x+2
Step-by-step explanation:
The firs 3 observations are x, x+2, x+4
Mean = sum of data/samaple size
Mean = x+x+2+x+4/3
MEan = 3x+6/3
Mean = 3(x+2)/3
Mean = x+2
Hence the required mean is x+2
39. It is divisible by 3 so it isn't prime.
Total ribbons would be the sum of two numbers.
So, x = 29 + 17 = 46
In short, Your Answer would be: 46 ribbons
