Worksheet 6 of 10 (55% complete)
Question 1
Question: Is x > y?
Statement (1): x² > y²
Statement (2): x³ > y³
Statement (1): x² > y² means |x| > |y|, but x could be less than y if both negative - insufficient. Statement (2): x³ > y³ means x > y (cubing preserves inequality) - sufficient.
Question 2
Question: Is xy > 0?
Statement (1): x > 0
Statement (2): y > 0
xy > 0 means x and y have same sign. Each alone insufficient, together they are both positive → product positive.
Question 3
Question: Is x > 0?
Statement (1): x² > 0
Statement (2): x³ > 0
Statement (1): x² > 0 means x ≠ 0, but x could be positive or negative - insufficient. Statement (2): x³ > 0 means x must be positive - sufficient.
Question 4
Question: Is x > y?
Statement (1): x² > y²
Statement (2): x³ > y³
Statement (1): x² > y² means |x| > |y|, but x could be less than y if both negative - insufficient. Statement (2): x³ > y³ means x > y (cubing preserves inequality) - sufficient.
Question 5
Question: Is x > 0?
Statement (1): x² > 0
Statement (2): x³ > 0
Statement (1): x² > 0 means x ≠ 0, but x could be positive or negative - insufficient. Statement (2): x³ > 0 means x must be positive - sufficient.
Question 6
Question: Is x > y?
Statement (1): x² > y²
Statement (2): x³ > y³
Statement (1): x² > y² means |x| > |y|, but x could be less than y if both negative - insufficient. Statement (2): x³ > y³ means x > y (cubing preserves inequality) - sufficient.
Question 7
Question: Is x > 0?
Statement (1): x² > 0
Statement (2): x³ > 0
Statement (1): x² > 0 means x ≠ 0, but x could be positive or negative - insufficient. Statement (2): x³ > 0 means x must be positive - sufficient.
Question 8
Question: Is x > 0?
Statement (1): x² > 0
Statement (2): x³ > 0
Statement (1): x² > 0 means x ≠ 0, but x could be positive or negative - insufficient. Statement (2): x³ > 0 means x must be positive - sufficient.
Question 9
Question: Is xy > 0?
Statement (1): x > 0
Statement (2): y > 0
xy > 0 means x and y have same sign. Each alone insufficient, together they are both positive → product positive.
Question 10
Question: Is x > y?
Statement (1): x² > y²
Statement (2): x³ > y³
Statement (1): x² > y² means |x| > |y|, but x could be less than y if both negative - insufficient. Statement (2): x³ > y³ means x > y (cubing preserves inequality) - sufficient.
Question 11
Question: Is xy > 0?
Statement (1): x > 0
Statement (2): y > 0
xy > 0 means x and y have same sign. Each alone insufficient, together they are both positive → product positive.
Question 12
Question: Is x > 0?
Statement (1): x² > 0
Statement (2): x³ > 0
Statement (1): x² > 0 means x ≠ 0, but x could be positive or negative - insufficient. Statement (2): x³ > 0 means x must be positive - sufficient.
Question 13
Question: Is x > 0?
Statement (1): x² > 0
Statement (2): x³ > 0
Statement (1): x² > 0 means x ≠ 0, but x could be positive or negative - insufficient. Statement (2): x³ > 0 means x must be positive - sufficient.
Question 14
Question: Is xy > 0?
Statement (1): x > 0
Statement (2): y > 0
xy > 0 means x and y have same sign. Each alone insufficient, together they are both positive → product positive.
Question 15
Question: Is xy > 0?
Statement (1): x > 0
Statement (2): y > 0
xy > 0 means x and y have same sign. Each alone insufficient, together they are both positive → product positive.
Question 16
Question: Is x > 0?
Statement (1): x² > 0
Statement (2): x³ > 0
Statement (1): x² > 0 means x ≠ 0, but x could be positive or negative - insufficient. Statement (2): x³ > 0 means x must be positive - sufficient.
Question 17
Question: Is xy > 0?
Statement (1): x > 0
Statement (2): y > 0
xy > 0 means x and y have same sign. Each alone insufficient, together they are both positive → product positive.
Question 18
Question: Is xy > 0?
Statement (1): x > 0
Statement (2): y > 0
xy > 0 means x and y have same sign. Each alone insufficient, together they are both positive → product positive.
Question 19
Question: Is xy > 0?
Statement (1): x > 0
Statement (2): y > 0
xy > 0 means x and y have same sign. Each alone insufficient, together they are both positive → product positive.
Question 20
Question: Is x > y?
Statement (1): x² > y²
Statement (2): x³ > y³
Statement (1): x² > y² means |x| > |y|, but x could be less than y if both negative - insufficient. Statement (2): x³ > y³ means x > y (cubing preserves inequality) - sufficient.
