### Educational Exercise: Finding the Mean and Analyzing Pie Charts

#### Problem 1:
Ten students in Mrs. Smith's math class took a state-sponsored aptitude test. Their math scores were reported to Mrs. Smith as follows:
- 585, 490, 354, 348, 542, 341, 342, 552, 482, and 470.

**Question:** Find the mean score. Round your answer to one decimal place if necessary.

#### Problem 2:
**Multiple Choice:**
Choose the one alternative that best completes the statement or answers the question.

**Use the circle graph to solve the problem:**

A survey of the 6629 vehicles on the campus of State University yielded the following circle graph:

- **Motorcycles:** 10%
- **Hatchbacks:** (percentage not visible but represented in the graph)
- **Convertibles:** (percentage not visible but represented in the graph)
- **SUVs:** (percentage not visible but represented in the graph)
  
**Question:** Based on this data, determine the number of motorcycles on campus.

##### Steps to Solve:
1. Calculate the number of motorcycles by using the percentage provided in the graph.
2. Percentage of motorcycles = 10%
3. Total number of vehicles = 6629

**Calculation:** 
\[ \text{Number of motorcycles} = \frac{10}{100} \times 6629 = 662.9 \]
Therefore, the campus has approximately 663 motorcycles.

This exercise provides a good example of calculating the mean and using pie charts to interpret data. Please ensure you validate the pie chart values visually if the percentages of other vehicle types become visible.
