Correct Answer
A. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.Explanation
Statement (2) alone is sufficient because it states that x is greater than 1, implying that x is a positive integer. However, statement (1) alone does not provide enough information to determine if x is positive or negative, as it only states that the absolute value of x is greater than 1, which could include negative values as well. Therefore, statement (2) alone is sufficient to answer the question, but statement (1) alone is not.Rate this question:

1 on the number line above has the lowest absolute value.
-
True
-
False
Correct Answer
A. FalseExplanation
The statement is false because the number 1 on the number line does not have the lowest absolute value. The absolute value of a number represents its distance from zero on the number line. Since 1 is further away from zero than any negative number, it does not have the lowest absolute value.Rate this question:

If x is = 20, then x2 is 100.
-
True
-
False
Correct Answer
A. FalseExplanation
The given statement is false. If x is equal to 20, then x^2 (x squared) would be equal to 400, not 100. Therefore, the correct answer is False.Rate this question:

Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
-
BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
-
EACH statement ALONE is sufficient.
-
Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data are needed.
Correct Answer
A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.Explanation
Statement (1) provides the value of y as -3. The absolute value of -3 is 3, so the value of |y| is 3.
Statement (2) does not provide any information about the value of y, so it is not sufficient to determine the value of |y|.
Therefore, statement (1) alone is sufficient to answer the question, but statement (2) alone is not sufficient.Rate this question:

-
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
-
BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
-
EACH statement ALONE is sufficient.
-
Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data are needed.
Correct Answer
A. EACH statement ALONE is sufficient.Explanation
The absolute value of b, represented as ┃b┃, is always a non-negative value. If b is negative, then ┃b┃ will be equal to -b. Therefore, in order for ┃b┃× b to be less than 2b, b must be less than 0. Statement (1) alone provides this information, so it is sufficient to answer the question. Statement (2) alone also provides the value of b as -6, which confirms that b is less than 0. Therefore, each statement alone is sufficient to answer the question.Rate this question:

If y is = -5, then y2 is 25.
-
True
-
False
Correct Answer
A. TrueExplanation
If y is equal to -5, then y^2 (y squared) would be equal to 25. This is because when you square a negative number, the result is always positive. Therefore, the statement "If y is = -5, then y^2 is 25" is true.Rate this question:

If the figure provided is drawn to scale, which of the following points on the number line above has the greatest absolute value?
-
Point A.
-
Point B.
-
Point C.
-
Point D.
-
Point E.
Correct Answer
A. Point A.Explanation
The figure provided is not visible, so it is not possible to determine the positions of the points on the number line. Therefore, an explanation cannot be provided.Rate this question:

-
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
-
BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
-
EACH statement ALONE is sufficient.
-
Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data are needed.
Correct Answer
A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.Explanation
Statement (1) states that k^3 = 27. From this, we can determine that k = 3, as 3^3 = 27. Therefore, we can determine the value of |k| to be 3.
Statement (2) alone does not provide any information about the value of k or |k|. Therefore, it is not sufficient to answer the question.
Thus, statement (1) alone is sufficient to determine the value of |k|, while statement (2) alone is not sufficient.Rate this question:
