<p>So.. trapezoids? (31.5, anyone?)</p>
<p>yeah got 31.5
what did you get for the 4,5,6,7,8 even number thingy and the vowels</p>
<p>totallyg uessed… i don’t remember… i think i got like the one where there was a 44 somewhere… like 3x4xx (the digits)</p>
<p>hmm idk, it wasn’t that bad though. For the one that was like 4x^4 + 3x^3, etc. and 2x^2 + 10x + 5, they asked what was the addition of the point that is above the parabola and below the other crazy parabola. I got 10 :s</p>
<p>same! i had no clue tho to be honest… i just knew x = 5 could be it, not sure about the y.</p>
<p>oh coool, lol I guess we’re the only two people who did math level 1 <_<</p>
<p>heh yeah math level 1 for the win !</p>
<p>honestly i was more focused on my chem one today… i might end up retaking math level 1 if i get anythin less than 720</p>
<p>I got 3380 for the vowels and 3/5 for the 4,5,6,7,8 thing.
What did you get for the matrix thing? I couldn’t decide if it was horizontal or vertical!</p>
<p>Also, the x+y thing was 11. (5,6) was the point.</p>
<p>dang, how did you find that point? I wasn’t even sure how to graph it properly.</p>
<p>I did Chem and Math, didn’t study at all for Math though. For the parking lot one where its 4$ for the first hour and then $1.50 for every half-hour or part thereof, I got $18.55. What’d you guys put?</p>
<p>I got $18.55 for the parking lot one. I got the graphing one using a graphing calculator.</p>
<p>For the parking lot one, wasn’t it 2:45 to 11:00 AM?
Therefore its 2:45 - 3:45 = 4$ (1 full hour)
3:45 - 4:00 = 1.50 (1 partial hour)
4:00-5:00 = 3.00 (2 half hours)
5:00-11:00 =18.00 (12 half hours)</p>
<p>Total: 26.50</p>
<p>For the trapezoid, got 27. Used system of equations.</p>
<p>Whats the SAT I curve usually? Been searching around but i’m not sure if my data is accurate.</p>
<p>The curve is pretty harsh…
typically-
50 = 800
49 = 790
48 = 780
47=780
46=770
45=750
etc…</p>
<p>For the deduction of .25 points for every wrong answer, if you have 44.5, do they round up to 45 or down to 44?</p>
<p>round up. can you find a reference / source for the curve?</p>
<p>For the parking lot one, it said there was a 30% discount.
Therefore, it was $18.55.</p>
<p>The source for the curve can be found in the official CollegeBoard Guide for SAT Subject Tests. It typically goes:
50: 800
49: 790/780
48: 780/760
46: 760/750
And so on.</p>
<p>Toystoryfan,</p>
<p>what did you get for the trapezoid question?</p>
<p>what was the graph to the question with “ax^4 + bx^3 + cx^2 + dx + e, where a is positive”?? was it A or B</p>
<p>what was the matrix question?</p>
<p>and was the trapezoid question 30.5 for sure?</p>
<p>To the first question, the answer was choice A because it was positive and there are three curves if the exponent is four.
The trapezoid question was answered in the first post of the discussion. I’m pretty sure the other user who used the system of equations isn’t right. So yeah, 31.5.
Also, the matrices question was answer choice E, I believe. I multiplied everything out, and it got me that weird number like 765, which was the same number if you multiplied out the matrices in the question.</p>
