Answer :
The absolute value equation which could be used to obtain the greatest and least possible temperature values when the temperature reading is 17°F is (17 ± 2)°F
- Thermometer accuracy = ±2°F
- Thermometer reading = 17°F
The least possible value of temperature can be calculated thus :
- Thermometer reading - thermometer accuracy
- 17 - 2 = 15°F
The highest possible temperature can be calculated thus :
- Themometer reading - thermometer accuracy
- 17 + 2 = 19°F
Hence, the absolute value equation which represents the scenario is (17 ± 2)°F
