Answer:

Arithmetic mean of  [tex]1,\frac{1}{2}, \frac{1}{3} ,\frac{1}{4} ,\frac{1}{5}[/tex]  is  [tex]\frac{137}{300}[/tex] .

Step-by-step explanation:

To find : arithmetic mean of given data.

Given data : [tex]1,\frac{1}{2}, \frac{1}{3} ,\frac{1}{4} ,\frac{1}{5}[/tex]

Solution :

• Average is the arithmetic mean.
• It is the ratio of sum of all the numbers given in data to the total number of observations.
• Formula: [tex]Average \ or\ mean =\frac{\text { sum of all the observations }}{\text { total of observations }}[/tex]
• Here, sum of observations [tex]= 1 + \frac{1}{2} + \frac{1}{3} +\frac{1}{4} + \frac{1}{5}[/tex]

                                                     [tex]= \frac{137}{60}[/tex]      

• Total number of observations [tex]= 5[/tex]
• Substituting values in above formula,
• [tex]$Average \ or \ mean = \frac{\frac{137}{60} }{5}$[/tex]

                                     [tex]= \frac{137}{60\times 5} \\\\= \frac{137}{300}[/tex]
