Chapter 6, Problem 6QC

To determine

Write the temperature requirements in two ways: as a pair of simple inequalities, and as a compound inequality.

Answer to Problem 6QC

Simple inequality: $23\ge \text{t}\text{and}\text{t}\le 33$

Compound inequality: $23\le \text{t}\le 33$

Explanation of Solution

Given:

Atlantic sea turtle eggs that incubate below 23⁰C or above 33⁰C rarely hatch. Write the temperature requirements in two ways: as a pair of simple inequalities, and as a compound inequality.

Concept Used:

Let the temperature be t⁰C

The turtle eggs rarely hatched below 23⁰C or above 33⁰C.

So the eggs hatched cannot be below 23⁰C or cannot above 33⁰C

Calculation:

Simple inequality: $23\ge \text{t}\text{and}\text{t}\le 33$

Compound inequality: $23\le \text{t}\le 33$

Thus, simple inequality: $23\ge \text{t}\text{and}\text{t}\le 33$ and compound inequality: $23\le \text{t}\le 33$
