Inequality Statement

The video tutorial explains the concept of inequalities using symbols such as less than, greater than, and their equal counterparts. It uses number lines to illustrate how inequalities can represent ranges of values. Three examples are provided, each demonstrating how to write inequality statements for points on a number line. The tutorial emphasizes the utility of inequalities in interpreting data.

What do inequality symbols represent?

• Subtraction of expressions

• Addition of expressions

• Inequality between expressions

• Equality between expressions

If N represents points on a number line, which inequality symbol would you use if all points are greater than or equal to a certain value?

• Less than

• Less than or equal to

• Greater than or equal to

• Greater than

What is the correct inequality statement for points on a number line that are less than or equal to 10?

• N > 10

• N < 10

• N ≤ 10

• N ≥ 10

How can you describe points on a number line that are between -10 and 7 using inequalities?

• N ≥ -10 and N ≤ 7

• N ≤ -10 and N ≥ 7

• N > -10 and N < 7

• N < -10 and N > 7

What is the benefit of using inequalities to represent groups of numbers?

• To make calculations easier

• To simplify data representation

• To increase complexity

• To avoid using variables
