2-9 Study Guide and Intervention Solutions for Weighted Averages

To solve problems involving different types of values with varying importance, apply the proper method for calculating averages. Use the following steps for precise calculations:

Step 1: Start by identifying the numbers and their corresponding weights. Each value’s weight shows how much it contributes to the final result.

Step 2: Multiply each value by its respective weight. This ensures that each number contributes according to its significance.

Step 3: Add up all the products from Step 2 to get the total weighted value.

Step 4: Next, sum the weights. This gives the total weight of all the values involved.

Step 5: Finally, divide the total weighted value by the total weight. The result will give you the desired mean value based on the weights assigned to each number.

By following these steps, you can easily solve for the final weighted mean, ensuring accuracy and precision in all calculations related to varying values with different levels of importance.
