PSAT 2011 Wednesday General Discussion

Test Preparation SAT Preparation

<p>What was the Julius Caesar one? I thought it would be “but was named” because of parallel structure. Although many people in my class put just “but.”</p>

<p>What did you put for the isoceles triangle with the equilateral? I put 15.</p>

<p>Also, what was the answer for the cylinder one? I think it had a fraction in the answer.</p>

<p>The last sentence error I’m almost postive was “no error” because if you did the practice PSAT, I know redundent lol, there was a question almost identical. I’ll post it when I get home.</p>

<p>Also what was the one with the arthmetic mean? I got 65.</p>

<p>Because B was 20 and the average was 30. So (2A+2C+B)/5 = 30 → 150
therefore 2A+2C+20 = 150
2A+2C=130
A+C=65</p>

<p>There are a few others and I apologize for the extremely long post.</p>

122

<p>Would like more clarification on: Parallelogram (how is it 20*68?), what could be added to the second paragraph, extraterrestrial tone question, the question about the thieves (I think the sentence was something like “That the group of thieves could not sell all of their stolen artwork indicated that the black market was declining.” I thought the error was in “was declining”, not “that” - shouldn’t it be “had declined”?).</p>

<p>Julies Caesar was “but”, I got a fraction for the cylinder one but don’t remember the question, average I got the same thing.</p>

123

<p>Are we allowed to discuss these answers? I’m curious if anyone from CC has ever gotten in trouble for talking about the test before they were allowed to…</p>

124

<p>Pretty sure the artwork one was no error.</p>

125

<p>Arithmetic mean(the last grid-in) question was most definitely 35. I’m 100% sure.</p>

126

<p>Aj39vn23cf2: </p>

<p>formula for area= base x height. The height (or altitude) is the perpendicular distance from the base to the opposite side.
So you know one of the angles is 150 degrees. You can deduce that the other 2 angles are each 30 degrees. 30-60-90 triangles have a hypotenuse 2 times the length of one leg (the one opposite the 30 deg angle)</p>

<p>You get the height as 20 (because the hypotenuse is given as 40). base as 68. 20*68=1360
ahh I hope that clarified for you :)</p>

127

<p>The isoceles triangle one?</p>

128

<p>Ok. What number was the arthmetic mean though? Was it 38? I need to make sure I changed my answer on the right one lol</p>

129

<p>I tried that, but if it was a 30-60-90 the altitude would have been x*(sq(3)), right? Because the bottom left angle was 60, the bottom right angle was 90 when you dropped the altitude down, and that meant the top angle had to be 30.</p>

<p>I can remember most of the problems…just not the numbers.</p>

130

<p>I think you may have made a math error-the bottom left angle was 30.
(150x2= 300; 360-300= 60; 60/2= 30, so 30 for each of the other 2 angles)</p>

131

<p>Jeffery, you are correct; 35 is the answer. 65 is wrong because in the calculation, ooo000ooo used 30 as the mean when the question said it was the median.</p>

<p>For the last question in section 1, how would you describe her actions, malevolent but forgivable, or my answer, unfortunate but understandable?</p>

<p>And in line 8, odd meant what? eccentric? I chose that over dissimilar. Not enough information in the sentence to tell.</p>

<p>And in line 11, serious meant what? considerable? I chose that over overwhelming or pensive, but now think it’s probably pensive.</p>

132

<p>AH! Crap. Forgot to divide by 2. That’s one math question wrong. What were the no errors?</p>

<p>Odd meant infrequent. “, and the odd painting.”</p>

<p>Serious meant considerable. “Since they had so little to go on, her biographers had to do some serious literary sleuthing.”</p>

<p>I said unfortunate but understandable.</p>

<p>The mean question was an easy one. Whatever the question says was what I did…I’m pretty sure I did the calculations correctly.</p>

133

<p>For arithmetic mean/median, i think it said the mean of 5 numbers a a b c c is 20 and the median is 30. </p>

<p>My answer was thus 35 for a + c.</p>

134

<p>Math answers i remember</p>

<p>1360 for the parallelogram
27 for the multiple choice about venn diagrams
7.2 minutes for the car
distance between the two points on the line (grid in) was .9</p>

135

<p>for the writing fixing sentences i think there were two with no error</p>

<p>one was about a guy making the yoyo
the other was the very last question about stolen artwork.</p>

136

<p>I got 28 for the venn diagrams… cuz there are 30 multiples of 3 between 10 and 100 and 2 of those (64 and 81) are perfect squares</p>

137

<p>10-100 inclusive, multiple of 3, not a perfect square. That’s: 12, 15, 18, 21, 24, 27, 30, 33, not 36, 39, 42, 45, 48, 51, 54, 57, 60, 63, 66, 69, 72, 75, 78, not 81, 84, 87, 90, 93, 96, 99.</p>

<p>Isn’t that 28?</p>

<p>The phrase was “four diary papers, a couple letters, notes to a french teacher, the odd painting.” Odd definitely means infrequent.</p>

<p>Edit: I’m pretty sure I put no error for the yoyo one.</p>

138

<p>i think for “odd” the answer was infrequent, not eccentric.</p>

139

<p>yeah I only got 2 E’s in the fixing sentences… the yoyo and something else. I remember a question where it was D because it was the incorrect participle form. does anyone remember that?</p>

140

<p>does anyone remember the questions and answers about the southwestern cities? thought those were unusually tough for a short passage</p>
