Answer:
We are 95% confident that the percentage of registered voters in the nation planning on voting for Robert Smith is between 49% and 55%.
Step-by-step explanation:
Given that :
Margin of Error = ±3%
Sample Proportion = 52%
Confidence level = 95%
The 95% confidence interval is :
Sample proportion ± margin of error
52% ± 3%
Lower boundary = 52% - 3% = 49%
Upper boundary = 52% + 3% = 55%
The interpretation is that at a given confidence level ; the popukation proportion based on the sample proportion and margin of error is in the confidence interval. 
 
        
             
        
        
        
If C is between A and B, then, we can write the equation

Substitute the value of AB and the expressions for AC and CB in terms of x.

We can now solve for x.


Dividing by 5.








 
        
             
        
        
        
The answer is 

steps 
#1) Try to leave a by itself by dividing any variable next to it

you can only divided these variables as all these variables in the original equation. are being multiplied. The opposite if multiplication is division. 
 
        
        
        
Answer:
24 degrees
Explanation: 
The total together should be 90 degrees = <2 plus <1. So if <1=66 degrees then 90-66=24
