Introduction
In mathematics, the mean of a set of numbers is calculated by adding up all the numbers and then dividing by the total count of numbers. When dealing with algebraic expressions, finding the mean involves similar steps, but with variables and constants. In this article, we will explore how to find the mean of a set of algebraic expressions, specifically the mean of , and .
Understanding the Concept of Mean
The mean of a set of numbers is a measure of the central tendency of the data. It is calculated by adding up all the numbers and then dividing by the total count of numbers. For example, if we have the numbers 2, 4, and 6, the mean would be calculated as follows:
Mean = (2 + 4 + 6) / 3 Mean = 12 / 3 Mean = 4
Applying the Concept to Algebraic Expressions
When dealing with algebraic expressions, the concept of mean remains the same. We need to add up all the expressions and then divide by the total count of expressions. In this case, we have four algebraic expressions: , and . To find the mean, we need to add up these expressions and then divide by 4.
Step 1: Add Up the Algebraic Expressions
To add up the algebraic expressions, we need to combine like terms. Like terms are terms that have the same variable raised to the same power. In this case, we have the variable raised to the power of 1 in all the expressions.
We can combine the like terms as follows:
So, the sum of the algebraic expressions is .
Step 2: Divide by the Total Count of Expressions
Now that we have the sum of the algebraic expressions, we need to divide it by the total count of expressions, which is 4.
Mean = (7t) / 4 Mean = 7t/4
Conclusion
In conclusion, the mean of , and is . This is the correct answer.
