Calculating the Tolerable Range

Oct 13, 2025 by wbrum.org 110 views

Introduction

In the world of manufacturing, quality control is a crucial aspect of producing high-quality products. A company that produces square tiles is no exception. The advertised area of each tile is $100 \, \text{cm}^2$ , but there is some error in the production process. The company wants to ensure that the tiles produced differ by no more than $5\%$ from the advertised area. In this article, we will explore the mathematical concepts behind this quality control dilemma and provide a solution to ensure that the tiles meet the advertised area.

The Problem

Let's assume that the side length of the square tile is $s$ cm. The area of the tile is given by the formula $A = s^2$ . The company wants to ensure that the area of each tile differs by no more than $5\%$ from the advertised area of $100 \, \text{cm}^2$ . This means that the area of each tile should be between $95\%$ and $105\%$ of the advertised area.

Mathematically, this can be expressed as:

0.95 \times 100 \leq s^2 \leq 1.05 \times 100

Simplifying the inequality, we get:

95 \leq s^2 \leq 105

Taking the square root of both sides, we get:

\sqrt{95} \leq s \leq \sqrt{105}

Calculating the Tolerable Range

To find the tolerable range of side lengths, we need to calculate the square roots of $95$ and $105$ . Using a calculator, we get:

\sqrt{95} \approx 9.74 \, \text{cm}

\sqrt{105} \approx 10.25 \, \text{cm}

Therefore, the tolerable range of side lengths is between $9.74$ cm and $10.25$ cm.

Ensuring Quality Control

To ensure that the tiles meet the advertised area, the company can implement the following quality control measures:

Measurement: Measure the side length of each tile using a precision caliper or a micrometer.
Calculation: Calculate the area of each tile using the formula $A = s^2$ .
Verification: Verify that the area of each tile falls within the tolerable range of $95 \, \text{cm}^2$ to $105 \, \text{cm}^2$ .
Rejection: Reject any tiles that do not meet the quality control standards.

Conclusion

In conclusion, ensuring that square tiles meet the advertised area is a complex problem that requires careful consideration of the mathematical concepts involved. By implementing the quality control measures outlined above, the company can ensure that the tiles produced differ by no more than $5\%$ from the advertised area.

Future Directions

In the future, the company may want to consider implementing more advanced quality control measures, such as:

Statistical Process Control: Use statistical methods to monitor and control the production process.
Machine Learning: Use machine learning algorithms to predict the quality of the tiles based on various factors, such as the side length and the production process.
Automated Inspection: Use automated inspection systems to quickly and accurately inspect the tiles for quality.

By implementing these advanced quality control measures, the company can further improve the quality of its products and maintain its competitive edge in the market.
