You will need 29.22 cans of paint, but since you can't buy .22 cans, it would probably round to 30 cans

jasenka [17]

<span> Yes, the total runs is a better indicator of wins because it has a stronger linear association. Total runs has a stronger linear association because the data points sit closer to the trend line than the data points on the home runs scatterplot.</span>

How do you factor r^8-1

Harrizon [31]

There's a simple factorization for the difference of squares:

$a^2-b^2=(a-b)(a+b)$

Here, we have

$r^8-1=(r^4)^2-1^2=(r^4-1)(r^4+1)$

But $r^4$ is another square, so we can do more:

$r^4-1=(r^2)^2-1^2=(r^2-1)(r^2+1)$

Not done yet!

$r^2-1=(r-1)(r+1)$

Putting everything together, we have

$r^8-1=(r-1)(r+1)(r^2+1)(r^4+1)$
