Nicely done! Congrats and good luck on your next steps on the road to grad school. Thanks for the debrief.

Just eyeballing it, we can see that the mean is the same for all of them (i.e. 5). But it looks like the numbers in opt B are the most closely packed together.

This is a good idea. I find it a lot more helpful to review a few questions in detail rather than just gloss over hundreds of questions. I look forward to participating.

I think A is the best answer. A) Unlike modern feminism, which derives much of its strength from rejection of an oppressive home, Marietta Holley in her novels Modern feminisim derives strength from rejection of an oppressive home; whereas Marietta (in her novels) made domesticity the basis of women's Lib. (B) Unlike the modern feminist who derives much of her strength from rejection of an oppressive home, Marietta Holley’ s novels Incorrectly compares the feminist to the novels © Unlike modern feminism, deriving much of its strength from rejection of an oppressive home, Marietta Holley’s novels Marietta's novels did not make domesticity the basis of women's lib. Rather it was Marietta herself who did so, through her novels. (D) Unlike those of the modern feminist who derives much of her strength from rejection of an oppressive home, novels of Marietta Holley Sentence is awkward and "Novels of Marietta Holley" is passive. (E) Unlike those of modern feminism, which derive much of their strength from rejection of an oppressive home, Marietta Holley’ s novels This says the novels of modern feminism derive their strenghth from...., whereas Marietta Holley's novels made domesticity... The novels do not have strength.

If xy = 7, what is xy(x + y)2 ? If we rewrite the question: => 7(x+y)^2 => 7(x^2 + 2xy + y^2) => 7(x^2 + y^2 + 14) (1) x^2 + y^2 = 3 Sufficient (2) x^2 = 1 => x = 1 or -1 From question: xy = 7 => y = 7 or -7 => (x^2 + y^2) = 1 + 49 Sufficient Answer is D

No problem hardikrs. It's funny how the answer remained the same.

1. The Anasazi settlements at Chaco Canyon were built on a spectacular scale with more than 75 carefully engineered structures, of up to 600 rooms each, were connected by a complex regional system of roads. A. with more than 75 carefully engineered structures, of up to 600 rooms each, were The second "were" should not be included in the sentence. If you take out the modifier, the sentence reads, "settlements...were built on a spectacular scale with more than 75 carefully engineered structures were connected by a complex regional system of roads. B. with more than 75 carefully engineered structures, of up to 600 rooms each, Correct. built on a spectacular scale with more than 75 carefully engineered structures,..., connected by a complex... C. of more than 75 carefully engineered structures of up to 600 rooms, each that had been scale of more than 75 carefully... is incorrect. Also the modifier (of up to 600 rooms each) should be set apart with commas. Comma after 'rooms' is out of place. D. of more than 75 carefully engineered structures of up to 600 rooms and with each 'of more than 75..." same problem as above. Also it's unclear whether the 75 structures have 600 rooms in total or per structure. "And" is incorrectly used. E. of more than 75 carefully engineered structures of up to 600 rooms each had been "of more than 75..." same issue as above. Also 'had been' as it's used here implies that the "spectacular scale" had been connected by a complex... rather than the structures themselves being connected by the roads.

Number of ways to choose two fruits is 3C2 = 3 Number of ways to choose two vegetables = 3C2 = 3 Probability of choosing Fruit and Salad = 1/3 Probability of choosing Squash and Peas = 1/3 Probability of choosing both sets = 1/3 * 1/3 = 1/9 Answer is B

Good approach. I got C too.

