Official MATH discussion doe US -November

<p>Anyone else remember any other math questions? I’m particularly worried about the grid-ins 14-18.</p>

<p>For anyone who wants to know, the experimental math section was the 25-minute section that had the question that went something like this:</p>

<p>The area of the square is k, find the area of the shaded diamond in terms of k. (The answer I put was k/4, though that doesn’t really matter since the section was experimental)</p>

<p>^No it was not. I had experimental writing and I had that question.</p>

<p>^ yeah, that was a real section hahaha. The answer was like k/4.</p>

<p>I felt like i did better on the math this tome compared to the last time i took it.</p>

<p>I kind of wish that I would’ve had the balls to answer the few that I knew. I.e. : the question about Mary and the trip. I worked it out and got 8/3, but it seemed like it was too easy, so I skipped the question.</p>

<p>I really hope the section with the pentagon question was experimental. >__></p>

<p>Yeah I got 2.67 for that one I think.</p>

<p>@Haphazard Wasn’t that one a grid-in? Even if you get the grid-in ones wrong it counts as an omit, or 0. You should always guess or put something in the blank if you have somewhat of an educated guess, since it’ll count as an omit anyways.</p>

<p>Can someone confirm these?</p>

<p>Points (3,3) (5,9) and intersects x-axis (i think) at 2?</p>

<p>And the similar triangles grid in? Was that like 3/2 or something?</p>

<p>@Ihateyouall Correct. The slope of the line was 3, or 3/1 (rise/run). Thus, (3-1, 3-3) = (2, 0)</p>

<p>And the similar triangles grid in was 1.5, or 3/2.</p>

<p>Awesome! At this point, I only missed that one about the area of the parallelogram one :D</p>

<p>Thanks! Wow I’m catching lucky breaks on this test</p>

<p>DANGGG i thought the one about the line was the y-intercept…rats…what do you guys think the curve will be for 1 wrong this time?</p>

<p>I don’t have 15 posts but I’m almost sure it said x-axis. I noticed it at the very last second lol</p>

<p>Yeah I got (2,0) also. If you drew it out, it looked like the point would be very close to that anyway.</p>

<p>:( Awww i put -6 cause I though it was the y-intercept. what a stupid mistake!</p>

<p>kristen- I put -6, too, because I thought that same thing you did…i thought it was (0,t) so you had to find the y…</p>

<p>Heheh. It’s not about using your calculator too much, it’s about figuring out how to use your calculator as much as possible… Instead of doing the work used linear regression to find the intercept instead.
Series problem… Calculator does it as well.</p>

<p>how did you guys solve the pentagon problem? i had a hard time with that</p>
