Question

(1, 2, 3, 4, 5, 6, 7)... Set M is shown above. Each number in set N is gener- ated by dividing each number in set M by 2. What is the average (arithmetic mean) of the numbers in set N ?

1

3/2

7/4

2

4

Answer 1

2

Explanation:

First, you have to divide each of the numbers in set M to get set N.

Set N is... (0.5, 1, 1.5, 2, 2.5, 3, 3.5)

Now, we can find the average of the set by adding all the numbers together and dividing by the number of elements in the set.

0.5 + 1 + 1.5 + 2 + 2.5 + 3 +3.5 = 14

14/7 = 2

The mean of the numbers in set N is two.
