<p>and K was four. And it definitely asked for K, because I remember looking at C, and freaking out about what it was asking for (maybe it's that they sound kinda similar, idk) and then I checked the question and it was definitely K.</p>
<p>i agree with that, i remember asking myself why C was given</p>
<p>I don't know w/e I'm done freaking out about questions till December.</p>
<p>Oops, mistake....k=4.....
Sorry--I misread somehow.
I don't know if it's right obviously but I def. put 4.</p>
<p>It was definitely asking for k. How did you guys do the Celsius question? it was increasing at a constant and decreasing at a constant, find the temp when it was 2:00. I ran out of time, but someone just told me to guess increments. I tried doing slope etc, but it didn't work. :(</p>
<p>^you find the slope (which is 2 degrees per hour), find the temp at 3 o clock (29 degrees), then subtract 2 because it's one hour earlier than 3 o clock, which = 27.</p>
<p>hey do you remember the answer choices to the question, "which of the following are correct if a and b are positive numbers and a / b > a x b "?</p>
<p>because i put '_ only' as an answer choice - i think i put III only because I found out that choice I and II both have counter-examples. For example, 1.5/0.5 > 1.5 x 0.5 and 0.8/0.5 > 0.8 x 0.5 ...and -0.8/-0.5 > -0.8 x -0.5..and so on because there are no restrictions for a and b (the question only says that 'they are NUMBERS')</p>
<p>I'm pretty sure it was '_ only' as the answer choice and that it was not II only. ANyone?</p>
<p>i personally got this one wrong, but... so many people said that it was II only that I think we just have to go along with the fact that it was II only.</p>
<p>well you know that b<1 which is ii. are there any examples that counteract that?</p>
<p>yeah it was two only. if you show me the exact I, II, and II i can show you the numbers that prove it. I dont remember what the exact statements were.</p>
<p>does anyone remember any more questions? i don't remember what the exact statements were. we went over most of the ones on the second section already; anyone remember from the 1st section?</p>
<p>do you guys remember what the answer was to the three digit number question?</p>
<p>Everyone at my school said it was 20, but I put 40.
Wasn't the third requirement "Any 2 adjacent number are different," which means "332" and "233" are both possible. Am I wrong?</p>
<p>so what I did was 4 times 5 times 2.</p>
<p>what did you guys get for this?</p>
<p>I got 20. I think the statement was closer to "no adjacent numbers are the same"</p>
<p>i got 20 as well, but i was freaking out on that question as well.</p>
<p>yep, 0.2 / 1.2 = 0.666... and 0.2 x 1.2 = 0.24 - now that's a counterexample, no? or am i wrong with the question itself?</p>
<p>the question was a / b > a x b, yes?</p>
<p>0.2 / 1.2 = 0.666... and 0.2 x 1.2 = 0.24 is a counterexample for I and II, i think.</p>
<p>I and II for that question are both wrong becos if you solve a / b > a x b (provided that the restriction is that they are both 'numbers' not 'integers' as stated in the question)...you arrive at the conclusion that a > 0 AND 1 - b^2 >0 or a < 0 and 1 - b^2 < 0 must be true in order to make the inequality true and this contradicts I and II.</p>
<p>my question was a / b > a x b the question or not?</p>
<p>arghh. i hate it wen i forget test questions. -_-</p>
<p>yeah the question was a/b > ab when: </p>
<p>i: a<1
ii: b<1
iii: b<a </p>
<p>i believe</p>
<p>and to student 91 if you solve it the way you did you know that the numbers must be positive (the question stated that) so therefore a>0 (which is a given) AND 1-b^2>0 so 1>b^2 so if B is positive it must be less than 1.</p>
<p>What about the question with the line reflection over the x axis and then over x=1?</p>
