<p>Thought it was relatively easy compared to the practice tests I took but I was more prepared this morning then I was when I took any practice tests. </p>
<p>In a (x,y,z) coordinate system, what does the equation x=1 represent?</p>
<p>a. a plane
b. i forget
c. a line
d. a point
e. a half space</p>
<p>i put a line is that right?</p>
<p>Don't discuss questions, but I think that would be a plane.</p>
<p>Well not discussing questions, how about general feel of the exam. Personally, i was pretty happy with it. :)</p>
<p>I found it easier than the practice exams actually. I thought I might have accidentally take the math 1 test by mistake.</p>
<p>did you get no possibilities for the one with the triangle and 42 degrees, yes, it is a plane, and lol, the first time I flipped to the math 1 exam and almost took that one. Did you get 150 degrees as the one that couldn't be for the theta and alpha question where both sin theta=.5 and cos alpha=.5</p>
<p>yes hyperfreak i got those 2 answers. This means i can only get 4 wrong now to get an 800 :-/. Still pretty confident however.</p>
<p>I think x=1 is a LINE........in the x,y co-ordinate system is is DEFINETLY a line.......so its remains the same in a 3-d environment too.....if an equattion can be represented in the y=mx+c format then it is a line......</p>
<p>no, you're only thinking in 2 dimensions. In 3 dimensions, you can still extend into the y and z dimensions. Just try to visualize it and you'll get it, its definitely a plane</p>
<p>No possiblities for the triangle one and 150 for that other one. So far so good! How many can we get wrong and still get an 800. The only one I know for sure I might have gotten wrong is that one about standard deviation. I had no idea how to do it.</p>
<p>ya...x,y,z is 3d, so it's a plane.</p>
<p>Missed the triangle. </p>
<p>Overall, easier than I expected.</p>
<p>i feel good about this test, i didn't skip one question, now, i'm gonna keep on surfing the web and check this forum like every 5 minutes, much easier than i expected, and had no time problems</p>
<p>O I didn't mean to post stuff about specific questions, could someone please delete my posts!</p>
<p>that Q is a plane, I didn't have enought time to prep for this test so I think I did worse than I could have. I was also kinda pressed for time. I picked 150 for that cos+sin problem, and I picked 1 possiblity for that triangle cuz I was rushing haha.</p>
<p>^^^^ exactly what i put. super yes, since i didn't study at all and am freaked that i will get a lower score this time lol.</p>
<p>what about that f(x-1) question? i was confused...I knew it was f(4.7-1) but what was that?</p>
<p>yea that Q was mad weird, I think i put 3.7 and meant to come back to it but never did</p>
<p>It's 3.7.</p>
<p>Thank god for Barron's. Finished the test in 30 minutes, omitted 3 or 4.</p>
<p>I agree....that was the most random yet easy question.</p>
<p>How many do you think you can get wrong/omit to still get an 800? I left 3 blank and was unsure of a couple, so I'm banking on a good curve to get a good score.</p>
<p>Haha lol the answer to that question was 0.7(the f(x-1) one that is). PM me if you want more details as to why I got that answer!!!:)</p>
<p>It's a massive curve, like 88%tile+ get 800, I also left a few blank and was unsure on a few and I figure I'll get in the high 700's</p>
