October 18 PSAT Discussion

<p>Choklit I think you’re right about the meerkats now that you mention it… I remember there being something like “as” instead of “and” or something?</p>

<p>And yep 4pi r^3</p>

<p>Yeah, I think the although one had the ‘as’. I remember something like that. Does anyone know the linking word between the two clauses? Or was Meerkat the first subject?</p>

<p>I’m sorry for my spastic nature. They should do a reading passage on me.</p>

<p>I think that the Meerkat sentence was something like,
Standing only one foot tall, even when on their hind legs, meerkats are carnivores that feed on plants and small animals.</p>

<p>what about the math question that was asking for the formula of number of cells if they double every half hour for n hours? i think i put 2n^2n, if i remember correctly. </p>

<p>i tried to write it out with a chart, but i couldn’t really get it so i guessed. what did ya’ll get?</p>

<p>sopheng I got 2^2n for that I think…</p>

<p>and for the 4(pi)r^3 that was E right?</p>

<p>speaking of “as”, wasn’t there a writing q where you had to change “as well as” to “but also”. I think it was in the identifying sentence errors section.</p>

<p>^yup I remember that it was like not only…but also</p>

<p>it was 2^2n…the exponent had a 2n in it accounting for the half hour, i think</p>

<p>^ yeah it was every 30 minutes but you had to express it for every hour it had to be 2n…</p>

<p>I concur with 2^2n.</p>

<p>I don’t remember the “as well as” sentence, does anyone know the wording?</p>

<p>And that sentence sounds about right for the meerkats</p>

<p>Highopes, I think the sentence was along the lines of Not only__<strong><em>, as well as _</em></strong>__. Sorry, I don’t remember the subject of the sentence, but that’s why “as well as” is incorrect.</p>

<p>Okay so for the x > x^n > 0 question…
Where n is a positive integer, what is x?</p>

<p>Since n can be 1, this problem doesn’t work. And I’m going to send an e-mail to the test people because of that. (:</p>

<p>I think its asking for a possibility that could work given the following requirement, that doesn’t mean it has to work in all cases…</p>

<p>But that’s stupid.</p>

<p>If you plugged in a fraction, it doesn’t work when n=1…</p>

<p>What did you put?</p>

<p>Thank you for your confirmation on the Meerkat problem. I can sleep peacefully now =)</p>

<p>Well, not quite. That problem is odd! I think ETS will pull it out, possibly lower the scale.</p>

<p>EDIT: The odd problem referring to the n^1…</p>

<p>Does anyone remember the exact answer for the meerkats one? And how was the cone-shaped sentence worded? </p>

<p>I got a fraction for that one so I just bubbled in .5, but I realized when I got home that no number can work for that equation. Oh well.</p>

<p>1/2
But I don’t think there’s any real answer. That’s why I’m e-mailing the test people. (:</p>

<p>The cone shaped one had a semi-colon (blah blah lay eggs that are cone-shaped; such eggs…)</p>

<p>There is no need to e-mail the test people. The question said that n is a positive integer such that X> X^n > 0. Therefore if you use one then that inequality is not satisfied. If you use anything other than one it is. So by that reasoning you deduce that n is not 1. So any fraction less than 1 but greater than 0 for x will be correct.</p>
