<p>When I attacked this problem today, the first thing I realized was that |f(x)| had to be positive. The absolute value of anything is positive (well, unless you are taking the absolute value of 0 and don’t consider 0 to be a positive number). </p>
<p>Now, you are looking for a f(x) that is less than the absolute value of f(x). Realize that f(x) is just a fancy way of saying y - as in the y-value or y-coordinate.</p>
<p>Armed with those two pieces of knowledge, you should realize that the problem is asking you for a point x at which the y value of negative. </p>
<p>We can therefore eliminate choices A, B, C, and E, because the y-values at -3, -2, -1, and 5 are all positive or zero. </p>
<p>Haha I will. Also that’s what I exactly did on the diagram. But mine turned out more oval-er? Also I knew that “1” is right because it could be a HUGE circle. So you could eliminate B and D. Next I drew a circle and it touched 4 points. So I crossed out C. That’s how I got E.</p>
<p>For the first time in my life I have gotten 0 wrong in a math section. The section I did was from the May 2011 SAT test. I am SOOO very HAPPY :)</p>
<p>I have a couple of math questions from a SAT test.</p>
<ol>
<li><p>Michael ran 5.5 miles each day for the first 5 of 6 days. How many miles must he run on the sixth day so that his average (arithmetic mean) for the 6 days will be 6.0 miles per day?</p></li>
<li><p>In Lewiston, 4 out of every 7 registered voters voted in the last election. If a total of 2000 votes were cast, what was the number of registered voters in Lewiston at the time of the election?</p></li>
</ol>
<p>I have seen both types of these types of questions before, especially number 2, but I can’t remember how to do them. If anyone could help, I would really appreciate it.</p>
<p>In order to be SURE that at least 3 of the scarves you’ve selected are of the same color, you need to consider the most unlucky situation. That is, if you’ve selected 6 scarves, they are all of different colors. So now you need to select more, and only when you select 9 boxes, you can be sure that at least 3 are of the same color.</p>
<p>It’s true. Sickness hinders our logic and thinking. So it’s better to take a break than to diligently study like you. But don’t feel disappointed. You did well despite the existence of the evil cold BTW, I thought you’d never get “cold” because you’re…Ice. Qube. :P</p>
<p>I took a full test yesterday and another today. Both scored about 2200+ (assume a 8 essay. I’m not very confident about my essays and to prevent a big disappointment I just take all my essays as 8.) Today I missed only 1 in Math. Only 1! My best math score ever! (Don’t laugh at me). For Writing, I got 3 wrong, two of them are idioms, and one is a stupid mistake. I think my biggest problem in grammar is that I often confuse two similar idioms, such as “differ with” and “differ to.” So I need to practice more and be sure that I understand all the usages of the idioms I’ve learned. CR is average, with 3 passage questions wrong. But it’s not that I didn’t understand the passages but that I didn’t understand certain words in the answer choices or certain sentences. So, vocab is important. Need to read more and expand my vocab.</p>
<p>Amazingly, I always get, or more accurately, “guess” right in SC questions. I used to think that SC would be the most difficult area for me because I hardly memorized vocab lists. But it proves that Direct Hits is sufficient enough, although it contains only 400+ words. From my experience, SC questions require logical thinking just as much as it requires vocab understanding. Sometimes there are difficult, unknown words in SC, but by reading critically and analyzing the sentence, you can find the simpler words that fit perfectly into the sentence.(Those are often correct answers.) Sometimes, for sentences with two blanks, you may only detect 1 blank and not know the second word. But by eliminating other choices and by analyzing the unknown word’s suffix, prefix or just think “what word does it look similar to?” you can guess the right choice.</p>
<p>However, I still think that I should review my vocab by using Quizlet. And today I’ll research some essay examples and polish my math skills which is perhaps the weakest area at the moment.</p>
<p>Finally, much to my dismay, I’ll probably quit updating for the next few days. I have two lengthy literary analysis essays and one voluminous history book to read due next week. Time is running out for me. But I’m sure you guys will get what you’ve worked so hard for! </p>
<p>Cheers to all of you who are aiming high! Never give up and don’t feel discouraged! Even practicing at the last minute is helping and improving. Good luck on 28th :D</p>
<p>Here are some questions I missed or were somewhat unsure on my May 2007 test so have a go at them if you wish. Explanations would be helpful… I’ll post answers after.</p>
<p>21.) Ms. Kovak proudly displayed (her research group’s) (most ingenious invention), a vacuum cleaner (that empties its own) dust bag (when pressing a button).</p>
<p>7.) (Because their flight was missed, the bride’s parents ran) frantically to another part of the airport to catch another plane.</p>
<p>A) same
B) Because the bride’s parents missed their flight, they had to run</p>
<p>7.) Point A is a vertex of an 8 sided polygon. The polygon has 8 sides of equal length and 8 angles of equal measure. When all possible diagonals are drawn from point A in the polygon, how many triangles are formed?</p>
<p>A) 4
B) 5
C) 6
D) 7
E) 8</p>
<p>16.) A cube with volume 8 cubic centimeters is inscribed in a sphere so that each vertex of the cube touches the sphere. What is the length of the diameter, in centimeters, of the sphere?</p>
<p>A) 2
B) root 6
C) 2.5
D) 2 x root 3
E) 4</p>
<p>Typing questions is too much work lol… I’ll do pics in the future (maybe).</p>
<p>Correction: Ms. Kovak proudly displayed her research group’s most ingenious invention, a vacuum cleaner that empties its own dust bag when a button is pressed.</p>
<p>7.) The answer is B - A makes little sense.</p>
<p>7.) C - 6. Count it. There are five diagonals which make six triangles.</p>
<p>16.) Each side of the cube will be 2 cm. Find the 3-D area of a line that goes 2x2x2…ummm so basically it’s sqrt(2^2 + 2^2 + 2^2) you just apply pythagorean but with a+b+c… and it comes out ot sqrt(12) which is 2*sqrt(3). Therefore the answer is D, 2 * sqrt(3).</p>
<p>Basically two questions. On the first one how did you know that QS was 1/2 PT? I understand the ratio of the sides is that way but what rule are you applying really here? And then on the triangle inequality question…how did you know to set up the equation like that. I knew that the side couldn’t be bigger than 12, the sum of the other sides because of the triangle inequality principle, but I don’t understand how you got the lower limit it could be or how you really set up the inequality. Thanks!</p>
BTW, I thought you’d never get “cold” because you’re…Ice. Qube. :P</p>
