Question

Consider the following word problem: The temperature readings for 20 days at 3 PM at a local ski resort were recorded as follows: 27 ° 10 ° 18 ° 20 ° 8 ° 22 ° 13 ° -8 ° 27 ° 4 ° -4 ° -10 ° 3 ° 18 ° 20 ° 6 ° 20 ° 19 ° 26 ° 10 ° What was the average of the recorded temperatures for these 20 days? Round your answer to the nearest tenth.

Answer 1

To find the average of the recorded temperatures, add up all the temperatures and divide the sum by the total number of temperatures. The average of the recorded temperatures for these 20 days is 15.0°C.

Step-by-step explanation:

To find the average of the recorded temperatures, you need to add up all the temperatures and then divide the sum by the total number of temperatures.

Here are the steps:

1. Add up all the temperatures: 27 + 10 + 18 + 20 + 8 + 22 + 13 + (-8) + 27 + 4 + (-4) + (-10) + 3 + 18 + 20 + 6 + 20 + 19 + 26 + 10 = 299.
2. Divide the sum by the total number of temperatures (20): 299 / 20 = 14.95°C.
3. Round the answer to the nearest tenth: 14.95 rounds to 15.0°C.

Therefore, the average of the recorded temperatures for these 20 days is 15.0°C.
