Question

if the mean of the data 5,4,x,9,11,1 is 30 then find x​

Answer 1

Answer:

150

Step-by-step explanation:

sum of all other numbers is 30 so x+30/6 = 30

therefore x+30 = 180

therefore x = 150

Answer 2

Step-by-step explanation:

Mean = Sum of all numbers/Total numbers

30 = 5+4+x+9+11+1/6

30=30+x/6

30×6=30+x

180-30=x

150=x

x=150
