**Exams.cpp: Understanding Weighted Averages** This example illustrates how to calculate weighted averages using a series of test scores. ### Test Scores and Weighted Average Calculation **Scores:** - **Test 1:** 60, 50, ..., 55 - **Test 2:** 70, 60, ..., 65 - **Test 3:** 80, 70, ..., 75 - **Test 4:** 90, 80, ..., 84 #### Calculation for Weighted Average: - The formula for calculating the weighted average is: \[ 0.1(60) + 0.25(70) + 0.3(80) + 0.35(90) \] - Breakdown of calculation: \[ = 6 + 17.5 + 24 + 31.5 = 79.0 \] - **Weighted Averages:** - First four scores yield a weighted average of **79.0**. - Further, a weighted average of **69** is calculated using other series of scores. - Another set yields a weighted average of **73.65**. ### Averages Calculation for Each Test: 1. **Test 1:** 2. **Test 2:** 3. **Test 3:** 4. **Test 4:** ### Additional Instructions You should sum up all scores for test one and divide by ten to compute its unweighted average. Repeat this procedure for test two, test three, and test four. This process results in four unweighted averages. This example aids in understanding how weights impact overall performance in a series of assessments, crucial for educational evaluations.

**Problem 7: Exams.cpp** A teacher assigns weights to four exams: 10%, 25%, 30%, and 35% respectively. The task is to write a program that processes ten sets of four grades each. The program should calculate and print: 1. The weighted average of each set of grades. 2. The unweighted average for each exam across all sets. A global constant should be used to define the number of student sets. --- There are no graphs or diagrams in the image to describe.
