Final answer:
To find the number that is five units to the right of -2 on a number line, add 5 to -2, which equals 3. This illustrates that understanding the number line is essential for integer operations and concepts like standard deviation.
Step-by-step explanation:
To find a number that is five units to the right of -2 on a number line, you simply add 5 to -2. The calculation would be: -2 + 5 = 3. Therefore, the number you are looking for is 3, which is five units to the right of -2 on the number line.
When working with the number line, remember that moving to the right indicates an increase, while moving to the left indicates a decrease. This concept is not only applicable to finding positions on the number line but also relates to rules of integer operations such as addition, subtraction, and understanding standard deviations in statistics.
