March 2012 SAT I Math Thread

<p>Can anyone give me an in depth explanation for the question that dealt with f(c) and g(r)? (the one with the chart of values) I didn’t know how to approach that problem … what exactly was it asking and how did you approach it?</p>

<p>-3 or 4. Will that still land me at 700+?</p>

<p>@Tkaler1… yes -3 or -4 will most likely leave you at 700+</p>

<p>I GOT THIS QUESTION!!! and the one after it had something to do with (pie)(x). 1/4950 is correct. its 98!<em>2/100! or if your calc overloads: 2/(100</em>99). I omitted 19 and 20 on that section so hopefully its experimental.</p>

<p>but didn’t it say BETWEEN 100 and 200 which would exclude 100 and 200 to make the answer 27???</p>

<p>No it was definitely inclusive.</p>

<p>@hockeyshark no, the question was 100% inclusive.</p>

<p>If I put 5.6 as the answer to the point one, would that be counted wrong?</p>

<p>Did anyone else get 8/15 for the cake question?</p>

<p>yes, 8/15 was correct</p>

<p>I believe it was actually 4/15, since you had to deal with the whole cake.</p>

<p>Anyone feel that the math section was the easiest on the march sat? And also how did you get 8/15? I was getting like 1/15 I think.</p>

<p>What do you guys think a - 3-4 would be? After reading the responses I’m not so sure about my answers…dan I hate the sat.</p>

<p>@ Golfer0210
I think your right…I forgot to account for half of the cake when I added the fractions darn…</p>

<p>Yeh I wrote down 8/15 then when going back and rereading questions in an extra minute I had at the end I was like “oh glad I saw that” and quickly changed it to 4/15.d</p>

<p>who else is tired of waiting for their score?</p>

<p>Okay, It was 8/15 of the half, which comes out to be 4/15 of the whole, they asked about the whole, not the half. Also in the question about between 100-200, it literally said so,thing like “numbers between 100-200 inclusively.” it was made very specific that it was inclusive in the question.</p>

<p>I put 4/15. Something clicked in my head when I went back over my answers. “Wait, 8/15 is greater than one half of the cake. There is no way that kid ate that much cake.”</p>

<p>I can’t remember the question exactly, but there was a scatterplot question that asked something like, “How many of these data points are greater than 80?” There were a few points on the line of 80, so I didn’t count those. Is that right, to not count those that equaled 80?</p>

<p>Was the cake question a grid in?</p>
