Question

7. If the mean of 16, 14. X. 23,20 is 18, find the value of x.​

Answer 1

Answer:

17

Explanation:

See Mean= Sum of all observation

No of observation

Now

Sum of obs = 16+14+x+20+23 = 73+x

Total no. of observation= 5

Now,

18 = 73+x/ 5

This implies__

18×5 = 73 +x

90=73+x

90-73 = x

17 = X

Answer 2

Answer:

x=17

Explanation:

mean=16+14+x+23+20 /5

given mean is 18.so

18= 16+14+x+23+20 /5

18= 16+14+17+23+20 /5                                  (90/5=18)

x=17
