Question

During a week in January in Cleveland, Ohio, the daily high temperatures were -4 °F, -2 °F, -12 °F, 5 °F, 12 °F, 16 °F, and 20 °F. Which expression can be used to find the difference between the highest temperature of the week and the lowest temperature of the week?

Answer 1

`\Delta T = T_(max,w) - T_(min,w)`

`\Delta T = 20\,^(\circ)F - (-12\,^(\circ)F)`

`\Delta T = 32\,^(\circ)F`

Explanation:

The expression needed is the highest temperature of the week subtracted by the lowest temperature of the week. That is to say:

`\Delta T = T_(max,w) - T_(min,w)`

`\Delta T = 20\,^(\circ)F - (-12\,^(\circ)F)`

`\Delta T = 32\,^(\circ)F`
