PSAT 2010 Wednesday General Discussion

<p>Krazy - I’m so glad we only have to identify what’s wrong and not correct it :D</p>

<p>I changed the Egypt question at the last minute from E to A just 'cause I felt like they wouldn’t make the supposedly most difficult question (last one of the section) so simple.</p>

<p>Here are a few of the answers I put… in no particular order. Please tell me what I missed and what other people got. </p>

<p>Form W</p>

<p>=MATH=
1)Cube with volume of 10
The answer is 640 because if the side of the second cube is four times the side of the first, the ratio of volumes should be 1^3 : 4^3, or a 1:64 ratio. Since the first cube had a volume of 10, the second must be 640.</p>

<p>2)Letter Letter Number AA2
The answer is 26 x 26 x 10 or 6760 since repeated letters are allowed.</p>

<p>3) Average of 30 numbers
I forgot the exact question, but I put 9.1 I believe. You were supposed to find the sum of the two sets and then divide by 30.</p>

<p>4) Smallest to largest
rtx, rt(x+1), rt(x) + 1</p>

<p>5) rt(x + 7) - 5 = Positive integer
I put 42, but there are other possible answers.</p>

<p>6) Sports and Drama
You had to subtract the sum of everyone listed from 250 to find x. x was 20 and you had to add that to 21 so the final answer was 41.</p>

<p>7)(x-2)(x+2) Factor
I put -400. Expand (x+2)(x-2) to get x^2 - 4. Distribute with 100 to get 100x^2 - 400.</p>

<p>8) The number between .3 and .4
.35, just take the average.</p>

<p>9) The January sale
(1200 + 2^5) - (1200 + 2^1) = 30</p>

<p>10) Parking Lot
The length is 315. Add up two widths (x) and two lengths (3x) to get 8x total, or the perimeter, which is 840. (840/8) x 3 = 315.</p>

<p>11) Music store
n > 20. You had to set up 6n > 3n+60.</p>

<p>12) 50 days after Sunday
Monday (Yea, I counted on my fingers for this one just to make sure.)</p>

<p>13) Popcorn sale
Month 4. Overall sales when up while the sale of (drinks?) went down. At no other point in the graph did the sale of popcorn increase that much.</p>

<p>=READING=

  1. “Very human and very understandable”
    I interpreted this as sympathetic.</p>

<p>2) In the one about the girl trying to talk to her father, she spoke with urgency because she knew he was about to be distracted.</p>

<p>3) The girl’s father talked a lot in the country, but was reserved in the city. (His daughter wished he talked more in the city because there were people she could also talk to.)</p>

<p>4) Curtail (Guessed)</p>

<p>5) Apocryphal (Guessed)</p>

<p>6) Affronted (Guessed)</p>

<p>7) Fisherman’s response was to qualify his earlier statement, imo. I think he wanted to imply that he wanted what’s best for the girl and he assumed that she wanted to go to school and just wanted to make sure. </p>

<p>=WRITING=

  1. I put No Error for the First Lady sentence. (Guessed)</p>

<p>2) Ensured not insured (Diction error?/Guessed)</p>

<p>3) For the last question I put the example in which monkeys use tools to get the food or whatever since it was earlier claimed that they used tools and didn’t consciously think about value of these tools.</p>

<p>Is it me or was the Writing section harder than the Writing section on the October SAT (last Saturday)?</p>

<p>I just hope I get 770/800 on Math and get low 700 or higher for Reading and Writing to make the cut-off. Living in the Silicon Valley in California doesn’t really help though. :P</p>

<p>I agrees with all … i remember haveing 315, but i just don’t remember what eh question was? what rectangle question?
was it like 105 *3
what was the 42 problem? i def got 42</p>

<p>I said that the part of Egyptian one that was wrong was the “build or build” part…Is that right?</p>

<p>Awwww nooooo I forgot to subtract 2^1 from the 2^5 nooo</p>

<p>I also agree with all of your answers, TwoThirtyNine. :smiley: <em>phew</em></p>

<p>Should’ve been “assured,” but that’s the right error nonetheless.</p>

<p>Japanese Cartoons: I also said “better known” since it was only comparing two things, but was REALLLY unsure. Will somebody expound, please? :3</p>

<p>I’ll second impair/minimize. Hypertension is high blood pressure, which would mean the conrtrol was somehow faulty. Plus, you can’t “aggravate” control of blood pressure.</p>

<p>I also had Month 4.</p>

<p>“I chose minimized though, not aggravated/buttressed. Also, the month question was definitely 4. It referred to the “change from the previous month”.”</p>

<p>The greatest change occurred in Month 3. The amount of containers+drinks sold went up while the amount of drinks (bottom line) went down. Therefore, it meant more containers were sold during Month 3 than any other month. And the increase of containers sold from Month 2 to Month 3 was by far the greatest.</p>

<p>I got the buttressed one wrong, but I guessed the month one right :B</p>

<p>What was 640 the answer to?</p>

<p>Are you sure on this? I put no error cause best sounded like it would fit…</p>

<p>@ 1x612nt13 : I had EXACTLY the same answers as you :)</p>

<p>Why is increased/diminished wrong for the blood pressure one, increased blood pressure = hypertension and diminishing the correlation would mean that it no longer is proven correct.</p>

<p>The “42” problem: you could either graph the function, sqrt(x + 7) - 5, or just set it equal to one or two and solve. You will get 29 or 42 or 57. It has to be less than 60.</p>

<p>Yes, 640 was the answer to the cube question.</p>

<p>If it was comparing two things, then it is “better”.</p>

<p>@ AaronBurr: you had to calculated out the # of popcorn sold each month from the lines… as there was a drop in soda sold, the # of popcorn sold was actually MUCH higher becuase their total didnt change much</p>

<p>MaSaysImSpecial - the sentence referred to blood pressure regulation, not blood pressure. I don’t think increased regulation causes hypertension, although I got the same answer as you.</p>

<p>"Why is increased/diminished wrong for the blood pressure one, increased blood pressure = hypertension "</p>

<p>Aha!
But it wasn’t blood pressure. It was BLOOD PRESSURE REGULATION. :slight_smile: Increasing regulation would maintain homeostatic control, if such a thing is even possible.</p>

<p>For the month problem, yes the greatest change occured in month three, but I think the question asked which month showed the greatest improvement over the last, which is month 4.</p>

<p>…I hate life. LoL.</p>
