<p>I'm concerned about that permutations question... did anyone get that? 10 serial numbers?
I guessed 15! - (10!)/5</p>
<p>i got 5! *10!/5!</p>
<p>Oh yeah good point. I was only looking at the one on the top.</p>
<p>How about the question that asked how many years would it take to get $300 if you began with $100 at 4.8% interest per yer? The trap was "23 years." It would take a minumum of 24 years correct?</p>
<p>uhhh maybe it was that... my memory is a little off... but actually i think its 10!/5 because the 5! would cancel... so lets say it was 5!*10!/5? Does that sound okay?</p>
<p>joshb has got it. It was 5!*(10!/5!), which is just 10! when simplified.</p>
<p>yea its 24, since its compounded annually it wouldnt break 300 until 24 years</p>
<p>why was this test so damn easy compared to june?</p>
<p>Yes APM I got that....</p>
<p>So so far...
*** denotes unsure</p>
<ul>
<li>The plane with perpendicular line = 2 circles</li>
<li>how many years would it take to get $300 if you began with $100 at 4.8% interest per yer? = 24 years</li>
<li>*** 10 slot serial number, 5 letters, 5 digits. 5! * 10!/5!</li>
</ul>
<p>it was just like...
5 letters? so 5 <em>4</em>3<em>2</em>1
then 10 numbers
so 10<em>9</em>8<em>7</em>6 which is 10!</p>
<p>i agree with everything.</p>
<p>Why did I make this more difficult than it was? <em>sigh</em> alright so was 5! * 10!/5!....</p>
<p>was there another answer similar to this one? Was there an answer that was 5! + 10!/5...</p>
<p>What was the truck problem with the 60% chance to get textbooks and 40% chance to get calculators and you had to find out the probability of getting something (the percentages are independent of each other)?</p>
<p>Also what was the integer one with r, s, t, k?</p>
<p>I think the r, s, k, v problem thing was rs/10?</p>
<p>I plugged numbers in for the variables and computer the results.</p>
<p>Am I right?</p>
<p>I think thats it... was that choice E, then yes</p>
<p>I plugged in numbers and got D, which was </p>
<p>sv/ a number. (sorry can't remember).</p>
<p>I plugged in 600 for k, and that's how it turned out.</p>
<p>Yes it was E.</p>
<ul>
<li>The plane with perpendicular line = 2 circles</li>
<li>how many years would it take to exceed $300 if you began with $100 at 4.8% interest per yer? = 24 years</li>
<li>10 slot serial number, 5 letters, 5 digits= 5! * 10!/5!</li>
<li> r, s, k, v problem thing= rs/10</li>
</ul>
<p>Use 30 as previously suggested. You don't need to prove it in general, just find one number to satisfy the initial statement and work from there...</p>
<p>My responses, please correct if wrong.</p>
<p>The Sk sequence was 2^k-1
f-g(1) is negative when f(1)<g(1)
The truck problem was 0.76 (guessed)
polar coordinates one was E</p>
<p>Lets see which others I remember and someone okay them...</p>
<p>the composition of functions problem where we had to find f(x) and g(x)=4 ... I put: 1/2x-2
I think the b^2 - 4ac with 4 graphs was the upside down parabola which had its y intercept below the origin
- There was one that we had to see which function had a different period; that was whichever answer did not have a 2 in front of the x.</p>
<p>^^ yes I had that, so...
- f(x) - g(1) is negative when f(1)<g(1)</p>