I got C by picking numbers: W/L = 8/7 Assume W = 8 and L = 7 __________________W=== L=== Total 1. Original Solution:==8===7==== 15 2. Remove x parts: =-8/7= -1=== -x 4. Add x parts of w:==x ===0 ====x 3. Net New Solution:==9===6==== 15 Step 1: Original solution is 8 parts water, 7 parts lemonade. Total is 15 Step 2a: Remove x parts of the solution Skip to step 3 (bottom): Solve for new L. New solution remains 15 parts in total. Because new solution is 40% lemonade, new L is .4 * 15 = 6. Therefore, new W = 15 - 6 = 9. Return to step 2b: L was originally 7 but is now 6. Therefore you took our 7 - 6 = 1 part of L. => W/L = 8/7. Therefore if L = 1 then W = 8/7. => x = 1 + 8/7 = 15/7 ~ 2.14 Answer is C. Does anyone have a direct algebraic approach? . .

a. Slight growth in the number of enemployed truck drivers is expected for the third quarter of next year but will not be at 'will not be at levels'... It's unclear what levels refers to i.e. is it the growth (e.g. 2%) or the actual number after the growth (e.g. 5 million) b. A slight growth is expected in the number of enemployed truck drivers for the third quarter of next year but will not be at Same problem as b. c. The expected number of employed truck drivers for the third quarter of next year will grow slightly, but will not be at This means that it's not the actual number that will grow but the expected number. E.g our expected number was originally 15 but this expected number has now grown to 17. d. The number of unemployed truck drivers is expected to rise in the third quarter of next year although not to I think this is accurate. The number will rise...but not to levels experienced in the last few years... e. It is expected that a slight growth in the number of unemployed truck drivers in the third quarter of next year, but will not be at It is expected that a slight growth in the number of unemployed truck drivers... implies that the slight growth is expected to do something. This begs the question, what is it that the slight growth is expected to do? It would be correct to say "It is expected that there will be a slight growth"...

No, I don't think so. have been shifted.....by earthquakes etc. implies that it is the earthquakes and other similar phenomena that have caused the shifting rather than the plates shifting by themselves. If the sentence read 'have shifted from their previous positions by earthquakes'... it would mean the plates were previously located next to the earthquakes but have since shifted to a different location. This wouldn't make any sense as earthquakes are not physical structures.

'Have' implies they shifted on their own whereas 'have been' implies that some external force shifted them

I think it's D

Average price = (total price paid)/(total dozens sold) Dozens sold in: April = x May = x June = 2x Total = 4x => Total price paid = 1.26x + 1.2x + 1.08*(2x) = 4.54x => Average price = 4.62x/4x = 1.155 ~ 1.16 Answer is D

Please check the question. There's no information on x.

Year 1: Assume total production cost in year 1 is 100. Therefore: Raw Material = 60 Processing = 40 Year 2 Raw material goes down 15% => .85 * 60 = 51 Processsing increases by 10% => 1.1 * 40 = 44 Total year 2 production cost = 51 + 44 = 95 Thus, estimated change in production cost = (95-100)/100 = 5% decrease in production cost. Answer is C.

Please confirm the wording in the question is accurate. The question and statement 1 say the same thing...

Great insight! Your method allows you to solve it in under 60 seconds.

0 is neither positive nor negative. However, it IS an integer and an even one at that. HTH

Ah, I see my mistake. If all three are equal, then they are all median. Afternoon slumber :(

I don't understand. Statement (2) gives no information on x. So x may or may not be equal to y=z. Please elaborate.

I'm getting E (1) x => x - y if x = 1 & y = 3 => z > - 2 if x = 3 & y = 1 => z > 3 Insuffcient (2) y = z x is median if x = y = z. If not, then x is not the median. Insufficient (1) & (2) (2) y = z ; (1) x-y => x-z => x Insufficient

This might be a little confusing to explain without the aid of a diagram. However, I'll give it a shot anyway. Because triangle ABC is equilateral => arc AB = arc BC = arc CA. The three of them combined make up the circumference of the circle. => Arc ABC = arc AB + arc BC = 24; => Arc AB=12=arc BC => 12 * 3 = 36 = circumference of the circle. => Pi*diameter = 36 => Diameter = 36/3.14 ~ 11
