answer is 28

Answer is E

Answer is A B says Considerably more than 20 percent of drivers and front-seat passengers in Dole County always wear seat belts when traveling by car. But the stimulus says auto not car ............auto would include cars as well as vans , SUV etc........... and statistically its A

Opponents of laws that require automobile drivers and passengers to wear seat belts argue that in a free society people have the right to take risks as long as the people do not harm others as a result of taking the risks. As a result, they conclude that it should be each person’s decision whether or not to wear a seat belt. Which of the following, if true, most seriously weakens the conclusion drawn above? (A) Many new cars are built with seat belts that automatically fasten when someone sits in the front seat. (B) Automobile insurance rates for all automobile owners are higher because of the need to pay for the increased injuries or deaths of people not wearing seat belts. © Passengers in airplanes are required to wear seat belts during takeoffs and landings. (D) The rate of automobile fatalities in states that do not have mandatory seat-belt laws is greater than the rate of fatalities in states that do have such laws. (E) In automobile accidents, a greater number of passengers who do not wear seat belts are injured than are passengers who do wear seat belts The answer is B Why B ? Opponents of laws that require automobile drivers and passengers to wear seat belts argue that in a free society people have the right to take risks as long as the people do not harm others as a result of taking the risks. As a result, they conclude that it should be each person’s decision whether or not to wear a seat belt. what if by not wearing seat belts ...people cause some harm to the other ..that is what B says so it is the best out of the given lot so the answer is B

Answer is B In (I) We get XX or X>Y But from (II) we get Y>X so its sufficient

New area = 9

ans = A 3^4n+2 = 3^2(2n+1)= 9^(2n+1) or odd powers of 9 so 9^odd power +1 is divisible by 10 , hence A

F and J cannot stand in one place , because of that either J is in front of F or behind F Total no. of possibilities = 720 , but half the time F is behind J ( the question specifically says that F need not be just behind J) so ans= 720/2 = 360

ans = 34

answer is A since you know the function for X and Y
