MULTIPLE CHOICE A thermometer is
pav-90 [236]

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

<u>The least possible value of </u><u>temperature</u><u> </u><u>can</u><u> </u><u>be</u><u> </u><u>calculated</u><u> </u><u>thus</u> :

  • Thermometer reading - thermometer accuracy

  • 17 - 2 = 15°F

<u>The highest possible </u><u>temperature</u><u> </u><u>can</u><u> </u><u>be</u><u> </u><u>calculated</u> thus :

  • Themometer reading - thermometer accuracy

  • 17 + 2 = 19°F

Hence, the absolute value equation which represents the scenario is (17 ± 2)°F
