Introduction

The town of Newburg has a total of 1,200 students, with a significant portion of them walking to school and the rest taking the bus. To visualize this data, a grid has been created, where blue squares represent students who walk to school and white squares represent those who take the bus. In this article, we will delve into the world of mathematics to analyze and describe this grid, using at least two mathematical concepts to provide a deeper understanding of the data.

Understanding the Grid

The grid consists of 1200 squares, with 12 rows and 100 columns. The blue squares represent students who walk to school, while the white squares represent those who take the bus. To begin our analysis, let's consider the concept of proportional reasoning. Proportional reasoning is the ability to understand and compare the relationships between different quantities. In this case, we can use proportional reasoning to determine the proportion of students who walk to school and those who take the bus.

Calculating Proportions

To calculate the proportions, we need to determine the number of blue squares (students who walk to school) and the number of white squares (students who take the bus). Let's assume that the grid is a 12x100 grid, with each square representing a student. We can calculate the number of blue squares as follows:

Number of blue squares = 12 rows x 50 columns (assuming 50% of students walk to school) = 600

Similarly, we can calculate the number of white squares as follows:

Number of white squares = 12 rows x 50 columns (assuming 50% of students take the bus) = 600

Now that we have the number of blue and white squares, we can calculate the proportions as follows:

Proportion of students who walk to school = (Number of blue squares / Total number of squares) x 100
Proportion of students who take the bus = (Number of white squares / Total number of squares) x 100

Using the values we calculated earlier, we can determine the proportions as follows:

Proportion of students who walk to school = (600 / 1200) x 100 = 50%
Proportion of students who take the bus = (600 / 1200) x 100 = 50%

Using Ratios to Compare Data

Another mathematical concept that can be applied to this grid is the concept of ratios. Ratios are used to compare the relationships between different quantities. In this case, we can use ratios to compare the number of students who walk to school and those who take the bus.

Let's assume that we want to compare the number of students who walk to school in different age groups. We can use ratios to compare the number of students who walk to school in each age group. For example, let's assume that we have the following data:

Age Group	Number of Students Who Walk to School
5-10	150
11-15	200
16-20	250

We can use ratios to compare the number of students who walk to school in each age group as follows:

Ratio of students who walk to school in the 5-10 age group = 150 / 600
Ratio of students who walk to school in the 11-15 age group = 200 / 600
Ratio of students who walk to school in the 16-20 age group = 250 / 600

Using these ratios, we can compare the number of students who walk to school in each age group and determine which age group has the highest proportion of students who walk to school.

Using Graphs to Visualize Data

Another mathematical concept that can be applied to this grid is the concept of graphing. Graphing is the process of creating a visual representation of data. In this case, we can use graphs to visualize the number of students who walk to school and those who take the bus.

Let's assume that we want to create a graph to show the number of students who walk to school and those who take the bus in different age groups. We can use a bar graph to compare the number of students who walk to school and those who take the bus in each age group. For example, let's assume that we have the following data:

Age Group	Number of Students Who Walk to School	Number of Students Who Take the Bus
5-10	150	150
11-15	200	200
16-20	250	250

We can use a bar graph to compare the number of students who walk to school and those who take the bus in each age group as follows:

Bar graph with two bars for each age group, one for the number of students who walk to school and one for the number of students who take the bus

Using this graph, we can visualize the number of students who walk to school and those who take the bus in each age group and determine which age group has the highest proportion of students who walk to school.

Conclusion

In conclusion, the town of Newburg's grid provides a unique opportunity to apply mathematical concepts to real-world data. By using proportional reasoning, ratios, and graphing, we can gain a deeper understanding of the data and make informed decisions. The grid can be used to compare the number of students who walk to school and those who take the bus in different age groups, and to determine which age group has the highest proportion of students who walk to school. By applying mathematical concepts to real-world data, we can gain a better understanding of the world around us and make more informed decisions.
