If the numbers after the decimal terminate, yes, it's rational.
9.521521521 = 9,521,521,521 / 1,000,000,000
If they don't terminate, but the pattern continues (which I suspect is the case here), yes, it's still rational.
If <em>x</em> = 9.521521521…, then
1000<em>x</em> = 9521.521521521…
Subtract <em>x</em> from this to eliminate the fractional part:
1000<em>x</em> - <em>x</em> = 9521.521521521… - 9.521521521…
999<em>x</em> = 9512
<em>x</em> = 9512/999
If they don't terminate, but the pattern does <em>not</em> continue, meaning the next few digits could be something random like
9.521521521<u>19484929271283583457</u>…
then the number would be irrational.
Answer:Division POE
Step-by-step explanation:
Honestly, I would go with:
C. Yes, because the mean is larger in the math book
Because the mean for the math book is 49.9 and the poetry book's mean is 41.5. And since 49.9 is a bigger number than 41.5, that is why i'm going with that one
But it's for sure one of the bottom 2
Hope this helps!! :-)
