To determine

To model: Situations that differ both inequalities.

Answer to Problem 6LC

  $x\ge 0$ , marks scored in a test

  $x>0$ , number of persons attended a meeting

Explanation of Solution

Given information: The inequalities are $x\ge 0$ and $x>0$

Model situation: we need to model the situations that differ both the inequalities

Let x be the marks scored by a student, $x\ge 0$ . Mark scored can be 0 or greater than 0.

Let x be the number of persons attended a meeting. When no persons attended, then meeting will not be held. So x cannot be 0. $x>0$

  $x\ge 0$ , marks scored in a test

  $x>0$ , number of persons attended a meeting
