Find the mean. 5) Ten students in Mrs. Smith's math class took a state sponsored aptitude test. Their math scores were reported to Mrs. Smith: 585, 490, 354, 348, 542, 341, 342, 552, 482, and 470. Find the mean score. Round your answer to one decimal place if necessary.
Percentage
A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.
Algebraic Expressions
In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.
Numbers
Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.
Subtraction
Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.
Addition
Before we begin to understand the addition of algebraic expressions, we need to list out a few things that form the basis of algebra.

### 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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa2e51798-56c9-44d1-aa6f-1c7e97773f8d%2Fc485f8d4-4c1e-40e7-83af-cfb460c1179d%2Fzed1m_processed.jpeg&w=3840&q=75)
