Official SAT March 10 Math Discussion

<p>Well, grid-ins off the top of my head was:</p>

<p>4.N etc, answer = 4.6
X & Y tank capacity, answer = 6000</p>

<p>Lets continue the list but please name the question and what it was about and not just say the answer.</p>

<p>were there two different sequences and series questions? One had finding the sum of the 608 and 609 terms of the sequence -1 -1 0 0 1 1, which is -1. I think I saw another one about the 40th and 20th difference of another. Anyone care to enlighten me?</p>

<p>it was
1,4,7,10..
find the difference between the 40th and the 20th term
use the formula
a1 + (n-1)D
for both of them
then subtract
36's ur answer.</p>

<p>OMG, why is everyone caught up with useless formulas??? Like someone before me said, the difference between each term is 3! 3*12 = 36, you're done.</p>

<p>LMAO u guys will laugh at me but i just couldnt think of anything and i had a little time so I just made a big list with all the terms and i kept adding and adding lmao. Brute force at its best. Got the answer right though lol.</p>

<p>Btw it was between the 40th and 28th term.</p>

<p>ur righttttttttttt but i remember the forumla for a1N + C, c= A1- difference from precalc.</p>

<p>QUESTION they dont take off for wrong grid-ins.. right? thats what i was taught in my sat workshop.</p>

<p>No they dont, its only for MC.</p>

<p>Btw, for the take-off from the MC, when is it that counts, like, if u get two wrong, that is -2 and then -0.25(2) right? But what about if its 3 etc? Does it round up or down?</p>

<p>I heard that it rounds up!
Stupid College Board!</p>

<p>i think it rounds up. isnt that good though, tscogrady</p>

<p>So like if you get -1 in math, (just for example), so that is -1 - 0.25(1) = -1.25 So do they round that down to just -1 or is it considered -2, raw score of 52?</p>

<p>wow im retarded.have i been grading my stuff wrong this entire time in the workshop i went to? i thought u rounded after u subtracted it..</p>

<p>Does anyone remember if the 4.N question where N=6 was in the experimental section or not? I'm still trying to figure out which one was the section that didn't count :D</p>

<p>Thanks!</p>

<p>Ya i would like to know that too kathy_violin.</p>

<p>BTW, if someone could help me out in here, it would be greatly appreciated. Here are the 4 questions I missed:</p>

<p>1.) The one about taking Medicine A and Medicine B in a period of 6 and 4 hrs and when will they be taken at the same time again etc.
2.) It was like a set of numbers A={...} and B={...} and then it said to find the probability of A/B being an even integer/number.
3.) Find the biggest odd integer factors from like 56, 88 etc. (YES THIS IS STUPID!!! MAD EASY QUESTION!) oh well.
4.) The one about 2^-x * 2^y = 8 etc</p>

<p>Now, can someone tell me if any of those 4 questions that I missed were on the Experimental? </p>

<p>Because if any one of them were, I will have wet dreams! <--lol</p>

<p>Someone please? Thanks.</p>

<p>I'm almost sre the first question #1 (about the medicine) must have been experimental, because I don't remember any question like that WATSOEVER! But I did get an experimental math section, so is it possible that all the experimental sections are not the same (BTW, I did not get any section with drawings of chairs!)?</p>

<p>I do recall answering the three other questions, so if we did have different experimental sections, those 3 were definitely "non-experimental".</p>

<p>haha what WAS the answer to that question about the biggest odd integer after all?</p>

<p>Answer to biggest odd integer factor is D) 88</p>

<p>Also, i never got the question about the chairs either but i did get an experimental (4 math sections) so im just bound to think theres more than one type of experimental. So are you sure you didnt get the one with Medicine A & B? Thank god! lol I was just being a pessimist thinking all the ones i got wrong were on the parts that counted.</p>

<p>yeah the largest odd divisor was sort of weird. I stared at that question for at least 1 minute....trying to persuade myself that there was something to it that I was missing. But thank god I got it right! FEW! </p>

<p>And yes, I'm 99% sure I didn't have a question about medecine.</p>

<p>consolidated answers: (add if needed)</p>

<p>6
12
9
112
33
122
18
4.6
10/3
6000
A for the box thingy
B for the map
60
III only
four dots reflected y=x
(3,5)
b=6
88
1/16a^2
4:5 ratio of y:z
x=4 for the parabola tangent to the x-axis
4pi
1,2,3,4 (four numbers) for the union
36</p>

<p>whats the B For the map, and b=6??? eh? and can someone explain the parabola tangent to x axis thing..........</p>

<p>Does anyong remember the question about the dots reflected by y=x?</p>
