We can learn a lot about a population if we select a subset of it.
<h3>What is a subset?</h3>
One kind of set is a sample space. It is a clear listing of every event that could occur in a statistical experiment. A statistical experiment's events are a subset of the sample space.
A subset is a smaller group of results that are part of the bigger group.
Subsets are events, and events are subsets. A subset is an event of a sample space, and an event is a potential result of an experiment. A random experiment's sample space is a set (S) that contains all of the experiment's potential outcomes.

Answer:
x = 12
Step-by-step explanation:
The mistake made here is in making 130 = 9x + 7. They are not the same. 
The central angle = 130 degrees.
Any angle sharing the endpoints of the central angle and having it's vertex on the same side of the central angle is 1/2 the central angle.
1/2 the central angle = 130 /2 = 65
Cyclic quadrilaterals (those with all 4 points touching a circle's circumference) have opposite angles  supplementary.
65 + 9x + 7 = 180           Combine like terms on the left
72 + 9x = 180                 Subtract 72 from both sides
72 - 72 + 9x = 180-72     Combine
9x = 108                          Divide by 9
9x/9 = 108/9                   
x = 12
   
 
        
                    
             
        
        
        
X•2+12 I’m not sure if that’s what you’re looking for though
