Official November 4 SAT Math Thread

<p>It was x > 7.</p>

<p>For the ski team one, very vaguely, the number of people on the ski team =X, the number of people in the Outdoors club= Y. Everyone on the ski team is in the outdoors club but not everyone in the outdoors club is on the ski team. I definitely put the answer that stated there were more people in the outdoors club than in the ski team. X<Y</p>

<p>there must be more than 7 people in outdoors club</p>

<p>ach44 - I put that also, that there were more people in the outdoors club than in the ski team.</p>

<p>@ Madame and Gyros - But the must, without question, be more people in the outdoors club than in the ski club. If there is only 3 ppl in the ski team, it is possible to have excatly 7 ppl in the outdoors club. Does anyone remember the question more specifically??</p>

<p>well the question was worded like this:
there are 7 people in the ski team. apparently 7 of them are also in the outdoors club. x represents the total number of people in the outdoor club. we are all in the same page that outdoor club must have more people than the ski club. so what must be true about x.</p>

<p>One of the choices was X<Y. With X being the ski team and Y being the Outdoors club. In addition, Gyro's answer couldn't be correct no matter what the variable "X" is reffering to.</p>

<p>what about the one with 50 teachers, 24 read one magazine, 21 read another (i think one of them was Time magazine), and 12 dont read either. how many read both</p>

<p>maybe we have a different question ach44. did you remember about the 7 members in both the ski and outdoor team</p>

<p>Good question. i think my answer went like this,
1. 50-12=38 (Teachers who read)
2. 38-24=14 (Teachers who do not read the first magazine)
3. 38-21= 17 (Teachers who do not read the second magazine)
4. (24-14)+(21-17)= 14 (Total who read both)
I am not sure if that is right..</p>

<p>@ madame I vaguely remeber there being 7 in the Ski team, which would mean that there is more than 7 in the outdoors club. Which would make the answer:
1. Outdoors club has more than 7 members. Which is just another way of saying that the outdoors club has more than ski team, because the ski team has 7, which means that the number 7 and the total # on the "ski team" are interchangable values</p>

<p>nice.,,then i got it then</p>

<p>ach44, you're counting the number of teachers who read both twice. The answer is 7.</p>

<p>oops forgot to put the divide by 2 magazines.</p>

<p>i feellike there were more hard ones</p>

<p>the system of equations which was like</p>

<p>2x+4y=6
?x+?y=?</p>

<p>how many possible ordered pairs?</p>

<p>a) 1
b) 2
c) 3
d) more than 3.</p>

<p>anybody remember the second equation?
i believe this was on the same section as the r^2st=400 & rst=40 though, the tentative experimental for some of us.</p>

<p>(a/b)^3/2 is the correct answer</p>

<p>uhhh.... to what problem?</p>

<p>a^2<em>sqrt(b) / (b</em>sqrt(a) = (a^3/b)^(1/2)</p>

<p>NOT (a/b)^(3/2).</p>

<p>Better luck next test.</p>

<p>i don't think mathproblems took the test.
i've seen his videos on youtube, i think he's a big ol' indian tutor.</p>
