Answer:
<h2>"None of the statements are true".</h2>
Step-by-step explanation:
Let's examine each statement.
<h3>"The product of two numbers with the same sign is negative".</h3>
This statement is completely false, because they rule states that two number with the same sign as a positive product.
<h3>"The quotient of a positive dividend and a negative divisor is positive".</h3>
This statement is false, because they rule states that the quotient between number with different signs is negative.
<h3>"The quotient of 0 and a positive number is undefined".</h3>
This statement is also false, because the undefined quotient is when a number is divided by 0, not the opposite way. In this case, such quotient is just zero.
As you can observe, none of the statements are true.
Therefore, the right answer is "None of the statements are true".
