anonymous · Answer

(96+68+79+85+x)/5 = 84
(96+68+79+85+x)= 84*5
328+x =420
so, x= 92

anonymous · Answer

so fifth score is 92

anonymous · Answer

remember that the average is the sum of the terms divided by the number of the times.
Since the number of terms is 5. we have
84=total/5
thus total=420
and 420= 96+68+79+85+x = 328+x
and so x=92
