Answer:
[tex]\displaystyle 3x[/tex]
Step-by-step explanation:
Mean is equal to the sum of terms divided by the number of terms.
[tex]\displaystyle \frac{x+2x+3x+4x+5x}{5}[/tex]
[tex]\displaystyle \frac{15x}{5}[/tex]
Mean = 3x
Mean = [tex]\frac{SumOfObservations}{No. OfObservations}[/tex]
Mean = [tex]\frac{x+2x+3x+4x+5x}{5}[/tex]
Mean = [tex]\frac{15x}{5}[/tex]
