Question

find the mean of first six multiples of 5

Answer 1

First six multiples of 5 are 5,10,15,20,25 and 30.

Mean of first six multiples of 5 = Sum of observations/no.of observations

= (5+10+15+20+25+30)/6

= 105/6

= 17.5

Answer 2

Answer:

Mean of first six multiples of 5 = 17.5

Explanation:

5,10,15,20,25,30 are first six multiples of 5

/* We know that,

$\boxed {mean\\ = \frac{sum \:of\: the \:terms }{number\: of\: terms }}$*/

Now ,

$Mean(x) = \frac{5+10+15+20+25+30 }{6}$

$\implies x = \frac{105}{6}$

$\implies x = \frac{35}{2}$

$\implies x = 17.5$

Therefore,

Mean of first six multiples of 5 (x)= 17.5
