Act math section february 2012

<p>Guys, he’s a ■■■■■. Stop responding.</p>

<p>@needhelpnow, they aren’t idiots, and neither are you. I am just pretty sure that since you were probably booming through the questions because u seem to be very proficient at math, you may not have seen the exact wording of the question. if the question was worded exactly how the previous poster said, then yes, 0 is correct, but I am almost certain that it was not worded this way. I am sorry that I cannot provide any further information.</p>

<p>@ugotsever834, if you don’t care to help the people on here, please leave. The point of this is to help each other out and to explain problems that people don’t understand. If you want to help everyone out by posting what <em>you</em> think that the question said, it would be much appreciated. Until then, please ■■■■■ somewhere else.</p>

<p>I am also not a ■■■■■. Idk why you would think that…I’m trying to the best of my knowledge to help out this forum, but unfortunately all I can say is that I am fairly certain that the question was not worded in the way that was posted on here.</p>

<p>Not gonna lie im still with ugot…the wording was different.</p>

<p>@ugotserved834 Okay, then call up your genius friends and ask them what it was… Trust me, we are all eager to hear your explanation.</p>

<p>It think I know what you did wrong. The question asked for a sequence, not just 2 number multiplied. It is a string of number multiplied together. I also made the same mistake so the answer is 0.</p>

<p>I also got 1 because I thought it was asking about each pair of terms so like…</p>

<p>2/3 * 3/4 = .5</p>

<p>3/4 * 4/5 = .6</p>

<p>…</p>

<p>99/100 * 100/101 = .98</p>

<p>therefore getting closer to 1,
i could have misread though…</p>

<p>TO ALL THE PEOPLE WHO SAY THAT THE WORDING WAS DIFFERENT ON THE FRACTION PROBLEM,</p>

<p>Please tell us what the wording was… Do not just say that the wording on here is wrong. I have listed the question below here AGAIN as a point of reference. Please tell me what is wrong with it.</p>

<p>(2/3)<em>(3/4) … ([n-1]/n)</em>(n/[n+1])
It asked what the product was as n approached infinity if n is greater than or equal to 3.</p>

<p>Actually there are more problems with this fraction problem that most people are recognizing, namely the value of n. Hopefully the problem gets thrown out because the first two terms in the sequence are 100% incorrect. If n= the term in the series (i.e. n=10 for the 10th term) and we are starting with the 3rd term then n should not be the same for the 3rd and the 4th term…
2/3<em>3/4 makes the statement that either 3 is always equal to n, which means that last term is still 2/3</em>3/4 or the first two terms they give are an exception for which n does not increase…</p>

<p>Okay, FOR THE FRACTION PROBLEM, it appears that the difference in the two answers is that one group of people (the ones who think that it is 1) think that it was asking for the product of only the last 2 terms. The ones who say it is 0 think that it was asking for the product of ALL of the fractions.</p>

<p>I am 99% sure that it did NOT only ask for the product of the last 2 terms. That would be the only way that the answer could equal one.</p>

<p>Thoughts?</p>

<p>^ayep agreed</p>

<p>Also, WHEN YOU ARE REPLYING TO SOMEONE, <em>please</em> post @TheirUsername at the beginning of the post so that it is clear who you are talking to. This is especially important when many people are posting at once like on this thread.</p>

<p>so…write to the ACT? lol. Again, I am sorry for not being more helpful, I just looked at my calculator history and I did not multiply each term together ( I did at first, then went back after I finished). This leads me to believe that there was something in the wording that I didn’t catch.</p>

<p>@wccirl- its not as easy as just multiplying the last 2 terms, you also have to know how to take the limit. There probably is a non-calculus way to do this, but I guess I over-thought it and did it that way.</p>

<p>@ugotserved834 can you call your friends who said it was 1 and ask them what it said? I’m 99% sure that what is posted on here is correct, but I could be wrong. I did remember thinking how poorly worded it was when I read it.</p>

<p>Also, what did <em>you</em> put? 1?</p>

<p>Wait, I think the answer might be 1, let me explain.
If we imagine that a “term” in the series is two numbers multiplied: that means that 2/3*3/4 is ONE term in the series, then the answer is undoubtedly one. Either way this question is nonsense and shenanigans…</p>

<p>@ wccirl I did put one. I did call my friend, but he is forgetful and wasn’t sure about the problem, all that he said was that he was fairly sure it was one, and he checked with about 3 other people in calculus who said it was one as well.</p>

<p>hey let’s stop arguing about this mindlessly and focus on other questions. </p>

<p>Let’s just say it’s 0 until someone who thinks it is 1 can remember the exact wording. I suppose we’ll find out in 3 weeks anyways lol</p>

<p>rdash may be on to something.</p>
