The mean of the data set is 26 because the sum of all the data points divided by the number of data points is 26.4 repeating which rounds to 26.
I believe it's 36. The vertices have the same x coordinate so I found the difference between the y coordinates.
Answer:
x=3
Step-by-step explanation:
The equation here is x=3. If it were y=3, then it would be a horizontal line.
Answer:
3 || 3

12 || 21
In the first column, we see the numbers increasing by +3, serially.
In the second column, we see the numbers increasing by +6, serially.
