Answer:
The statement is false.
Step-by-step explanation:
Let a and b represent two odd integers.
The average (A) is defined by:
A=
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=
The result of the average is even, therefore the statement is false.
The previous calculation is a counterexample.
For this problem, we just have to use the values we're given to calculate the approximate value of pi.
The formula presented is
When you have a negative exponent, we can use the following property
Using this property, our problem turns out to be
Now, we just need to plug the given values on this equation
The approximated value for pi is 3.142.
