Answer:
The average temperatures were:
- New York City: 63
- San Francisco: 64
Explanation:
Remember that, the average is obtained in the form below:
- Average = The sum of all the values / the number of values.
In this case, the number of values is 12 because are the number of months in the year. The sum of values is shown below for each case:
- Average temperature in New York City = (39 + 42 + 50 + 61 + 71 + 81 + 85 + 84 + 76 + 65 + 55 + 47) / 12 = 63.
- Average temperature in San Francisco = (57 + 60 + 62 + 63 + 64 + 67 + 67 + 68 + 70 + 69 + 63 + 58) / 12 = 64.
I don't add units because the table doesn't specify if they are Celsius, Fahrenheit, or others.
