OFFICIAL MATH IIc Discussion Thread [October]

<p>the w/h ratio median was B right? (the one that Julina said was .248)</p>

<p>second question for finding W was like C? i think the mean ratio was like .25 right?</p>

<p>Yeah, the first one was B. The second one…I don’t quite remember, there were 7 numbers that we had to find the average of…WAS it .25?</p>

<p>Edit: If it was .25, then the answer would have been like 12?</p>

<p>are you sure about the 30 / 75 % one?</p>

<p>i put in the equation and it said that at 30, y = .75</p>

<p>geddes, you probably didn’t square it…the equation was p = (t/(t+10))^2, the only number that works is 65. If you plug in 30 and square the result, you get (.75)^2 = .5625.</p>

<p>Julina- weren’t you supposed to find the H?</p>

<p>the answer should have been like a 3 digit number that started with a 2</p>

<p>it was like</p>

<p>A.) 2 digit number
B.) 2 digit number
C.) 2xx
D.) 2xx
E.) 2xx</p>

<p>it was either C or D if i remember right</p>

<p>I thought the December registration deadline was 11/07/06? That’s a few days after getting scores back, if everything works out correctly…</p>

<p>Actually, that makes more sense, if you were supposed to find H then I think the answer WAS 273 or something. </p>

<p>Johnnyboy, on my calendar (given by my school’s PTA), it says the December registration deadline is November 1st.</p>

<p>you got 273 right?</p>

<p>cuz i got something like that too</p>

<p>I just checked CB, they revised the registration deadline for December. Now it is indeed November 7th - my birthday!</p>

<p>So, you’ll have time to get your scores back, and decide if you want to retake them! I know I won’t retake them, no matter what my scores are.</p>

<p>I’m not going to retake either, December is too late for Early anyway.</p>

<p>Where are you applying early to?</p>

<p>so does anyone remember what’s the second part of the equation (right hand) for xy^5-2x=???</p>

<p>OH! and what did you guys for the period of the graph? it was an integer right? like 2 or 3</p>

<p>It was 2</p>

<p>10 char</p>

<p>I didn’t answer the period for the graph one. I couldnt’ remember how to do that at all. that’s probably bad, isn’t it (it hasnt’ been discussed in any of my math classes since freshman year and i’m a senior now)?</p>

<p>it was too hard to do so i graphed it, but i’m not sure if i read the graph right</p>

<p>ranks i think i got 2 too, it was A right?</p>

<p>Yea it was prolly A, i just remember it was one of the first choices. </p>

<p>And all you really did have to do was graph, find 2 mins or 2 maxes and subtracts the x values from each other.</p>

<p>Yeah, the answer to that one was 2. I just graphed it, and looked at the difference between peaks (like what above poster said about finding maxes, and subtracting). I was just a bit too lazy for that ^_^</p>

<p>I remember I used two peaks: 2.48 and .38 or something to see that the period was about 2.</p>
