4. Determine whether the statement is true or false. Prove the statement directly from the definition if it is true, and give a

natta225 [31]

Answer:

The statement is false.

Step-by-step explanation:

Let a and b represent two odd integers.

The average (A) is defined by:

A= $\frac{a+b}{2}$

In order to prove the statement, you have to show that it's true for all odd integers. But, to disprove it, you just have to find a counterexample where the statement is false.

Notice that it is easier to try to find a counterexample.

For example, a=3 and b=5

A= $\frac{3+5}{2} = \frac{8}{2} = 4$

The result of the average is even, therefore the statement is false.

The previous calculation is a counterexample.
