Answer:
<em>Definition 1: The theory, methods, and practice of forming judgments about the parameters of a population and the reliability of statistical relationships, typically on the basis of random sampling.</em>
<em>Definition 2: The use of randomization in sampling allows for the analysis of results using the methods of statistical inference. Statistical inference is based on the laws of probability, and allows analysts to infer conclusions about a given population based on results observed through random sampling. Two of the key terms in statistical inference are parameter and statistic.</em>

Answer:
   C.  168°
Step-by-step explanation:
The exterior angle at any vertex of an n-gon will be ...
   360°/n
So a 30-gon will have exterior angles of ...
   360°/30 = 12°
The adjacent interior angle is supplementary to this, so is ...
   180° -12° = 168°
_____
<em>Using the reasonableness test</em>
You know that the interior angles of a square are 90°, and that regular polygons with more sides have larger interior angles. The most any regular polygon's interior angle can be is 180°. The only answer choice between 90° and 180° is the correct choice: 168°.
 
        
             
        
        
        
Answer: 11x - xy - 6
Step-by-step explanation:
(5x+6xy-4)-(-6x+7xy+2) 
5x + 6xy - 4 + 6x - 7xy -2
11x - xy - 6
