Answer:
-5 degrees Fahrenheit
Explanation:
The Fahrenheit temperature readings taken at 2 hour intervals on a winter day were 8°, 6°, 2°, 0°, -1°, -4°, -7°, and -9°. To find the temperature of the 8 readings, we need to add them together.
8 + 6 + 2 + 0 + (-1) + (-4) + (-7) + (-9) = -5
Therefore, the temperature of the 8 readings is -5 degrees Fahrenheit.
In summary, the temperature readings taken at 2 hour intervals on a winter day were added together to find their total. The sum of these temperatures is -5 degrees Fahrenheit.
