Median is 23 because it comes in middle of five numbers
To find the mean, add up the values in the data set and then divide by the number of values that you added
if we sum these numbers we get 100 then divide it by 5 we get
100/5 = 20
Answer:
x=12
Step-by-step explanation:
use midpoint theorem that said that the small line segment (3x+11) is half of the segment ( 9x -14)
2(3x +11) = 9x -14
6x +22 = 9x -14; distribute
6x -9x = -22-14; subtract 9x and 22 from both sides
-3x = -36; divide both sides by -3
x= 12
