Concept explainers
Whether the statement “To find the additive inverse of a set of numbers, find the sum of the numbers and then divide by the number of items in the set.” is true or false. If false, replace the underline word.
Answer to Problem 9SGR
The given statement is false. To find the mean of a set of numbers, find the sum of the numbers and then divide by the number of items in the set.
Explanation of Solution
An integer and its opposite are also called additive inverses of each other.
The additive inverse of a number is the same number with an opposite sign and the additive identity is 0. The additive inverse cannot be finding by addition of numbers. It should be mean.
Mean is the sum of numbers divide by the number of items in the stet
To obtain the mean of a set of numbers, find the sum of the numbers and then divide by the number of items in the set.
Example:
The mean of 1,2,3,4 and 5 is calculated as,
Thus, the given statement is false. To find the mean of a set of numbers, find the sum of the numbers and then divide by the number of items in the set.
