<p>[absolute value graph y= |h(k)|]
ANSWER: D, all points are above the x-axis</p>

<p>OK, for the 2x = y and the 2y= w question, the answer was 36 = x. If i recall correctly, the expression was similar to 4x + y + z = 360, and it was multiple choice.</p>

<p>what would a -3 overall look like, score wise?</p>

<p>Are all 3 questions Multiple Choice?</p>

<p>do you mean 51 raw score or 3 wrong answers which would yield 50 raw score.
From a table which has been referred to on this thread a 51 is on average 740 and 50 on average 720 +/- 20</p>

<p>Hey luceverita. What do you think a 53 raw will yield?</p>

<p>@DoctorTye
Yes, the answer is 36 confirmed.</p>

<p>luce: nop, -3 overall…1 blank, 2 MC wrong…so -3. i have no clue…ppl say the M was hard while others say easy…im hoping the majority thought it was hard</p>

<p>EDIT: yep, i choked on Math, choked like the San Jose Sharks in the playoffs every year…</p>

<p>I think I omitted one, got one grid-in wrong (the bakery one, ugh!), and got one multiple choice wrong (quickly choosing 1/2r^2 thinking it was (1/2r)^2). I guess that’s a 51/54, no? I hope I end up in the low-to-mid 700’s.</p>

<p>Oh, for the question where the answer = 2, the question was 16 triangle k = 8 or something like that. It proceeded to say that the triangle (or whatever geometrical shape) was an operation (either addition, subtraction, division, or multiplication). Finally, it declared that k was not 8 and that it had to be an integer. Using all this info, one can determine that the operation was division and that k =2. Someone add it to the consolidated. :P</p>

<p>i wonder how so many of us, including me, managed to get the bakery one wrong…</p>

<p>@xavier110
The bakery was a grid-in? Hmm… I got that wrong too :confused: Oh well, at least, it’s not -1 score.</p>

<p>I thought the bakery was just a simple question so I did 4x3 = 12.
But I chose 4 in the first place blah</p>

<p>doctor: 53 math is on average 790 +/-10 so you could still score 800.</p>

<p>@DoctorTye
Yup, confirmed that the answer for that was 2.</p>

<p>That gives me hope. Woohoo. Lol. I’m going to try to remember some more of the questions to help the consolidated.</p>

<p>viggy, I think the M was hard. with -3 you could still score 750</p>

<p>“[2 times c is 5 less than b and product of b and c = 45]
ANSWER: 2c-5 = b and bc= 45”</p>

<p>I believe it’s 2c = b - 5, bc = 45.</p>

<p>Which question corresponds with the 72 answer for the grid-in? I recall 72 but i would like to be sure.</p>
