<p>same with range i put circle and point as well btw the matix question was 5 by 4 right?</p>
<p>The circular surface one was a circle of a point because if they were 2D they could form a point or 2 spheres could form a circle.</p>
<p>The one where you have 99 pieces of data is the range. The range couldn’t decrease if you have another point. There would always be the existing minimum and maximum, it could only become larger.</p>
<p>Yes, 5x4 because
(5x2)*(2x4)->(5x4)</p>
<p>Yup I got 5 x 4</p>
<p>How generous do you think the curve will be?</p>
<p>There was one question that gave you the vertices of a triangle on a graph and asked what was the largest angle. What did you get?</p>
<p>Inverse proportion one? (150 when distance is 3, find when distance is 12)</p>
<p>I thought that was definitely harder than the two official tests, managed to answer all 50 but don’t feel very confident about 4-5. Box and whisker plot threw me off too at first.</p>
<p>I got like 120 something? Found 3 distances and plugged into Law of Cosines.</p>
<p>The inverse one I omitted, I think.</p>
<p>god i can tell already it won’t be the “hard” questions that’ll prevent me from getting an 800 it’ll be the easy ones.</p>
<p>Inverse I got 37.5 by using xy=k</p>
<p>did u guys think it was harder than some of the practices?</p>
<p>Same the box and whiskers one threw me off. What did you get?</p>
<p>I didn’t get 120 for the triangle one but then again I didn’t know how to do it lol.</p>
<p>13 or 8 for whisker nonsense?</p>
<p>What did you get for the matrices problem #50?</p>
<p>I think I got 13 for that one, was debating between 8 and 13 because I wasn’t sure which were min/max, checked afterwards though and I think 13 is right.</p>
<p>What did people get for the question involving x increasing with the function? I think I chose the answer with I and II.</p>
<p>I also got 120 for the triangle one, just did 180 - 2 inverse tan of the sides.</p>
<p>I thought it was definitely easier than Barron’s. I was freaking out because I was consistently doing badly on them.</p>
<p>I got II and III for the increasing with function. I didn’t choose the one with 1/2^x</p>
<p>How about the question asking the height of the cliff (where the angle was 30 degrees, and then 45 degrees when the person walked closer)? I got 17.32 for that.</p>
<p>Also, could someone explain the 99 data point question?</p>
<p>range can’t decrease bc range will either remain the same or increase when a new term is added</p>
<p>I think I got 41 for the height of the cliff.</p>
