A. Mean

Mean = Total / How many numbers there are

City A- Add all the numbers:

4 + 3.5 + 5 + 5.5 + 4 + 2 = 24

24 / 6 = 4

Mean = 4 for City A

City B- Mean:

Add all the numbers:

5 + 6 + 3.5 + 5.5 + 4 + 6 = 30

There are 6 numbers.

30 / 6 = 5

Mean = 5 for City B

B. MAD(Don't know this part)

C. Median

City A- Median:

There are 2 middle numbers.

They are 5 and 5.5

5 + 5.5 = 10.5

Median = 5.25 for City A

City B- Median:

Find the least common denominator for these two rational expressions.
lbvjy [14]
\frac{y}{y^{2}-1},\ \frac{y}{y^{2}-8y+7}
=\frac{y}{(y-1)(y+1)},\ \frac{y}{(y-1)(y-7)}
=\frac{y(y-7)}{(y-1)(y+1)(y-7)},\ \frac{y(y+1)}{(y-1)(y+1)(y-7)}

So the common denominator is (y-1)(y+1)(y-7)

Percent change = ((new value) - (old value))/(old value) × 100%
  = (3710 - 6000)/6000 × 100%
  = -38.16%

The decrease in circulation is about 38%.
