Answer:
mode = 8
Step-by-step explanation:
Find the value of x by using the average formula, that is
[tex]\frac{x+2x+2x+6+3x-1+4x-8}{5}[/tex] = 9
[tex]\frac{12x-3}{5}[/tex] = 9 ( multiply both sides by 5 )
12x - 3 = 45 ( add 3 to both sides )
12x = 48 ( divide both sides by 12 )
x = 4
The set of 5 numbers is
4, 8, 14, 11, 8
The mode is the value in the set which occurs most
mode = 8
