The average body temperature of a lemming is 98.6 degrees Fahrenheit. The
temperature is considered abnormal if it is more than 1.5 degrees above or below that.
Write the absolute value inequality that represents this.

Answer:

[tex]|x - 98.6| > 1.5[/tex]

Step-by-step explanation:

Given

Temperature = 98.6F

Range = 1.5F

Required

Write the absolute value inequality

Let the temperature be represented by x

We start by writing an expression for the difference between x and 98.6.

This can be written as x - 98.6

From the question, we understand that this difference is more than 1.5F

Representing this using absolute value inequality; we have

[tex]|x - 98.6| > 1.5[/tex]

Solving further; this gives

[tex]x - 98.6 > 1.5[/tex] or [tex]x - 98.6 < -1.5[/tex]

Make x the subject of formula in both cases

[tex]x >98.6 +1.5[/tex] or [tex]x < 98.6-1.5[/tex]

[tex]x >100.1[/tex] or [tex]x < 97.1[/tex]

This can be rewritten as

[tex]x >100.1[/tex] or [tex]97.1>x[/tex]

Combining these two inequalities;

[tex]97.1 > x > 100.1[/tex]

Hence;

The absolute inequality is  [tex]|x - 98.6| > 1.5[/tex]

And the range of value is [tex]97.1 > x > 100.1[/tex]
