　　Explanation

　　1.The correct answer is C

　　Let stand for the number of students who belong to both clubs. The members of the math club can be broken down into two groups: those who are in both clubs (there are students in this category) and those who are in the math club only (there are students in this category).

　　The members of the chess club can also be broken down into two groups: students who are in both clubs and students who are in the chess club only.

　　Since a total of students belong to only one of the two clubs, you know that . Solving this equation gives , so students belong to both clubs

　　2.The correct answer is C

　　In order for to satisfy , it must be true that and are equal to each other and not equal to zero. An example of such a pair is , which is in quadrant .

　　In quadrant , all the values are negative and all the values are positive, so in quadrant , and cannot be equal. For example, the pair does not satisfy the condition, since , not .

　　In quadrant , the values and the values are both negative, so it is possible for and to be equal. For example, the pair is in quadrant and .

　　In quadrant , and cannot be equal because the values are positive and the values are negative. For example, the pair does not satisfy the condition, since .

　　The quadrants that contain pairs that satisfy the given condition are quadrants and only.

　　3.The correct answer is C

　　Recall that percent means out of every , or out of every . The question asks for an equivalent ratio: out of how many. The ratio out of can be reduced (by dividing both members by ) to out of .

　　4.The correct answer is D

　　To determine the probability that a senior&aposs name will be chosen, you must determine the total number of seniors&apos names that are in the lottery and divide this number by the total number of names in the lottery. Since each senior&aposs name is placed in the lottery times, there are seniors&apos names. Likewise, there are juniors&apos names and sophomores&apos names in the lottery. The probability that a senior&aposs name will be chosen is .

　　5.The correct answer is C

　　The fact thatfor all values ofmeans that the pointis the maximum of the quadratic function, somust be the vertex of the parabola. The parabola intersects the-axis at the pointsand, somust be halfway betweenand. Therore,. Of the choices, the only one with-coordinate equal tois. Therore,could be the coordinates of point.
