Question

Mean of the data 45,35,20,30,15,25,40 is

Answer 1

Mean of the given data is 30

Step-by-step explanation:

let we have numbers a1, a2 ... an

the mean can be written as

mean = a1 + a2 +...+ an/N

N= total number

from given data we can write

N = 7

mean = 45+35+20+30+15+25+40/7

mean = 30

Mean of the given data is 30

Answer 2

$\large \tt Mean = \frac{45 + 35 + 20 + 30 + 15 + 25 + 40}{7} = \frac{210}{7} = 30$
