December 2009 Math II Discussion

<p>@ BMittman: The (0, 2) answer choice was an open interval question. I remember specifically. That’s why it messed so many people up. If it was [0, 2] I doubt so many people (including myself) would have tripped up on it.</p>

<p>Also (to BMittman) - to be perfectly honest - I doubt the College Board will throw that question out, so you shouldn’t worry. :slight_smile: I actually had eliminated the answer choices down to (-3, 3) and (0, 2), but picked the wrong one partly because I was getting tired and failed to read the question carefully enough, and because I happen to be unlucky/dumb like that haha. I see my error now; I’ll actually be upset too if you end up getting penalized because of my stupidity.</p>

<p>Ah, so I didn’t remember correctly. But I highly doubt College Board would intentionally word a problem to confuse people. Seemed pretty straightforward, imo.</p>

<p>@fledgling, for the frequency table, you had to find the value of x such that the average of all values was one of the counted values. What I did was make a rational expression with an “x” in both the numerator and the denominator that represents the average of all values. Once I simplified it, I graphed it on my calculator and plugged in positive x values until I got a y value that was one of the numbers on the left side of the table.</p>

<p>^ Ooh, smart strategy haha. Perhaps I should have taken Math Level 2 first while my brain was sharper… oh well.</p>

<p>Funnily enough, I have multiple friends who told me the same thing. Maybe the SAT Math 2 study guide should say “TAKE THIS TEST FIRST.”</p>

<p>^ YES. haha</p>

<p>Meh, but I was taking Lit as well, and since I was scared about its harsher curve I decided to do it first while I could still think properly. This is why taking more than one subject test can be somewhat detrimental to overall scores lol</p>

<p>Just more ways College Board discriminates, lol. It costs $87 to take 3 subject tests on 3 different dates, but only $47 to take them on the same day, so there’s an automatic disadvantage for economically challenged students and kids with really cheap parents. Now that I think of it, how the hell can a kid with ADD possibly do well on the 4-hour SAT I???</p>

<p>lol… I especially like how the CB defines itself as a ‘not-for-profit’ organization as opposed to ‘non-profit’. =P</p>

<p>If the questions asked for the interval that would satisfy x^2<4, wouldn’t (-3,3) be incorrect because x=-2 or x=2 is 4. That is not less that 4. So wouldn’t the correct answer be (0,2).</p>

<p>^ No… the question asked (I remember it now, yay!), “Which of the following intervals INCLUDES ALL the values of x for which this statement is true: x^2 < 4”. The values of x would be [-2, 2], but the -1 and -2 aren’t accounted for with the (0, 2) answer.</p>

<p>No danny, it asked for which interval included all values that satisfied the inequality. It’s all in the wording.</p>

<p>Oops, double post.</p>

<p>^ Haha nice use of repetition/emphasis. =P I wonder how many more people are going to show up here and argue about (0, 2) before this whole argument dies down…</p>

<p>EDIT: Oh, haha! Never mind…</p>

<p>It probably won’t die down until the scores come out…</p>

<p>How will the debate end? We never see the questions we get right or wrong.</p>

<p>I think you can if you pay to get the complete score report. Also, once the scores are final, nobody really cares. :P</p>

<p>I believe that r= q and not -q because it asked for what they distances were. Distances cant be negative so they were both the same</p>

<p>does any one rember da function table it was like this </p>

<pre><code> 1 0
3 bla
4 bla
5 bla
</code></pre>

<p>any we have to find sumthing </p>

<p>wat was da answer of it ??</p>

<p>@ Dark_Angel: It was 4. Look at the previous page (Page 26) for BMittman’s explanation of how he arrived at the answer.</p>

<p>Crazyman, in that question (r,q) was an ordered pair, not a distance. The problem included distance, but it asked you to come up with the coordinate, which can be negative.</p>

<p>If it was asking for the distance, then they wouldn’t have told you what quadrant the circle was in.</p>
