Answer:
1st equation is x=11
2nd equation is ???
Step-by-step explanation:
 
        
                    
             
        
        
        
A straight line (180o) is still an angle. Would you be wondering if the question said "Can 179o be a real angle?" No you would simply draw it. 1 degree more and you have 180o and it is an angle as well. 
So you have a line that is both a line and an angle with A in the middle.

.
Step-by-step explanation:
The sample consist of 64 people and 48 of them are 'successful'. Hence, the proportion of 'successful' people is:

Where:
 - People that forms the sample, dimensionless.
 - People that forms the sample, dimensionless.
 - People classified as 'successful', dimensionless.
 - People classified as 'successful', dimensionless. 
Given that  and
 and  , the sample proportion of 'successful' people is:
, the sample proportion of 'successful' people is:


The sample proportion of 'successful' people is  .
