Explanation of Solution
Given:
A company is manufacturing an action figure that must be at least 11.2 centimetres and at most 11.4 centimetres tall. Write and graph a compound inequality that describes how tall the action figure can be.
Concept Used:
Let the height of the action figure be x centimetre.
At least 11.2 centimetres, this means
At most 11.4 centimetres tall, this means
The compound inequality is:
Calculation:
The compound inequality is :
