<p>Guys, why is it that I remember (for the hotly debated (-3, 3) vs. (0, 2) interval question) that there was an answer choice that was (-4, 4)? Am I remembering things correctly? Because if I am, then (0, 2) would definitely be the right choice.</p>
<p>By the way, what were the other choices for that question? I don’t remember putting neither (-3, 3) nor (0, 2).</p>
<p>I omitted that question, but I think that the answer is -3 and 3 because all the values of x that satisfy x^2 < 4 fall in the set of -3 and 3. It makes sense to me now - I don’t know how I missed that question on the test.</p>
<p>@ DMOC/anyone else who’s reading this thread: please confirm whether or not there was a (-4, 4) listed among the answers for the hotly debated question. If there was, then (-3, 3) is not correct.</p>
<p>^ uhm, why would (-3,3) not be correct??? and i dont think there was a (-4,4)
the correct interval would have been [-2,2] and that fits into (-3,3) and (-4,4)</p>
<p>^ Right, but if (-4, 4) existed as one of the answer choices as well as (-3, 3), and [-2, 2] fit into both, then the question would probably have been been asking, “what is the interval over which all the values it covers would work?” or something like that, just so both of them would be eliminated… not sure if you catch my drift. </p>
<p>But either way, I guess I’ll take your word for it. This is certainly not the first time I was caught remembering something wrong.</p>
<p>Anyway, in regards to the multiple posts about submitting a complaint to CB: for those of you who sent something, did any of you actually hear back from them? It says on the CB’s website that they reply to written requests…</p>
<p>Almost positive it was (0, 2)</p>
<p>I sort of needed to post this to appease myself a little/predict my scores. </p>
<p>-Question 50: 2 (Choice B?) - used gauss jordan <em>OMITTED</em></p>
<p>-Question that had the table of frequencies and had the frequency of 4 equal x — that should have been x = 4 <em>probably INCORRECT, but I’m assuming the worst case scenario here. This was hotly debated earlier in this thread… I’m not sure which answer to go with unless someone shows me</em></p>
<p>-Question that asked the frequency of the sine graph — freq was 1/pi <em>INCORRECT</em></p>
<p>-Question about r and q thing - negative q <em>OMITTED</em></p>
<p>-Question with 2 lines and they asked what are the points equidistant (loci): 2 perpendicular lines <em>OMITTED</em></p>
<p>-Question with plane and asking the # of lines perpendicular to one line - The answer is “infintely many” <em>INCORRECT</em></p>
<p>-Volume of cylinder question <em>OMITTED</em></p>
<p>-Interval question with (-3, 3) vs. (0, 2) <em>INCORRECT</em>… unless that complaint thing goes through, and I’m not sure if it will. I’m going to go with the worst case scenario though. </p>
<p>Bleh, worst case scenario for me is 4 omits and 4 wrong answers. This brings my raw score to a 41/50… ugh! Either a 770 or a 780 I’m guessing?</p>
<p>Can someone please tell me what was question 50?</p>
<p>Questions I got Wrong:</p>
<p>Frequency of the Sine equation</p>
<p>Complex Roots Cubic Equation</p>
<p>Perpendicular lines, loci </p>
<p>That question on the points the line goes around (-8,8) </p>
<p>that -3,3 vs 0,2 question</p>
<p>Plus i omitted two</p>
<p>plus i bombed my physics SAt 2
**** my life</p>
<p>
</p>
<p>It asked what was the point value for the test scores in the second column.</p>
<p>I created a 3 x 4 matrix in my calculator and came up with 2 for the answer.</p>
<p>There wasn’t an answer with (-4,4) and there was the word “include” for sure because I double checked after I thought the question didn’t have a correct answer.</p>
<p>I couldn’t remember the exact wording of the question of the -3,3/0,2 question. But I tried asking my dad, a math professor, it and he said if it said “satisfies” then 0,2 would be the answer. Otherwise, -3,3 is the correct answer.</p>
<p>BTW -4,4 was not a choice. (-3,3) was the only choice that was inclusive of (-2,2).</p>
<p>yup…I put (-3,3)</p>
<p>Ugh, yeah, the answer was definitely (-3,3). That question tripped me up so much.
And I’m pretty sure one of the other answer choices was (-1,4), not (-4,4).</p>
<p>@sanxie: the same situation here…the question is not clear enough…</p>
<p>It was definitely (-3,3). </p>
<p>And I am 100% sure that (-4,4) was not an answer choice. There were three choices that contained part of the interval but not all of it, and then (-3,3). I’m actually shocked this question is so debated. I thought it was one of the easiest questions on the test. It specifically read “which interval contains all the values”, not which is the interval that contains all of the values and no other values.</p>
<p>Guys, if the problem you’re all whining about is asking what you all incorrectly think it was asking, [0,2] would be wrong by your interpretation, as well. All the intervals were closed, iirc, and the value x=2 wouldn’t satisfy x^2>4. </p>
<p>Once again, the wording was either “INCLUDES ALL” or “CONTAINS ALL” not “only includes.”</p>
<p>@Underdog, I agree. I don’t mean to sound like a selfish ass, even though I am, but if they somehow throw out that question and it messes up the curve for those of us who read carefully, I won’t be very happy.</p>
<p>@ sanxie: Oh, that’s right. (-1, 4). I knew I was most likely remembering something wrong. </p>
<p>Can somebody explain to me the reason why 4 is the correct answer for the frequency table? I probably got that one wrong too (I’m assuming the worst case scenario for everything), but it would be nice if I had an explanation so I don’t mess up again… </p>
<p>Hmm. Do you guys think a score of 770 or 780 is worth the retake? It’s only 10-20 points up from my previous score (760), and I was hoping for an 800, but things didn’t work out as planned.</p>
