Correct me if wrong but value of |x| = always x regardless of whether x is +ve or -ve since it only measures distance of x from 0. So answer choice for Q7 would be A.

If x^2+5y = 49, is y an integer? (a) 1 (b) x^2 is an integer OA is: However, I chose .

Please post the OA.

Could you please clarify the question. Is it k2-k and not k^2-k or anything else?

Simplifying the question, x+y^2 = (x+y^2)^2; 1=x+y^2 Using (a) x=y^2, on the above equation we get 1=2y^2 or y^2 = 1/2, this give only one answer y=1/Sqrt(2) For (b) xy^2=0, Multiply 1=x+y^2 on both sides by y^2 This gives, y^2=xy^2+y^4 which translates to y^2=y^4 ie y^2=1 Now y can be +1 or -1 Therefore, answer choice should be A

Is 0 considered a multiple of 5 [x-2=0, when x=2]? I think I went wrong there. Otherwise only 7 would have fulfilled both conditions.

Is x a prime number? (a) x (b) (x-2) is a multiple of 5 OA: Could someone explain the answer choice?

My apologies. I posted the question in the wrong section.

Is x a prime number? (a) x (b) (x-2) is a multiple of 5 OA: Could someone explain the answer choice?

But isn't Choice C stated in the passage?

One major obligation of the social psycholoigst is to provide his own discipline, other social sciences as well as laymen with conceptual tools that will increase the range and reliability of their understanding of social phenomena. Beyond that, responsible government officials are today turning more frequently to the social scientist for insights into the nature and solution of the problems with which they are confronted. The above argument assumes that: (a) Social psychologists must have a strong background in other science as well as their own. (b) A study of social psychology should be a part of the curriculum of government officials. © The social scientist has an obligation to provide the means by which social phenomena may be understood by others. (d) Social phenomena are little understood by those outside of field of social psychology. (e) A good social psychologist is obligated principally by the need to solve inter-disciplinary problems. OA: Could someone please explain the answer choice?

Usually, in comparing qualities of 2 similar things, the words -that of & those of are used.

Could someone please clarify the context in which to use the following words in sentences. I have not been able to find a suitable explanation anywhere else. (a) If versus whether (b) Who versus whom © From versus than

If both sides of the x^4*y^2>x^2*y^4 are divided by x^2*y^2 we get Choice B.
