Answer: 18 degrees
Step-by-step explanation:
To get the mean add up all of the values that you are given and divided it by how many there are.
Week One:
The values added up to 364 I then divided 364 by 7 to get a mean value of 52.
Week Two:
The values added up to 490, I then divided 490 by 7 to get a mean value of 70.
(In the above problems, I divided by 7 because there are 7 temperatures given)
I then subtracted 70 and 52 and got 18 degrees greater during week two.
