Sagot :

Given Numbers:-

  • 23, 33 ,33 ,27 ,25 ,68 ,27 ,44 ,72

To Find:-

  • average of this set of numbers

Solution:-

[tex]\green{ \underline { \boxed{ \sf{Average = \frac{Sum \:of \: observation}{Number \:of \: observation}}}}} [/tex]

[tex]\longrightarrow[/tex] Here, no of observation are 9

Now,

[tex]\begin{gathered}\implies \small \sf Average =\frac{23+33+33+27+25+68+27+44+72}{9}\\\end{gathered} [/tex]

[tex]\begin{gathered}\\\implies \small \sf Average =\frac{56+60+93+71+72}{9}\\\end{gathered} [/tex]

[tex]\begin{gathered}\\\implies \sf Average =\frac{116+164+72}{9}\\\end{gathered} [/tex]

[tex]\begin{gathered}\\\implies \sf Average =\frac{352}{9}\\\end{gathered} [/tex]

[tex]\begin{gathered}\\\implies \sf Average = 39.1 \\\end{gathered}[/tex]

[tex]\longrightarrow[/tex]The Average of given set of numbers is 39.1 .

∴ Option C) is correct ✔️

Answer:

The average / mean is 39.1

Step-by-step explanation:

Numbers Given :- 23 , 33 , 33 , 27 , 25 , 68 , 27 , 44 , 72

What to do ?

  • Find the average / mean

Solution :-

What we know is ,

Formula of average :- Sum of observation / No. of observation

  • Total no. of observation :- 9

Lets do it , by putting the values we get :-

[tex] \frac{23 + 33 + 33 + 27 + 25 + 68 + 27 + 44 + 72}{9} [/tex]

[tex] = 39.1[/tex]
