  1. Quantitative Interview questions and answers

    Haven't learned probability that much, please correct me if I am wrong. #4, draw a diameter such that it can always group 2 points onto a simicircle, the 3rd point must be either one, so the answer is 1/2.
  2. Quantitative Interview questions and answers

    Drowsy, You still have to prove 0.11111... = 1/9. Here it is: assume 0.999... = a 10 x 0.999... = 10a 9.999... = 10a 9.999... - a = 10a - a 9 = 9a a=1 thus, 0.999... = 1 Sorry, didn't see your long division note. Yes, elementary math just shows that. But we just memorize it, the whatever...
  3. Quantitative Interview questions and answers

    #3 solution: draw a horizontal line, suppose minute hand at origin 0, then hour hand 60 units(or *miles*, you define it) ahead. hour hand travels at the 1/12 speed as minute hand does. Both start the same time, at some time they will meet at a point ahead. The distance minute hand travels will...
  4. Quantitative Interview questions and answers

    Hi all! Haven't visited Quantent for a long time. Having a quick look at the questions, #1 and #6 are basically the same. To be honest, I did something like them in my junior high. #1 answer: 2^(1/2), (don't know how to use radical sign, i.e., 1.414...) #6 answer: 2 similar question: prove...

  8. Alcohol use helps boost income: study

    The author is making a point which is not supported subsequently, or I would say the point is conceptually converted. The content itself is quite good. I absolutely agree that socializing will benefit your capital. However, the major point there is "Socializing", Not "Acohol consumption"...
  9. Alcohol use helps boost income: study

    I don't really buy this, or it could happen to be true. But you don't really need *STUDIES*. Using very simple probability, Alcohol comsumers have approx. 50% chances to earn more than non-alcohol consumers(there is a very rare chance that they will equal). Sometimes some companies just hire...
  10. Remembering 9/11

    I was in Long Island. I used to take train to work and there was nothing new when the N train was running over the M bridge. When I got back to my company, everybody was watching the TV. It was just like a movie. I called my sister immediately because she was working in Deutsche bank, one...

    Thanks Andy. I think I am going to get a new laptop and erase everything on the HD. By the way, Thinkpad is good but expensive. I know a guy who used to work for a computer magazine that rated computers. Every year all computer vendors sent a lot of servers, PCs and laptops to them for...
  14. dual boot

    Has anyone ever tried installing a dual boot system with Linux and WinXP? I plan to get a laptop and get those two installed.
  15. Question on MFE Admission

    Thanks Andy, I found this site because I was curious about how good this program is so I googled "Mathematics on Finance in Baruch". Without that much effort I got that on google. You can try that and it shows up probably the 2nd or the 3rd in the list. I've been following the program...
