March 2012 SAT I Math Thread

<p>whats the answer for the average mean of the bar graph one? 3.2 or 4?</p>

<p>pretty sure it was 3.2</p>

<p>Yes ^^. 3.2</p>

<p>3.2. I feel looking at it visually you could conclude it was not 4.</p>

<p>how did you all get 34 for the triangle perimeter question? the length of the triangles were 5. 6. 6 (5 being the inner part), and the question asked for the perimeter of the outside, which was 6*6=36?</p>

<p>Wait, which one was the one about the octagon in a square? I don’t remember seeing that one and I had the experimental as well.</p>

<p>all the outside triangles were equliateral. the bottom side length of the isosceles triangle was 5 making the bottom equilateral triangle a 5x5x5</p>

<p>Then I think that was my experimental math section.</p>

<p>I didn’t have the octagon in the square either… are you sure you didn’t get the experimental?</p>

<p>@perfect 36</p>

<p>It was 34. Not 36. </p>

<p>Another SAT dirty question has trumped another innocent soul.</p>

<p>@jimmypod</p>

<p>can you explain though? im not sure why. this really sucks though, i think this was the only question i missed on the entire test</p>

<p>@stressedout.</p>

<p>Yes. It is experimental. That’s 3+ people that don’t’ recognized it already.</p>

<p>@Jimmypod yes i got 34 also.</p>

<p>@perfect36
You had to take into account the 5 instead of using 6 on all the sides.
So 4 sides of 6 is 24 + two sides of 10 = 34.</p>

<p>Thats how i did it at least.</p>

<p>@perfect36</p>

<p>The triangle that was inside (dotted lines) was a 6, 6, 5 triangle (the perimeter = 17. You probably thought it was a 6, 6, 6 triangle)</p>

<p>Thus, the outside perimeter would equal 2(6) + 2(6) + 2(5) = 34</p>

<p>Was the Octagon a fill in or multiple choice? and was it near the end or the beginning?</p>

<p>All i remember was some sort of 6 sided figure inscribed into a circle, and asked for the angle (which was 600.</p>

<p>OK, your big shape is NOT a triangle, so every side must be counted carefully.
You have 2 6,6,6 triangles and 1 5,5,5 triangle. The inner sides are dashed and don’t count. 6 + 6 + 6 + 6 + 5 + 5 = 34</p>

<p>You are guys are awesome! You make me realize that in the large scheme of things, a discouraging and grueling exam like the SAT doesn’t matter at all, and that we’re a family.</p>

<p>It was fill in question and at the end.</p>

<p>It is definitely experimental.
Since I have 2 fill in math section, and no one recognized this question.</p>

<p>oh, wow ok, thanks for explaing. appreciate it</p>
