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.

You run 4 3/4 miles through a park each day. If you ran that distance 5 times last week, how many miles did you run?

It;s simple you just take 4 3/4 and multiply it by 5
which is 23 3/4 or 23.75

\cfrac{2}{10^4}-\cfrac{1}{10^5}\implies \cfrac{(10\cdot 2)~-~(1\cdot 1)}{10^5}\implies \cfrac{20-1}{10^5}\implies \cfrac{19}{10^5}
\\\\\\
19\cdot \cfrac{1}{10^5}\implies 19\times 10^{-5}$
