Wednesday 2012 PSAT General Discussion

<p>Can someone refresh me with the grid in that has an answer of 8?</p>

<p>I got 600! I wasn’t sure about that one at the time so I’m glad to see that someone else got that. </p>

<p>Studious Maximus- can you refresh me on what the angle question was that had an answer of 100? Was that the one with 2 isosceles triangles? I could have sworn that it was 70 degrees as the answer, but perhaps I’m wrong about that. And do you remember a question with the answer 130? I’m kind of worried that I made a silly mistake on math because I feel like the curve is going to be really harsh…</p>

<p>The triangle of 40, 70, 70… That was the one that had an answer of 100. Haha sorry if that didnt help</p>

<p>Can someone refresh me with 1080?</p>

<p>I don’t understand… I got 70 as well. If the ∆ was 40, 70, and 70, and the question asked what x was (an angle) then x=70</p>

<p>And what about the Roman numeral question II & III? I forgot. Please someone answer me :(</p>

<p>@Smarty.
3 doors for first choice, 2 door for second choice.
X X

X X

Dog has two choices then 3 choices on the way there.
Way back looks like
X X
X
So way back has two choices and one choice.
Total choices is 2 x 3 x 2 x 1 in that order. Which equals twelve.</p>

<p>For the sock question.
There were red blue and white (colors might be wrong)</p>

<p>What is the MINIMUM number of socks you need to get to have a 100% Chance of having two of the same socks.</p>

<ol>
<li>Pull red</li>
<li>pull blue</li>
<li>pull white
therefor, it is possible to have 3 trials and not get 2 of the same sock.
But you have already pulled one of every sock, so the next sock is guaranteed to be the second of one color. So, the 4th sock is the answer.</li>
</ol>

<p>Man! The sock question was easy.
But I still don’t understand the dog question xD</p>

<p>Nvm. I understand the dog question now. But didnt it ask like how many ways can the dog go without going through it twice? Something like that. Not how many choices did the dog have?</p>

<p>The 100 degrees problem was indeed the question with the two isosceles triangles. It worked out that one of the base angles was 40 degrees, so the other base angle was 40 degrees as well (a property of isosceles triangles). This left 180 - (40 + 40) = 100 degrees for the vertex angle. I’m actually surprised so many people missed this one.</p>

<p>How many the dog can go through without going threw twice is what I showed you. He has 3 x 2 x 2 x 3 or 36 total total ways of going through the doors, but only 12 without going through the doors twice. I just showed you how I eliminated the problem of the dog going through doors twice in my explanation. Sorry if it wasn’t/ still isn’t clear enough.</p>

<p>For the 10% book question I think I put 3000000? I forgot how many zeros tho lol.</p>

<p>Ok, I was confused and thought the two base angles were 55 degrees, not 40. I’m really hoping I got this right and just somehow am remembering it wrong…</p>

<p>I can use factorial for the dog question!!! Man but I used it wrong. </p>

<p>2! * 3! = 12… UGGGHH</p>

<p>for the waters question, it was talking about the fog so would the answer be covered?</p>

<p>what is the answer to the other CR question; shackles or the riding tiger?</p>

<p>and what is the answer to the 8th (last) vocab fill-in-the-blank question on section 1? i put c.</p>

<p>@Aria</p>

<p>The answer is “moistened”
It referred to it in a context where the fog was juxtaposed against the lifeless, dry valley, so it mean it in a way that explained how the plants were able to grow due to water from the fog.</p>

<p>The answer to that CR question was shackles.</p>

<p>Ahh. I read the sock questions wrong and put 7. I thought it was saying the minimum to guarantee 2 different socks.</p>

<p>And also…I was sick on my PSAT test day so I was offered a choice. I took the PSATs on wednesday but I wasn’t feeling well. I can cancel my PSAT score within the next week or so, and substitute a SAT score taken between Nov 2012 and March 2013 for the National Merit. (They would take off the last 0 for the SAT score and calculate the SAT writing score without the essay component)</p>

<p>I think I did okay on the PSATs this year. It’s just that on the first section, (Reading) I ran out of time and had 6 questions left with 2 minutes to do them. So I rushed and did them, but I’m not sure if they’re right. And reading is my second best section so I need a high score in it.</p>

<p>My worst section is usually writing. I felt like I did pretty well, but I always feel like a did well and when I get the test back, I always made a couple of stupid mistakes. </p>

<p>So should I keep my PSAT score or substitute a SAT score? I’ve never taken the SATs before. In 10th grade, I got a 221 on the PSATs. Cutoff score here for semifinalist in my state is usually 219, 220 , or 221 btw.</p>

<p>So I have been seeing a lot of discussion on the shackles CR question but don’t remember it making much of an impression on me as difficult. Would someone mind describing that question?</p>

<p>This thread has most of the math and critical reading questions answered. See how many you miss and look at some old curves and see how you would have done.</p>

<p>Also, it depends on how the SAT score substitution works. Can you substitute it with ANY score between nov and march? Or can you substitute it with the first SAT you take? Because if you can use any test then you could just take it 3 or 4 times and have that many more tries to hit the cutoff.</p>
