Answer:
I think they are independent
Step-by-step explanation:
 
        
             
        
        
        
The parameter of a rectangle can be alculated using the following rule:
parameter = 2(length + width)
from the givens: 
length = 13 inches
width = 10 inches
so, just substitute with the givens in the equation to calculate the parameter:
parameter = 2(10+13) = 2*23 = 46 inches
        
             
        
        
        
1. D - Since it's random, everyone has an equal chance of being picked
2. B - Since the people are already registered voters it would be easier to get a response from them. Plus, picking ever 10th person makes it random.
3. false - a fair question wouldn't make assumptions about the population 
4. B - "Don't you think" causes the answerer to be pushed towards saying yes
hope this helps :)
 
        
             
        
        
        
To rearrange the equation given, we need to take note the rules in adding, subtracting, multiplying and dividing terms. We rearrange the equation as follows:
<span>((a+b/c)(d-e)=f) 1/(d-e)
</span>(a+b/c = f/(d-e))c
a+b = fc/(d-e)
a = [fc/(d-e)] - b
Hope this answers the question.
