Answer: [tex]\dfrac{\text{171+x}}{\text{2}}[/tex]
Step-by-step explanation:
We know that the average of any n observations is given by :-
[tex]\text{Average}=\dfrac{\text{Sum of observations}}{\text{Number of observations}}[/tex]
The given observations : x and 171
Sum of observations : [tex]x+171[/tex]
Number of observations : 2
Now, the average of 171 and x is given by :-
[tex]\text{Average}=\dfrac{\text{171+x}}{\text{2}}[/tex]
Hence, the expression represents the average of 171 and x is [tex]\dfrac{\text{171+x}}{\text{2}}[/tex].
