The political system most likely found with a supreme leader is a dictatorship. Hope this helps. :)
If you have samples of n 1 equals 22 and n 2 equals 20, in performing the pooled-variance t test, you have 40 degrees of freedom.
The t-test method is a method where we analyze two sets of data which both these data are independent of each other. This pooled variance test helps us in getting the overall variance in both these different sample sets when we know that both the sample sets are almost equal.
To calculate degrees of freedom, we have the formula
df = n1 +n2 -2
According to the question, n1= 22 and n2= 20
Therefore, degree of freedom= 22 +20 -2 = 40
Hence, degree of freedom is 40.

Answer:
D. anti-Assad, anti-ISIS
Explanation:
Throughout the Syrian Civil War, which started in 2011 and is still ongoing, the United States has always been in opposition to the regime of Bashar Al Assad.
The reason is that Assad's regime is pro-Russia, and Russia is one of the most important geopolitical adversaries of the United States (the other being China).
The United States also became anti-ISIS when this terrorist group emerged. The United States was crucial in the eventual almost total defeat of ISIS. Currently, ISIS only holds a small patch of land in central Syria.
The Great Society were programs developed and put forth by Democrat President L. Johnson in 1964 with the goal of eradicating poverty and racial injustices. Spending for these programs were put towards education, urban issues, health care, transportation, and poverty (present day Medicare, Medicaid, and federal funding for education).
Johnson and activists worked together to put forth studies of American socities, reported on findings to corresponding agencies, and assisted many civil rights laws including the Civil Rights law of 1964, the Voting Rights Act of 1965, The Immigration and nationality Services Act of 1965, and the Civil Rights Act of 1968.
