<p>Principals salary problem… 94000/ 5 times 47</p>
<p>agree with NCdukie. Doesn’t really matter, doing more harm than good.</p>
<p>NCdukie, other questions? Like what? We have answered like 20% of the test already and the other 80% was just elementary math.</p>
<p>However I was also presented with a very persuasive justification of it equaling zero if each number is its own term:
(2/3)(3/4) … ([n-1]/n)(n/[n+1])</p>
<p>for 2/3*3/4 the two 3s cancel each other out and you are left with 2/4 however the next term if each thing is an individual item would be 4/5 and the fours would cancel out and you would have 2/5 and you could keep going like that to infinity and the denominators would always cancle out with the new numerators and at the “end” you would be left with a 2 on top and an infinity+1 on the bottom.
Meaning the correct answer would be 2/(infinity+1)=0</p>
<p>what was one of the last q’s that was like an integer A^X-3… </p>
<p>idr the question or what i put exactly (was rushing by then)…but what did you guys get for the answer?</p>
<p>[UPDATED x4] I’ll post here the answers everyone has listed so far in addition to some that I got:
Dice problem: 1/2
Shaded regions: 18
Multiplying fractions problem as x gets greater and greater: 0 (UNCONFIRMED: Need clarification on wording or question)
Simplifying polynomial problem: (W+X)^2-(Y+X)^2
Circle inside circle radius: 1/2x
Large rectangle: 1/2
Slope point problem (slope was like 4/5 and you had to find an equal point): (x+5, y+4)
X intercept: (9,0)
Tan of angle: >0
Geometric series (12, -4, 4/3, -4/9): 4/27
Smallest fraction problem [a is between 2 and 4, b is between 4 and 6, c is between 6 and 8, and d is between 8 and 10… you have to find the smallest number possible given (a/b)(c/d)]: .2 (something is off with the numbers i used in this example, but the concept is right)
Distance, midpoint problem [I don’t remember the exact numbers, so I will use my own in order to show the correct method: endpoint was (2,6), midpoint was (-1, −3)]: the x value of the other endpoint was −4
Principal’s salary: (94000) / (5(47)) or salary / (days worked per week * number of weeks)</p>
<p>Guys, what do you think a -3 would be? So far I’m down one (put 1/2 for the fraction problem), but might have missed another 2 to silly mistakes…</p>
<p>@chachaseeds −3 would most likely be a 33… each problem is usually equal to a point for about the first 6 problems missed in the math section.</p>
<p>I think -3 will be around 32~33.</p>
<p>I gussed 2 and there was probably like 3 silly mistakes I made.</p>
<p>So I’ll probably get something like a 30/29…</p>
<p>I am also interested in the A^X-3 < 0 problem.</p>
<p>I said that A had to be negative and X had to be even because a negative number to an odd power is negative. HOWEVER, the answer choice that said A is negative and X is < 3 works as well doesn’t it?</p>
<p>It was A is negative and X is even, correct?</p>
<p>@nbasuns2 That’s what I put, but A is negative and X is < 3 works too doesn’t it? Anyone else have any input?</p>
<p>that’s what i put, so i’m inclined to agree :D</p>
<p>can’t afford to miss anymore!</p>
<p>I also got A is negative and X < 3. I’m pretty sure that’s right.
EDIT: Actually, I think I may have put A is negative and X is even. The X < 3 was for a different problem.</p>
<p>Wcc,
It was definitely A had to be negative and x had to be an even number.</p>
<p>@Coconut, I agree that the works, but explain why A is negative and X is < 3 DOESN’T work…</p>
<p>I forgot what the X < 3 answer was for… I may or may not have put that… But was there another problem that had an answer X < 3 or something?</p>
<p>No there wasn’t. I think the X is even answer is correct even though X < 3 seems to work as well (can anyone show otherwise?) because it seems to be a BETTER answer (as A increases, it gets even more negative when as it gets less negative when X < 3 [although it will always be negative])</p>
<p>It asked for a situation in which it was always negative. X < 3 is not always negative. :o
Or maybe it was because it said a negative integer… And X < 3 would make it a decimal.</p>
<p>Yea, well then I forgot which one I put… 
So I’ll have to count that one wrong too…</p>
