<p>The answer is 5, simply because</p>
<p>When you count by 3 and 4 you have one left over.</p>
<p>I made a chart and everything.</p>
<p>no, the one about the stupid boy and the crayon</p>
<p>just2fitz, how would u make a chart?</p>
<p>Wait, what was the cut off number... like 27 or something?</p>
<p>ok.</p>
<p>so we know this:</p>
<p>X = 1 mod 4
X = 1 mod 3
X = 0 mod 5.</p>
<p>Does 5 = 1 mod 3? NO. Can 5 be the answer? NO.</p>
<p>Does 25 = 1 mod 3? Yes. Does 25 = 1 mod 4? Yes, Does 25 = 0 mod 5? Yes.</p>
<p>Is 25 the answer? Yes.</p>
<p>haha i put 25!!
i'm not sure but ive seen a lot of Q like this before
it always have OR and it usually mean BOTH</p>
<p>is 220~225 enough to get selected to anything?</p>
<p>depends on where you are, but i think in most states that's enough for semi-finalist.</p>
<p>logicus, dont you mean it to be
5 mod 3= 2
5 mod 4 =1
wrong, since both have to be one, but
25 mod 3=1
25 mod 4=1
so 25 is answer! all is good</p>
<p>myquestion is, y r u using mod like that?</p>
<p>when wil results be out? in december?</p>
<p>most schools get it in december, yet some choose to wait until after winter recess to give them to the students. i got mine around Dec 20th last year</p>
<p>only in computer science(afaik) is mod displayed as a binary operator in the way you used it(with %).</p>
<p>(to ilovemath)</p>
<p>In higher mathematics, it's typically written in the notation I used. Check mathworld for example.</p>
<p>the answer is ''25'' cause 3<em>8= 24 and 1 left over
4</em>6=24 and 1 left over.</p>
<p>so yeah answer is 25</p>
<p>it cant be 5 because 3*1=3 and thats 2 left over when the question says that its only one left over</p>
<p>im thinking if ETS would tell us the curve for this year's PSAT? im really desperate to know math's curve. -4 and 2 omit.</p>
<p>SENT!! I will tell u guys what they say tommorow - should be intresting =/</p>
<p>haha heres what I sent CollegeBoard. ->->->->->->-></p>
<p>hey i was just wondering, since the math was harder this year than last year, what will the curve be like? last year it was -1=76, -2=73, -3=70 and so forth. What will it be this year?</p>
<p>PS: I live in Mississippi and am a sophomore. Im positive I can become a national merit semi-finalist in MS because the cut-off is 204. But Unfortunately, were moving to Chicago this year and I will end up taking the PSAT as a junior over there. Sadly, I will have to make a 216 to qualify for national merit which I think will be way harder. SO, my question, since I've lived in MS for like 5 years, can I take the PSAT next year in Chicago and qualify for the NMSQT program by scoring in the MS cut-off range? As in scoring 206 which is good enough for MS but not enough for Chicago. I would really appreciate your feedback on this. Thanks.</p>
<p>Ok, about the question with the 3 or 4s:</p>
<p>Using logic and truth tables from Precal, we known that when we say "p or q", only one has to be true for the statement to be true, but both "can" be true. However, in this case, what happens if we reword the problem to "3 and 4"? How do you count by 3 and 4's? Alternating sequences, patterns? Count by 3, and then by 4? It doesn't make much sense. SAT would never ask such a tricky worded English convention problem as one of the first problems on the test.</p>
<p>Also, looking at past SATs, CB has NEVER asked a question with "or" that you can choose one of the conditions from several conditions that require it.</p>
<p>''SENT!! I will tell u guys what they say tommorow - should be intresting =/''</p>
<p>I would not expect such a quick answer. You may have noticed in the PSAT booklet that ETS does not answer via email. Questions are reviewed well after the test and "may" receive a letter. </p>
<p>In the case of the question about the counting by 3 or 4, I'm afraid that they will consider it a pretty clear case in support of the answer being 25. I won't add another lengthy explanation, but I cannot see the answer being anything but 25. Sorry!</p>
<p>does the cut off for the national merit stuff change every year?</p>
