Question

Calculate the mean and median of the multiples of 3 between 20 and 50

Answer 1

Answer:

21,24,27,30,33,36,39,42,45,48

$\huge{\huge{mean = \frac{sum \: of \: all \: observation}{total \: no. \: of \: all \: observation} }} \\ = \frac{21 + 24 + 27 + 30 + 33 + 36 + 39 + 42 + 45 + 48}{10} \\ = \frac{345}{10} = 34.5$

median=33

Answer 2

Answer:

Hope it will help you

Step-by-step explanation:

Mean = Total of observation

            Number of observation

= 21+24+27+30+33+36+39+42+45+48  

                        10

=345 = 34.5

   10

Median = The  middle value of number

let's arrange the number in order

=21,24,27,30,33,36,39,42,45,48

Median is the middle of the sequence = 33&36

When there are two medians we have find mean of those two

Mean = 33+36 = 69 = 34.5
