PSAT 2010 Wednesday Math Discussion

<p>Careless errors = death</p>

<p>Yeah i know right? Also, this is just speculation, but my student handbook practice psat seemed to have pretty decent curves and I found that the curves seem to correspond fairly well with the test(s) that year. So if anyone is curious:</p>

<p>M
-0 80
-1 77
-2 74
-3 71
-4 69</p>

<p>I know, right? Just finished a practice test where I accidentally left a zero off the end of one of the grid-ins… <em>facepalm</em> 77–oh-so-tantalizingly close to an 80!</p>

<p>National Merit Semifinalist Here saying that math makes very smart people QQ because of their own stupidity -_-</p>

<p>Hey is Ti89 allowed???</p>

<p>^Yes it is. I plan on using it tomorrow.</p>

<p>Alright. Cruise control ;)</p>

<p>I used my TI89 today!</p>

<p>Math was extremely easy today. </p>

<p>I made one careless mistake on the grid ins >.<</p>

<p>yea, the TI-89 is allowed because it doesn’t have a QWERTY keyboard. I use it because it’s so cheap and saves time. I have to admit that people with 89s have an unfair advantage though…</p>

<p>What I remember:</p>

<p>Month #4
26 x 26 x 10
1/5
slope was 5/7
.35 is in between .3 and .4</p>

<p>All agree?</p>

<p>Yes.</p>

<p>Also, for the one about triangles with the answer of 25, was that letter C?</p>

<p>^^What was 1/5 again?</p>

<p>1/5 was the one where it gave you 5y=x(root5) or something…</p>

<p>Perhaps you mean 3/5?</p>

<p>I don’t remember the slope question, but I believe I got the same answer. Basically you switch x and y for the two points and solve for the slope, yes?</p>

<p>There is very little that an 89 can do that an 83 or 84 can’t for the SAT. The factoring and solve functions are almost useless on the SAT - nothing you can’t do with the y= button on an 83 or 84. As for some basic stuff the 89 can do (eg: simplify radicals), there are programs written for the 83 and 84 that do the same thing. Trust me, I’ve taken many SATs and SAT practice tests and the 89 doesn’t really supply you with much of an advantage.</p>

<p>i got 25 and 5/7 slope.
it was 1/5 rt(5)<em>rt(5) over 5</em>5 so 5 over 25</p>

<p>THe answer was definately 1/5s</p>

<p>Instead of switching x and y for transforming across x=y, I used the opposite of both numbers. -7/5. <em>Quits math team</em></p>
