March 2012 SAT I Math Thread

<p>can someone confirm the c = 0 and r = 2</p>

<p>@drac</p>

<ol>
<li>For the n > 3, n is a prime, what are the factors, I got 8 factors</li>
</ol>

<p>Was this the one that was like p is a prime number greater than 3, what are the factors of 6p?</p>

<p>p = 5
6p = 30</p>

<p>30 and 1
15 and 2
10 and 3
5 and 6</p>

<p>= 8 factors</p>

<p>I put 4 because that’s how many PAIRS of factors there are.</p>

<p>brb gonna go slam my head into a wall</p>

<p>there were twice as many cats as dogs, so the answer was 28 cats. the sales of cars was 126. I think the shaded square one was less than 6400. or someother number I don’t exaclty remember…</p>

<p>for the factors problem i got 8. 5 * 6 = 30. 1, 2, 3, 5, 6, 10, 15, 30</p>

<p>I definitely had c=0 r=2.</p>

<p>One I would like to bring up again is the min/max translation one. The original f(x) had a maximum of 4 and a minimum of -2. However, I am pretty sure the question was asking the difference between the max of g(x) and the min of the original f(x). The new max for g(x) is 6 (translated up 2), and the original min is still -2, so I got 8 as the difference. Anyone else get that?</p>

<p>Also I think there was a fill-in one where the answer was 3, I can’t remember the question though.</p>

<p>@drac</p>

<p>if a prime number is multiplied by 6, then assume that the prime number is identified by variable p.</p>

<p>6 * p = 6p</p>

<p>Now how many ways can we dissemble this 6p?</p>

<p>1<em>6p
2</em>3p
3<em>2p
p</em>6</p>

<p>Yes, 1<em>6p and p</em>6 are not the same.</p>

<p>@gman45 </p>

<p>It was asking for the value between the max of g(x) and the min of g(x), which is why people here are thinking that the question was too straightforward. (which is also why I think the question was a trick question designed so that you think it’s asking for the min of f(x). I had to reread it 4 times to make sure I wasn’t imagining things.</p>

<p>yeah it said to include 1 and 6p</p>

<p>“I put 4 because that’s how many PAIRS of factors there are.”</p>

<p>same.</p>

<p>those of you who took march sat and jan 28 sat - which was easier/harder/same overall in each of the subjects math, reading, writing?</p>

<p>@gman45
The min also gets translated two units up.</p>

<p>@gman</p>

<p>I’m 99% sure it said the difference between the max and min of g(x)</p>

<p>Also the 6400 one was a large square with smaller unshaded squares inside right?</p>

<p>The indirect proportion graph was the one that looked like a backwards j right?</p>

<p>It may have been experimental but there was also one about four classes with four minute breaks between them. I said that the classes were forty minutes each</p>

<p>Was it pairs of factors or factors???</p>

<p>@msteiny1212
yes, it was the backwards j.</p>

<p>The other problem is prob exp.</p>

<p>It said to include 6p and 1? Are you sure? Ah</p>

<p>The inverse graph was the one that looked like half a parabola and was in Quadrant 1, right?</p>

<p>Still trying to figure out which one of my math was experimental, was the triangle def not experimental?</p>

<p>@msteiny1212</p>

<p>I’m sure it said to include 1 and 6p.
I’m also unsure if it said pairs of factors or factors. :/</p>

<p>Do you guys remember the really easy ones? I just want to make sure that those are right…I’m so terrified of careless errors.</p>

<p>Galinda - Yeah, I checked it by just graphing y=1/x on my calc.</p>
