<p>i’m positive it was tan-1(3/25), not 25/3. tan =opp/adj, and i’m positive 3 was opposite</p>
<p>I got 85. How did you get 90?</p>
<p>the highest possible median was 90. consider the highest possible values for each bar. i forget exactly how many were in each, but the first bar was, say, 60 - 70. the highest value there can be 70. if the bar went up to three on the y axis, there can be 3 70’s. using this method, THE MEDIAN MUST BE somewhere in the 80-90 bar. the highest there is 90… so yeah, its 90. i just learned about this in my stats class.</p>
<p>
</p>
<p>Buts its the inverse of tan not tan which is adj/opp</p>
<p>Well, let’s say it said 3 points were in the 70-80 range. I then put down all three data points as 80, because it said assuming that everyone got the highest or something like that. I did that for all categories. Then I just did the thing where you cross off each number, and 90 was left in the middle.</p>
<p>fisawalab… i also got 3/25 for the tangent. and yeah, 3 was the opposite, i checked like 5 times.</p>
<p>I took the highest also but still got 85.</p>
<p>There was something similar to this problem on the MAY sat with the median, so I knew exactly how to it, the answer was 90</p>
<p>tan^-1(x)≠[tan(x)]^-1</p>
<p>@wanton, I plotted out the points and there were an odd number which means you have to take the middle of two numbers. The problem even had a note that said if there is an odd number of digits, add the two in the middle and divide.</p>
<p>I put 85 too, anonymous, but we may have gotten it wrong.</p>
<p>
</p>
<p>Pretty sure is does equal that.</p>
<p>because cos^2(x)=[cosx]^2</p>
<p>Mark, if you’re talking about the last question, it’s 90. It asked for the HIGHEST possible median value, not the median median value, which was 85.</p>
<p>I thought that all the tests were the same…
I didn’t have any of these questions. And I asked a kid at my location about a couple and he said didn’t have any of the ones I asked about…
wt…f</p>
<p>1000000% sure on the median one-90</p>
<p>Oh, anyone know what the answer to the garden/fence question was?</p>
<p>garden was 6 by 24</p>
<p>I don’t know if ACT makes experimental questions, but I believe number 43 was made badly.</p>
<p>It was (x^2+x-2)/(x^2-1) and said which one CANNOT be the x value.
If you factor out (x-1) from top and bottom, all of the answers can indeed be a valid x coordinate.</p>
<p>Any thoughts?</p>
<p>I put 1 as a guess.</p>
<p>Umm proportional 3/2? </p>
<p>8 for the 135th number</p>
<p>what bout the perimeter one with x+5 x-3 did u guys 4x+4</p>
<p>spools, meeps, and something. I laughed at this one but I think i figured it out after a minute of getting confused by the wording. (i think it was all whatever the last line said are whatever the first one was, LOL if that makes any sense)</p>
<p>And the one with x+y=54 and x/y=7/11, the two numbers were 21 and 33.</p>
