<p>**Yeah.. It was like 2-3 red balloons, 2-3 blue, 2-3 yellow, 1-2 green</p>

<p>You do this:
2R (you can add 2 to this) | ---- 3R | ---- 3R | ---- | | ---- 3R
2B (you can add 2 to this) | ---- 3B | ---- 2B | ---- | | ---- 3B
2Y (you can add 2 to this) | ---- 3Y | ---- 3Y | ------ 3Y | ------- 2Y
1G (you can add 1 to this) | ---- | ----- 2G | | ---- | ----- 2G</p>

<p>3331
2332
3322
3232</p>

<p>4**</p>

<p>The one with the graph and how many times the line y=1 intersected the |(f(x))| i'm pretty sure was 6.</p>

<p>One with the 6 boxes and the 7 in the 4th box: 7
One with 56th step in the pattern: you make a graph of like 5x+8 on ur calc and go to 2nd > table, and go down to 56..</p>

<p>(a/b) - 1 = y</p>

<p>that answer turned out B/A + A/B = ? It was 2, right?</p>

<p>And the one with the bounded parabola:
II was F(X) < Y, when the graph is initially: F(X) = Y, and every answer but "None" had II in it. So it was None</p>

<p>8/3 or 2.666666</p>

<p>polygon answer was 11</p>

<p>what was the polygon question? </p>

<p>i agree w/ you on everything else! :)</p>

3

<p>i drew pictures for the first one the first time adding it up i circled, then i did it another way in hearts, then i did it another way in squiggly and then i did it in diamond around the numbers. weird but thats how i got 4!</p>

<p>haha and i think your talking about the 56th one or whatever with like a - number in the beginning and you get the number, i no lie, sat there and added it each and everytime until i got to the # and it came out right. </p>

<p>i do math the retarded way.</p>

<p>and i probably skipped the pollygon one because i can't remember it.</p>

4

<p>Polygon one was 11. It was like... somepolygon has sides less than 1 meter and a total perimeter of 10. What's the least number of sides it can have.... it has to be 11, no doubt.</p>

5

<p>Was the average (arithmetic mean) one = 7.5?</p>

6

<p>It was 7. 10char</p>

7

<p>I think it was just seven....... what was the 8/3 one???</p>

8

<p>don't remember</p>

<p>85 for an angle right?</p>

9

<p>Yeah something like that.</p>

10

<p>for the A/B -1 = y one, was it a multiple choice or grid in??
i hope i put 2...but somehow i feel i put 2...errh.HOPE NOT!!</p>

11

<p>And the one with the bounded parabola:
II was F(X) < Y, when the graph is initially: F(X) = Y, and every answer but "None" had II in it. So it was None
^ there's some debate; it stated that the point was in the interior, so a lot of people put II and III and it seems very reasonable.</p>

12

<p>It's definitely II and III; however, I really don't think the definition of "interior" used in that way should be tested on the SAT -- a "basic reasoning test."</p>

13

<p>It's II and III just because it said interior. If it didn't none of them would have worked because the equations wouldn't check out if it could be on the lines.</p>
