Answer 1

hopefully its helped u:)

Answer 2

Answer:

Required arithmetic mean is 52.83.

Step-by-step explanation:

Given all numbers are 42,56,36,41,86,56.

Here we want to find arithmetic mean.

But now question is how can we find Arithmetic mean ?

We know, Arithmetic mean $= \frac{sum \: of \: numbers}{total \: numbers}$

By two examples we can understand this concept easily,

Example -1:

We are taking 4 numbers 20,25,30 and 35.

So arithmetic mean of 20,25,30 and 35

$= \frac{20 + 25 + 30 + 35}{4} \\ = \frac{110}{4} \\ = 27.5$

Example -2:

We are taking 8 numbers 2,4,6,8,10,12,14,16.

So, arithmetic mean of 2,4,6,8,10,12,14,16

$\frac{2 + 4 + 6 + 8 + 10 + 12 + 14 + 16}{8} \\ = \frac{72}{8} \\ = 9$

Here given 6 numbers are 42,56,36,41,86,56.

So by rule arithmetic mean

$= \frac{42 + 56 + 36 + 41 + 86 + 56}{6} \\ = \frac{317}{6} \\ = 52.83$
