Debora [2.8K]3 years ago
8 0

Answer:

A, B, D

Step-by-step explanation:

A random sample is one in which every member of the population has an equal chance of being chosen.

If employees are chosen out of a hat, or balls are drawn from a bowl, each has an equal chance of being chosen.

Samples selected through volunteering, or where not everyone has an equal chance of being selected, is not random.

Subtraction of whole numbers is commutative. True or False
strojnjashka [21]
It is False.

If a property is commutative in subtraction it means:  x - y    is the same as y - x.

For example    5 - 3 = 2,  but 3 - 5 = -2  so subtraction is not commutative.

But 5 + 3 = 8   ,   is the same as 3 + 5 = 8.

Addition is Commutative, but Subtraction is not commutative.

So the statement that subtraction of whole numbers is commutative is False.
