Answer:

The Average Temperature for the week is -1°C

Step-by-step explanation:

First to find the average, you have to combine all the numbers

-3-4+0-2+0+3-1 = -7

Then you have to divide the total, with the number of numbers used to combine to make the total

-7 ÷ 7 = -1

The average temperature is -1°C

Tina’s answer may be inaccurate because she only asked ten of her neighbors, when in reality she wanted the results of her entire state. In order to get accurate results, Tina needs to ask many more people.
