An absolute value inequality to describe this situation will be
| 2.5 ≤ W ≤ 11.5 |
An absolute value can be a value of any variable which will always be non - negative value.
Given that an average birth weight of a new born baby is 7 pounds. However, this weight can vary as much as 4.5 pounds. This means the weight can be
7 + 4.5 = 11.5
or
7 - 4.5 = 2.5
If W = average birth weight of a new born baby which is 7 pounds
Therefore, an absolute value inequality to describe this situation will be
| 2.5 ≤ W ≤ 11.5 |
