Answer: 
percentile rank of x =
number of values before x                           100
---------------------------------------------------  x    ----------
number of total values on the dot plot         1
Step-by-step explanation:
you divide the number of values before x over the number of total values on the dot plot, and divide the quotient by 100 to get your percentile. 
 
        
             
        
        
        
Good afternoon/evening. 
-4^4 = four to the fourth power = (-4)(-4)(-4)(-4) = 256
Remember, when a negative is multiplied by a negative it equals a positive.  
        
             
        
        
        
By definition, two angles are supplementary if the sum of them is 180 degrees. In this case (see figure attached with the answer) the line AD is transversal to lines AB and DC. This is a proof of the Same-side interior angle theorem.
This theorem states that if we have two lines that are parallel and we intercept those two lines with a line that is transversal to both, same-side interior angles are formed, and also sum 180º, in other words, they are supplementary angles.
Then:
By the definition of a parallelogram, AB∥DC. AD is a transversal between these sides, so ∠A and ∠D are <em><u>same-side interior angles</u></em>. Because AB and DC are <em><u>parallel</u></em>, the same-side interior angles must be <em><u>supplementary</u></em> by the same-side interior angles theorem. Therefore, ∠A and ∠D are supplementary.
 
        
                    
             
        
        
        
Answer:
799
Step-by-step explanation:
Let x = the hundreds digit
Let y = the ones digit
x = y-2
We want to maximize x and y.  The both have to be single digit numbers
Rewriting this
x+2 =y
The largest x can be is 7 if y is a single digit
x is 7 and y is 9
We can pick the tens digit.  Make it as big as possible to make out number as large as possible
799
