Question

5. Average (missing value). The temperature at the top of Mt. Hood in Oregon was recorded for 5 straight days. For the first four days, the temperatures were 32°, 30°, 22°, and 10°, but a researcher lost the value of day #5. If the average temperature over the 5 days was 19.8°F, what is the missing temperature of day #5?

Answer 1

5°F

Explanation:

Given that the average is obtained from;

Average = sum of scores / number of scores

Average temperature = 19.8°F

Let the temperature of the fifth day be x

Hence;

19.8 = 32 + 30 + 22 + 10 + x/5

19.8 = 94 + x/5

x= (5×19.8) -94

x= 5°F
