The correct answer to this open question is the following.
Although there are no options attached, we can say the following.
Under the United States Constitution, the concept of federalism means that there is a division of powers between state and national governments,.
Under this constitutional division, the country is governed by one federal government and state governments. They have a direct relationship and sometimes they have encountered some conflicts due to the application of legislation. 
The federal government is dived into three branches. The executive branch is the President of the United States. The legislative branch that is the Congres divided into two chambers. The upper chamber or Senate, and the lower chamber or House of Representatives. And finally, the judicial power that is the US Supreme Justice. 
These three branches work under the system of checks and balances, which means that none of the three have more power than the others.
The states have a similar structure. 
 
        
             
        
        
        
For a randomly selected screen monitor, the probability that the selected monitor will have a screen defect is 0.04.
<u>Explanation:</u>
μPˆd = 0.04
n = 100
mean = 0.04 multiply with 100 = 4
A mean is the basic scientific normal of a lot of at least two numbers. The mean for a given arrangement of numbers can be figured in more than one way, including the number-crunching mean strategy, which utilizes the whole of the numbers in the arrangement, and the geometric mean technique, which is the normal of a lot of items. In any case, the entirety of the essential strategies for processing a straightforward normal produces the equivalent inexact outcome more often than not.  
The mean is the numerical normal of a lot of at least two numbers. The math mean and the geometric mean is two sorts of implications that can be determined. Adding the numbers in a set and separating by the absolute number gives you the number-crunching mean. The geometric mean is progressively convoluted and includes duplication of the numbers taking the nth root.
