Answer:


Step-by-step explanation:
Recall the mnemonics SOH-CAH-TOA
The sine ratio is the length of the opposite side expressed over the hypotenuse.

Take the sine inverse of both sides to get;

The cosine ratio is the length of the adjacent side expressed over the hypotenuse.

Take the cosine inverse of both sides to get;

 
        
             
        
        
        
Answer:
b. these codes are equal volume
 
        
             
        
        
        
D, because 1/4 is equivalent to 4/12 and 7/12+4/12=11/12 which is equivalent to 5/6
        
             
        
        
        
Answer:
DF = 2
Step-by-step explanation:
Formula for degree of freedom is;
DF = n - 1
Where n is sample size
In this question, political party affiliation could be Republican, Democrat, or Other. Thus, sample size is 3.
DF = 3 - 1
DF = 2
Thus, degree of freedom value would be 2
