TextBook Page 62 Question 23

One week in October in Iqaluit, Nunavut, the daily high temperatures were -4.6°C, -0.5°C, 1.2°C, 2.3°C, -1.1°C, 1.5°C, and -3.0°C. What was the mean daily high temperature that week?

To find the mean you first add every number.


Then you just simply divide the numbers to the amount of number there is.

(-4.6+-0.5+1.2+2.3+-1.1+1.5+-3.0) ÷ 7 = -0.6

Or you can Just simply do this -4.2÷7= -0.6
-4.2 is the sum of all the numbers.
