Question

find the mean and median of first 7 multiples of 4
​

Answer 1

Answer:

Seven multiples of 4 are:

4,8,12,16,20,24,28

Mean= 4+8+12+16+20+24+28/7

=112/7

=16

Median=(n+1/2)th term

n=7

=(7+1/2)th term

=(8/2)th term

=4th term

Mean is 16

Median is 4th term =16

Hope it helps you!

Answer 2

Answer:

please mark me as the brainliest

Step-by-step explanation:

The first 7 multiples of 4 are 4 , 8 , 12 , 16 , 20 , 24 , 28

mean = sum of all observations / total number of observations

= (4 + 8 + 12 + 16 + 20 + 24 + 28) / 7

= 112 / 7

mean = 16

since total number of observations is n = 7 , which is an odd number

so, median = [ ( n + 1 ) / 2 ] th term

= [ ( 7 + 1 ) / 2 ] th term

= ( 8 / 2 ) th term

= 4 th term

median = 16
