<p>No, not at all. I remember it said Math Level 2 on the cover. (I always check.) This is very worrisome. Maybe I got a past edition of the test or maybe even a future edition? How would this be scored?</p>
<p>do the proctors check the calculators for programs before the test starts?</p>
<p>I think it depends on your test center
But everytime I took the SAT they just came around to see if you have an appropriate calculator, they never once opened up my calculator and checked my programs, (not that I have any)</p>
<p>Can anyone shed some light on this </p>
<p>for the 3 trig functions
sin2xcsc2x
2sinxcosx
and the root one</p>
<p>if you plug in pi/4 into the second equation it equals one.</p>
<p>I read it as is there an x value in this set that makes the equation equal one.</p>
<p>Why would it ask if it is always 1 and give us a set to choose an x from??</p>
<p>btw sorry for reposting.</p>
<p>I am pretty sure the second one was 2sinx + 2cosx</p>
<p>sorry but i am 100% sure it was 2sinxcosx cause i remember it being the expanded form of sin2x which would equal 1 when x = pi/4…</p>
<p>i dont know but when I plugged pi/4 i deff did not get 1 for the second one… </p>
<p>two other questions:</p>
<p>the one where x approaches 2, the function gets closer to zero right?</p>
<p>the one were f(x) is define is only at (-1)… i think it was somthing like (?)/(x-?)(x+?)+4</p>
<p>what was the probability of picking a multiple of 3 or 5 from 1-30?</p>
<p>i just need to varify that the question asked for AT LEAST ONE value in the set that makes that equal one. If so then I am correct and it is answer E which is I II and III are correct as opposed to D which is only I and III.</p>
<p>@xs0it it approached 5 b/c the x-2 was canceled </p>
<p>@commodore the probablility question was something like 7/15.</p>
<p>For the I, II, and III question about which inequality is greater than 0 for any real x, I put none because they all had to = 0 at a certain x. Did I miss something? :(.</p>
<p>Currently, I missed the r/q, the frequency of the sin graph, and the equidistant points on a loci. Can someone explain that one to me?</p>
<p>The intersecting one was perpendicular b/c you could just draw perpendicular lines… haha what can i say, draw some intersecting lines and see for yourself. The OTHER I II III question with the >0 was the last one because at no time did it equal or go less than 0 the other 2 at some point equaled 0 which would go against the question</p>
<p>also, just curious, look at post 304 and what did you get for that question/why and the discrepancy is on post 309</p>
<p>I drew a rectangle, 2 intersecting lines (skewed and perpendicular) and couldn’t figure it out… it was awkwardly worded to me :(.</p>
<p>Did III have imaginary roots? I just glanced at them quickly and put None.</p>
<p>For your question, it said: Which of these =1 for all values between 0 and pi/2. The first and last reduced to 1, but the 2nd was a double angle: Sin2x, so it didn’t work.</p>
<p>dang… thats -6… 800 hanging by a thread. The curve will determine everything…</p>
<p>I dont think III had imaginary roots, just never went to 0 or under.</p>
<p>for the r/q one, was there one option that said q and one that said -q? I didnt even see the -q one. </p>
<p>i got 8/15 as the probability idk.</p>
<p>8/15 wasnt a choice?</p>
<p>but it was 100% 7/15 anyway</p>
<p>Did you guys get E for that one question that asked if the graph should move pi/2 units to the right?</p>
<p>Question 36ish, the one with 3x-2 function equaling x: (x-2)/3 (Choice E)</p>
<p>-Question 41: 3 (Choice D) – still unsure if this is right but others say it is</p>
<p>-Question 42: 5.82 (Choice E) - with the 2 triangles</p>
<p>-Question 45: Statements I and III were true (3 trig functions and it said which ones equal one always - answer that didn’t fit in was 2sinxcosx)</p>
<p>-Question 50: 2 (Choice B?) - used gauss jordan</p>
<p>-Question that had the table of frequencies and had the frequency of 4 equal x — that should have been “x = 4”</p>
<p>-Question that said the center of the circle is at (0,6) — I said -8 and 8</p>
<p>-Question that said “if 14 and 10 are removed from a set of numbers equaling 240, then what’s the remaining average … blablabla” — the answer was 21.6</p>
<p>-Question that asked the frequency of the sine graph — freq was 1/pi</p>
<p>-Question with probability - 7/15</p>
<p>-Question about what doesn’t change - standard deviation</p>
<p>-Question about r and q thing - negative q</p>
<p>-question with weird function: (0, z, 0)</p>
<p>-Question with someone driving and someone else driving to catch up: (Choice A) abs(10t-60)</p>
<p>-Question with geometric sequence: n^2 + 2</p>
<p>-Question with 2 lines and they asked what are the points equidistant (loci): 2 perpendicular lines </p>
<p>-Question with plane and asking the # of lines perpendicular to one line - The answer is “infintely many” </p>
<p>-Question with a limit as x approaches 2. Answer - 5</p>
<p>-Question with “a” = ax -2 or something like that, it was “2” for the answer I think</p>
<p>-Question with sin graph shifting- it should have been shifting to the right. (dunno what answer choice that was)</p>
<p>@Sunspark
Yes, I think I put that one.</p>
<p>Also, I don’t find most of the questions being disputed ambiguous at all.</p>
<p>For the question with (3,-3), the question said:
“Which interval includes all of the x values that satisfy the inequality x^2<4?”
All of the values that satisfy the inequality are within (-2,2) and all of these values, clearly and definitely, are included in the interval (-3,3).
All other choices, e.g. (0,2), left out values. This question didn’t have any discrepancies.</p>
<p>For the question with:
I. sin2xcsc2x
II. 2sinxcosx
III. sqrt((sinx)^2+(cosx)^2)
The answer was “I” and “III”. Choice “I” cancels out and becomes 1; choice III is obviously one. The second choice becomes “sin2x” which of course does not equal 1 for all values within the defined domain.</p>
<p>Grrr, I know for sure I didn’t get an 800 despite this being the second time I took the test. I’m just hoping my score is higher than what it was last time (760)…</p>
<p>EDIT: What would 4 omits and 3 wrong come out to be? A 780?</p>
<p>Is here anyone who had taken the October test too? This one felt significantly easier than that one, at least to me.</p>
