The statement that the average high temperature can be represented by 21.5/5 is false. The correct average high temperature, calculated by adding up the daily temperatures and dividing by 5, is -4.3.
The average high temperature can be found by summing up the temperatures and dividing by the number of days.
Given the high temperatures over 5 days:
Monday: -5.5
Tuesday: -4.3
Wednesday: 3.8
Thursday: -4.6
Friday: -10.9
To find the average high temperature, we need to add up these temperatures:
-5.5 + (-4.3) + 3.8 + (-4.6) + (-10.9) = -21.5
Now, we divide the sum by the number of days (5):
-21.5 / 5 = -4.3
Therefore, the average high temperature is -4.3.
The statement that the average high temperature can be represented by 21.5/5 is false.
