Answer:
n = 13
Step-by-step explanation:
The sum of the measures of the interior angles of an n-sided polygon is
(n - 2)180
Set (n - 2)180 equal to 1980 and solve for n.
(n - 2)180 = 1980
Divide both sides by 180.
n - 2 = 11
Add 2 to both sides.
n = 13
A. Mean
Mean = Total / How many numbers there are
City A- Add all the numbers:
4 + 3.5 + 5 + 5.5 + 4 + 2 = 24
There are 6 numbers.
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
10.5 / 2 = 5.25
Median = 5.25 for City A
City B- Median:
The 2 middle numbers are 3.5 and 5.5
3.5 + 5.5 = 9
9 / 2 = 4.5
Median = 4.5 for City B.
Answers:
a. The mean for City A is 4. The median for City B is 5.
b. Don't know MAD
c. The median for City A is 5.25. The median for City B is 4.5

Answer:
a. B. Frequency is the number of times a particular distinct value occurs. Relative frequency is the ratio of the frequency of a value to the total number of observations.
b. A. A relative frequency is the same as a percentage expressed as a decimal.
Step-by-step explanation:
Frequency is the number of repetitions of a particular observation.
Relative Frequency is the ratio of the frequency of particular observation to the sum of frequencies of all the observations.
The percentage is the proportion of the whole.
Thus, In question (a)
Option B is the only correct answer.
and in question (b)
Option A is the only correct answer.
