Average Calculation for Given Numbers
To find the average (or mean) of a set of numbers, you add all the numbers together and then divide by the total count of numbers in the set.
Numbers Provided
The numbers given in the question are: 308, 125, 45, 120, and 102.
Average Formula
The formula to calculate the average is:
$$ \text{Average} = \frac{\text{Sum of all observations}}{\text{Number of observations}} $$
Step 1: Sum the Numbers
First, we need to calculate the sum of all the given numbers:
$$ 308 + 125 + 45 + 120 + 102 = 700 $$
Step 2: Count the Numbers
Next, we count how many numbers are in the list. There are 5 numbers in total.
Step 3: Calculate the Average
Now, we apply the average formula using the sum we found and the count of numbers:
$$ \text{Average} = \frac{700}{5} $$
Performing the division:
$$ \text{Average} = 140 $$
Result
Therefore, the average of the numbers 308, 125, 45, 120, and 102 is 140.
