Question

If the mean of 41,32,30,27, 28,42,35,X is 33, find the value of x.​

Answer 1

X=29

solution,

Summation FX=41+32+30+27+28+42+35+X=235+X

N(total number of items)=8

Mean=33

Now,

`mean = (summation \: fx)/(n) \\ \: \: or \: 33 = (235 + x)/(8) \\ or \: 33 * 8 = 235 + x \\ or \: 264 = 235 + x \\ or \: - x = 235 - 264 \\ or \: - x = - 29 \\ x = 29`

Hope this helps...

Good luck on your assignment..

Answer 2

x = 29.

Explanation:

There are a total of 8 numbers so if 33 is the mean then the total value is 33*8

= 264.

So 41+32+30+27+28+42+35+X = 264

235 + X = 264

X = 264 - 235

= 29.
