Given the mean and most of the set data, please find the missing value of x in each set. a) {3,5,6,8,9,2,1,0,5,x}; mean = 4
b) {6,7,2,9,4,x); mean = 5

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
