October 2010 Math SAT Thread

<p>Did the hallway question ask for the 20% of the total in all hallways, or just hallway B??? I thought it was 20% in hallway B…</p>

<p>Was the one with putting numbers into circles with dotted and solid lines coming out of the circles experimental?</p>

<p>the dice was 1/54
jwilliams93 explained it well</p>

<p>Yes it was 290. It asked for the total, not just the grade 9 students.</p>

<p>i think the hallway question asked how many total lockers were in hallway B</p>

<p>119 (C) was the color of green (blue,red,green,yellow pattern)
1080 average hours of studying a week (for school year studying chart)
8 sqrt 2 ?? distance between the diagonol of the four circles with points in center</p>

<p>jollybjolly, it asked for the total in hallway B, not 20% of anything… You’re wrong, and the answer is 290.</p>

<p>hold on I had 118? not 119? I had 8000 not 6000?</p>

<p>290? I had 225?</p>

<p>Proof: 45/225= 20%??</p>

<p>What was the slope? (forgot what it was asking) of line l that was 30 degrees?</p>

<p>

That’s a lot of hours in a week…</p>

<p>x/2? i guessed. im so bad at math.</p>

<p>agree with 290. both 8000 and 6000 were answers. 6000 was grid in. 8000 was computers multiple choice i think</p>

<p>it was x over root 3 iirc</p>

<p>I really, really need to know which one math section is the experimental lol…and 1080…there are not enough hours in a week for that haha!</p>

<p>the slope of the line for 30 degrees was rad 3 times x(over one, but not necessary)</p>

<p>i got d for the slope. it was like root 3x</p>

<p>whoops, lol. wasn’t the answer 1080 for one of the questions?</p>

<p>The dice question is 1/18, i am almost 100% sure.</p>

<p>hold on I had 118? not 119? I had 8000 not 6000? ( For the computers question)</p>

<p>290? I had 225?</p>

<p>Proof: 45/225= 20%?? 225= 100% of hall b </p>

<p>15 paperbacks</p>

<p>On the dice roll debate,
you are rolling 3 distinct die, thats why the total number of outcomes is 6^3. If order didn’t matter, the number of outcomes would be 216/3 = 72</p>
