Determine whether the set is well defined. 1) The set of manufacturers of televisions that enjoyed sizeable profits in 1996
A) not well defined
B) well defined

A) not well defined

Step-by-step explanation:

A set is said to be a well-defined set when we can clearly state whether something belongs to that set or not without any trace of ambiguity.

This implies that based on the information provided, we can easily decide on the members of a well defined set. A set that is not well defined carries some level of ambiguity regarding what and what should be part of the set.

In this case, 'sizeable profits' was not clearly defined. There ought to have been a threshold of profit defined as sizeable (e.g profit of $ 1,200,000 and above).

Since there is no such definition of 'sizeable profits', the set is not well defined.

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
