Hello, I have appled to the following universities for Masters in telecommunication program , can anybody guide me which school is the best. -University of Houston -UT Dallas -UT Arlington. Thank you.

in which program you have applied in university of houston , I have applied in the electrical engineering program and they told me that they will tell me about the decision after 15th march 2004 for the fall 2004 , anyways if you are applying as an international student it may take more time to answer.

Hello , does anyone have information about the electrical engineering program of Lamar University Texas?If so Please respond me ,how good it is!!!!! I appreciate your responses.Thank you.

thursday is the correct answer

Q: on jan 23 1603 it was tuesday , then what will be the day on jan 25 2003?

Find the number of triangles in an octagon. (1) 326 (2) 120 (3) 56 (4) Cannot be determined here I want to share formula with you: nC3 where n is the number of n-gon that is for octagon number of triangles will be 8C3 that is 56:)

Each interior angle of a regular polygon is 120 degrees greater than each exterior angle. How many sides are there in the polygon? highlight to see the answer=12.

hello truman : 2^2x + 2^2x=2*2^x not 4^2x, think of 2^a+2^b

your explanation is lucid! thanks.

nice explanation Austin TX

i think rumen it should be 2^99 according to the power rule,coerrect me if I am wrong and according to me the answer shuold be 49.5or 99/2.

can you please explain this expression and your sol as well, thank you.

goto supervoca.com and download antonym s/w for GRE , thats very good tool for practicing your vocab and try to diversify your list ,donot stick with barron but also lood hit parades in other books like word smart 1 and 2 , kaplan hit list etc. hope it helps.

is it 101?

hello, watch out the following link it contains some fruitful attacking strategies for quant section: http://www.txstate.edu/slac/gre/gremath7/gremath7.htm thank you.

for the 3rd one: If A and B are independent, then the probability that events A and B both occur is p(A and B) = p(A) × p(B). In other words, the probability of A and B both occurring is the product of the probability of A and the probability of B. What is the probability that a coin will come up with heads twice in a row? Two events must occur: a heads on the first toss and a heads on the second toss. Since the probability of each event is 1/2, the probability of both events is: 1/2 × 1/2 = 1/4. Now consider a similar problem: someone draws a card at random out of a deck, replaces it, and then draws another card at random. What is the probability that the first card is the ace of clubs and the second card is a club (any club)? Since there is only one ace of clubs in the deck, the probability of the first event is 1/52. Since 13/52 = 1/4 of the deck is composed of clubs, the probability of the second event is 1/4. Therefore, the probability of both events is 1/52 × 1/4 = 1/208. What's the probability of A and B (2 of 2) if A and B are not independent? If A and B are not independent, then the probability of A and B is p(A and B) = p(A) × p(B|A) where p(B|A) is the conditional probability of B given A. If someone draws a card at random from a deck and then, without replacing the first card, draws a second card, what is the probability that both cards will be aces? Event A is that the first card is an ace. Since 4 of the 52 cards are aces, p(A) = 4/52 = 1/13. Given that the first card is an ace, what is the probability that the second card will be an ace as well? Of the 51 remaining cards, 3 are aces. Therefore, p(B|A) = 3/51 = 1/17, and the probability of A and B is 1/13 × 1/17 = 1/221.

for the q2: I think its a straightforward 10C4 formula according to which the answer is 210. am I correct?

hello truman, sol(1): as the question says that the number should be odd and does not contain the integer 5 : so we have only 4 unit digits as 5 as an odd is eliminated so we have only 4 odd digits left ; we have 9 tens digits and lastly we have 8 thousand digits(eliminating 5 and 0) therefore we we can have 4*9*8=288 three digit numbers (positive).

Q:Of a group of people surveyed in a political poll, 60 percent said that they would vote for candidate R. Of those who said they would vote for R. 90 percent actually voted for R. and of those who did not say that they would vote for R. 5 percent actually voted for R. What percent of the group voted for R? (A) 56% (B) 59% © 62% (D) 65% (E) 74% explain your approach!

yes you can simplify it!

If you put $100 in a bank account that pays you 10% interest, compounded annually, how many years would it take you to attain a balance of more than $200, assuming no withdrawals were made? a 5 b 6 c 7 d 8 e 9 the answer is obviously d but can anybody solve by some faster approach like just setting up an equation for these kind of yr finding problem in compound interests.i have found an equation for the above ques which is: 100 (1.1^x) > 200. but dont know how can anybody explain and solve this equation.Thanks in advance.

thanks anony for your expl.
