PSAT math questions!!!!

<p>lol i think that's exactly what i did. that would be a 700 according to the scale on the official PSAT practice booklet.</p>

<p>"sorry to ask this for the zillionth time, but are you guys positive that the
radx + rady = 10 find a possible value of x+y had to be odd? (as in x and y had to be odd?)"</p>

<p>I'm 100% positive it did not, my friend. Do not worry. One person said it did a while ago in this thread and it caused a pile of uproar. It simply is not true. All the question wanted was a possible sum of (a+b). There was nothing after that in the question, it stopped there. There was absolutely no odd/even stipulation in that question. I think the only time odd/even was mentioned was in that one primes problem.</p>

<p>I remember this question because it was on the bottom of the page. The only way it could've is if there were two tests with different questions (because it ABSOLUTELY did not say it on mine)!</p>

<p>BTW, here's some other questions and answers I remember getting (many may have been mentioned already).</p>

<p>$250,000 for flower shop percentage problem (MC)
$5.50 for phone minutes charge problem (G-in)
Choice B for the geometry three circles problem (MC)
1010 for the divisiblity by 10 problem (1st G-in)
c = 1/6 for the proportion problem (G-in or MC?)
42 for the number line k to k^2 distance problem (k=7) (MC)
27 degree C for the temperature problem (MC)</p>

<p>all those were mentioned geester. Um, I'm 100% sure it DID ask for an odd. I checked with my friends (who don't even look at CC) and they all said it did. They didn't see it at first either. I have a friend who put 9 and 49 for this reason. I put 1 and 81. Those were the two workable answers. The idea that it asked for odd would not just sponteously arise. In fact, if you use logic in thinking about it, it's more likely that you missed it than a general consensus of people misread it.</p>

<p>How, then, did the question actually read, prospectiveMD? (To the best of your memory) Or perhaps there were different tests? I don't know how I possibly could've missed that... Do you remember how the question was phrased?</p>

<p>yeah, unfortunately I didn't put odd numbers. I don't know how I could have missed it (the odd thing is so many other people are also saying that they missed it. Not the majority, which is why I still believe that I got it wrong, but.. a significant amount).. but I guess I did.</p>

<p>Okay.....Let me end this dispute right now. My explanation is 100% right....</p>

<p>Q: sqrt X + sqrt Y = 10</p>

<p>If X and Y are odd intergers, what is the sum of X + Y</p>

<p>X and Y both had to be ood (49 and 9) or (81 and 1)..........their sum DID NOT have to be odd....X AND Y HAD TO BE ODD....NOT THEIR SUM....I REPEAT....X AND Y ADD TO BE ODD INTERGERS NOT THEIR SUM........</p>

<p>sorry to use so many caps, but i had to clarify this for all of you. Again, I am 100% sure my explanation is correct.</p>

<p>okay, now let's move on.....:)</p>

<p>eep! i was so sure that k=4 but now i'm second-guessing.. it did ask for k right?</p>

<p>It did ask for K.</p>

<p>If I got 2 multiple choice wrong with no omits what would my score be?</p>

<p>73 - 77, it depends on the curve.</p>

<ul>
<li>b=42 for that k, a, b problem</li>
</ul>

<p>prospectiveMD what problem was this? do you remembet?</p>

<p>hey "you'll see", no one is ever 100% right... im pretty sure you are right too, but isn't there at least a 0.000001% chance that collegeboard screwed up? my friends are half and half - half are yes definitely odd and half are, no way are you kidding? seems like a lot of people missed it on these forums too... and i would be sourly disappointed if i got something like that wrong... i usually don't miss math questions...</p>

<p>I'm pretty sure it did say odd. As in 100% sure that I read the word, 'odd'...</p>

<p>what was the answer to the 3 digit combination problem?
Digits can repeat, adjacent digits cannot repeat...</p>

<p>GPA: k, a, b problem was the one with the number line where a=k and b=k sqr - k. It said solve for b. </p>

<p>akati: answer was 20. 4 x 5 x 1. First digit from left had to be two. Second had to be one of 3, 4, 5, 6, 7. Last one could not be the same number as the adjacent number so 5-1=4.</p>

<p>oh alright, that was one of the easy questions</p>

<p>yeah answer is 20 akati. i actually wrote down all the possible combinations so prospective is right,</p>

<p>i put 1/6 for one of the gridins....i think it was a quesion with x/a = y/b what is a/2b + 3(x/y)....something like that...does anyone remember this question, and did you get 1/6?</p>

<p>"i put 1/6 for one of the gridins....i think it was a quesion with x/a = y/b what is a/2b + 3(x/y)....something like that...does anyone remember this question, and did you get 1/6?"</p>

<p>Yes, it was 1/6. And haha, funny about the "odd" dispute - one girl said it said odd the rest said no way there were no restrictions (this includes myself). (How could so many people miss it, there's just no way, I bet the ETS may've screwed up and the odd/even showed up on only some tests.) So crossing my fingers on that one... Hopefully the curve isn't too harsh in any event, my guess is it's 77 for one wrong, 75 for two.</p>

<p>i'm sorry but does anyone remember what the very last grid-in question was?</p>

<p>It gave you the dimensions of a rectangle box. You had to multiply the 3 numbers and take the cube root. Answer was 1.5, the length of a side of a cube with the same volume as the rectangle.</p>
