2,2,2,2,3,5,7,9,9,10,11,12,18 find the median
Natasha2012 [34]
Answer:
median = 7
Step-by-step explanation:
The median is the middle value of the data set arranged in ascending order
2, 2, 2, 2, 3, 5, 7, 9, 9, 10, 11, 12, 18
↑ middle value
median = 7
Take y2-y1 over x2-x1 to get the slope of the line
2-5/2-6
-3/-4
3/4
We're going to solve each of the systems to determine the solution.
