.
