Question

If the mean of 1,2,3,4+x is 2 then find x

Answer 1

Step-by-step explanation:

total no=4 ,

mean=2

mean=1+2+3+4+x/4=2

10+x/4=2

10+x=8

x=8-10=-2

x=-2

Answer 2

Answer:

X=(-6)

Step-by-step explanation:

mean=sum of all observations/total no of observations

0=1+2+3+x/4

0=6+X/4

(if u transpose 4 to the other side it will come in multiplication so 4×0=0)

0=6+X

X=(-6)
