x=3
From equation 1
3+y=4
y=1
Answer: The mean is 3.5. The range is 7. The median is 3, and finally the mode is 4.
Since we know that percentages and decimals go by decimal place we can solve this. For Example, 10% is just 0.1, so if we apply this to the questions we can solve them
1) 49%
2)16%
3) Equal
4)12%
5)1.2
6)31/50
7)50 1/4
8)1/8
