Question

What is the average of the 3 temperatures -50°C, -20°C, and 15°C?

Answer 1

See explanation.

Explanation:

To calculate the mean of the 3 numbers you have to add them and then divide the result by `3`:

`bar(x)=(-50+(-20)+15)/3=-55/3=-18 1/3`

Answer: The mean value (temperature) is `-18 1/3` degrees
