<p>what was the fahrenheit one???</p>

<p>and what was the x^2 and 2^x roman numeral one???</p>

<p>I put I, II, III for x^2 and 2^x
I put -24 or something around there. I guessed and checked.</p>

<p>(1.8C+32)=.5C, solve for C</p>

<p>oh god i think i got 4-5 wrong so far with 1 omitted. 800 if im lucky :(</p>

<p>stripedpanda, if you get 4 wrong, 1 omitted, it’s the borderline 800, 5 wrong and 1 omitted is out… sorry.
GUYS what was the “percent markup” question, NOT the video store that was n = x/0.6d.</p>

<p>^ i thought you could miss 6 and get an 800?</p>

<p>i think i put 45%</p>

<p>@stripedpanda generally, the trend is score=800-10(44-rawscore)</p>

<p>so your raw score would be (if you got 5 wrong and ommited one) 44 right-(5wrong/4)=43 (rounded to the nearest whole #). score=800-10(44-43)=800-10=790. However if hypothetically you got 6 wrong w/o any ommitted, your raw score would’ve been a 42 and you would’ve gotten a 780. so i wish you good luck, hopefully you only got 4 wrong</p>

<p>^thanks… this is already my second time taking it too… really really need an 800…</p>

<p>Was the question asking for the temperature at which the fahrenheit represenation half of the celsius representation asking for the answer in celsius? I put -24.6 (celsius).</p>

<p>Also, for the triangle problem where you had to find sin(a), did anyone get a=120 degrees (with law of cosines) and thus sin(a) = 0.866?</p>

<p>what about the question about the pentagonal prism or something? did you guys get 7 edges?</p>

<p>omg i put 15</p>

<p>it was 15</p>

<p>5*2 for the two pentagons + 5 for the vertical edges connecting the two pentagons</p>

<p>I put 15 too is it not 15?</p>

<p>Percent markup was 69%</p>

<p>ugh i think i freaked out and did the faces instead. oh well</p>

<p>oh its 15.</p>

<p>From wiki:
In geometry, the pentagonal prism is a prism with a pentagonal base. It is a type of heptahedron with 7 faces, 15 edges, and 10 vertices.</p>

<p>pretty sure percent markup was 45%…</p>

<p>and again:
Was the question asking for the temperature at which the fahrenheit represenation half of the celsius representation asking for the answer in celsius? I put -24.6 (celsius).</p>

<p>Also, for the triangle problem where you had to find sin(a), did anyone get a=120 degrees (with law of cosines) and thus sin(a) = 0.866?</p>

<p>also, did you guys get 50% for that box plot problem?</p>

<p>i dont remember what i put for percent markup. its new-old/oldx100 though</p>
