Question

The temperature readings for 20 days at 8 am at a local ski resort were recorded as follows:

25,28,22,24,30,32,26,29,31,27,23,28,25,26,30,29,33,27,28,25

What was the average of recorded temperatures for these 20 days? Round your answer to the nearest tenth.

a) 27.5
b) 28.1
c) 28.5
d) 29.2

Answer 1

After adding all the recorded temperatures and dividing by 20 days, the average temperature at the local ski resort is 28.0°C when rounded to the nearest tenth.

Step-by-step explanation:

To find the average of the recorded temperatures for the 20 days, you would add up all the temperatures and then divide by the number of days. Here is the calculation step by step:

• Add up the temperatures: 25 + 28 + 22 + 24 + 30 + 32 + 26 + 29 + 31 + 27 + 23 + 28 + 25 + 26 + 30 + 29 + 33 + 27 + 28 + 25 = 559.
• Divide the sum by the number of days: 559 / 20 = 27.95.
• Since the question asks to round to the nearest tenth, the final average temperature is 28.0°C.

Therefore, option b) 28.1 is the correct answer after rounding.
