Question

marks scored by 10 students are 4 14 18 22 x 26 30 58 60 62 If mean is 33 find x​

Answer 1

the observations are 4,14,18,22,X,26,30,58,60,62.

mean =(4+14+18+22+X+26+30+58+60+62)/10

33=(294+X)/10

330=294+X

330-294=x

36=X

X=36..

therefore x.= 36.

hope helpsss

Answer 2

Answer:

Step-by-step explanation:

As we know the mean of number of observations is

Sum of all observations ÷ no of observation

So mean of given ten observations will be

4+14+18+22+X+26+30+58+60+62 ÷ 10

294+X ÷ 10

Now ATQ the mean of the given observations is 33

So,

294+X ÷10 = 33

294+X=330

X= 330-294

X= 36
