To answer this item, find first the z-score of the given data.
    z-score = (x - m) / d
where x is data point, m is the mean and d is the standard deviation
Substituting the given values,
    z-score = (188 - 176.7) / 9.9  = 1.14
This translates to a percentage of 87.29%. 
Because we are asked of the percentage of those with height greater than this, that would be,
     100 - 87.29% = 12.71%
Answer: 12.71%
        
             
        
        
        
To solve you can use inverse operations. 
Here are the steps to find the answer:
1. Write out the equation: -6(x-2)+3x= -3(x+3) +21
2. Distribute both sides: -6x+12+3x= -3x-9+21
3. Simplify both sides: -3x+12=-3x+12
4. This equation is true for all values, or infinity, because the equation is the same on both sides
Let me know if you need further explanation. I hope this helps.
