I believe there is only one outlier (shown in this picture) mostly because it is the farthest from this dotted mess
Answer:
2 1/3
Step-by-step explanation:
You take the first number them multiply then divide
For the first digit you are choosing from 2 digits
for the second digit you are choosing from 2 digits
for the third digit you are choosing from 2 digits
2*2*2=8
111
110
011
101
000
001
100
010
However......
A number doesn't usually start with a 0 or 0s.
Therefore, if you want 3-digit numbers and not just permutations using 0 and 1, then you must eliminate
011, 000, 001, and 010
Seeing that the first digit can't be 0, you choose from 1, then 2, and then 2 digits again; 1*2*2=4 numbers
You choose which answer best suits your problem.
Just subtitute 5 as x in the equation given for f.
2(5)+8=18.
