Biotomic121, we still need a pic.  Your explaination made no sense at all.    

try looking here

Try looking through this :)

Thanks Heureka :)   

I'm confused but hopefully a little concentrated effort (of my own) will sort me out .  

What is an accumulator bet?

Do you need me to do it with the two points that you randomly chose?

Or can you work that out now.  

I used the proper regression line but the idea is the same and the answers should be more or less similar :)

Unless i have entered the values wrongly, Excel shows me that for 3 rebounds the expected height is approx 188.5cm

If i use the regression formula that Excel gave me

y=0.4063x-70.647

$${\mathtt{3}} = {\mathtt{0.406\: \!3}}{\mathtt{\,\times\,}}{\mathtt{x}}{\mathtt{\,-\,}}{\mathtt{70.647}} \Rightarrow {\mathtt{x}} = {\frac{{\mathtt{736\,470}}}{{\mathtt{4\,063}}}} \Rightarrow {\mathtt{x}} = {\mathtt{181.262\: \!613\: \!832\: \!143\: \!736\: \!2}}$$

It can't be 79, no one in the sample is that short :))

Thanks Chris,     

It was a great little problem :)

$${\frac{{\mathtt{48}}}{{\mathtt{100}}}}{\mathtt{\,\times\,}}{\mathtt{958.41}} = {\mathtt{460.036\: \!8}}$$

$460.04

180% of 820%

$$\left({\frac{{\mathtt{180}}}{{\mathtt{100}}}}\right){\mathtt{\,\times\,}}{\mathtt{820}} = {\mathtt{1\,476}}$$

1476%

How do I compute the yearly payment for a loan of $500,000 at 12% interest which is amortized over a five year period

You can do it with the present value of an  ordinary annuity formula

$$\\PV = C*\frac{1-(1.12)^{-5}}{0.12}\\\\
500000 = C*3.604776\\\\
c=500000\div 3.604776\\\\
Yearly\;Payment\;=\;\$138,704.87$$
