Hola!
Here's your answer
Mean = Sum of observations / total number of observations
Total number of observations - 4
Therefore,
7 + 4 + x + 10 / 4 = 8
21 + x / 4 = 8
21 + x = 8 × 4
21 + x = 32
Thus,
x = 32 - 21
x = 11
Value of x = 11
Hope it helps!

Answer:
the answer is 11
Step-by-step explanation:
mean= sum of observations/ no. of observations
given mean is 8 and the numbers are 7,4,x,10
8=7+4+x+10/4
take 4 to LHS side
8×4=21+x
32=21+x
take 21 to RHS side
32-21=x
x=11
