Answer:
The product of two numbers is negative. Which statement is true? Select TWO answers.
A. The quotient of the two numbers is positive.
B. The quotient of the two numbers is negative.
C. No conclusion can be drawn about the quotient.
D. The signs of both numbers are negative.
E. The sign of one number is positive and the sign of the other is negative.
Step-by-step explanation:
The correct two options are B (the quotient of the two number is negative) and E (the sign of one number is positive and the sign of the other is negative).
To validate Option B; quotient is the result we get when we divide two numbers. For instance:
To validate Option E; multiplying two number of opposite sign will give us negative sign. For instance:

Explanation:
The key states
It means that a stem of 7 and leaf of 4 combine to the value 74
We're interested in scores greater than 90, so we'll be focusing on the stems of 9 and 10 only
- Stem 9. Leaves 1,2,3,4,6,7.
- Stem 10. Leaf 0
Stem9 has 6 leaves while stem10 has 1 leaf. That's 6+1 = 7 leaves total, which means we have 7 scores above 90. If there was a leaf of 0 for stem9, then we'd have to ignore it (since it forms the score 90). But we don't have to worry about that for this case.
