Answer:
37
Step-by-step explanation:
To find the average, you need to add all the numbers in the set and divide that value by the total amount of numbers there are,
We already know that the average of the set of temperatures is 40,
Since there are 5 different days with temperatures, multiply 40 by 5,
40 × 5
= 200
200 is what all the temperatures should equal once they are added up,
Now add 40, 39, 44, and 40 together,
40 + 39 + 44 + 40
= 163
Now subtract 163 from 200,
200 - 163
= 37
Therefore the temperature that was recorded on the fifth day was 37f.
