Answer:
the simplified expression is: 6y-7x
Step-by-step explanation:
-y+7y= 6y
            -7x
            = 6y-7x
 
        
             
        
        
        
The answer is the positive square root of 36
        
                    
             
        
        
        
Answer:
The degrees of freedom is 11.
The proportion in a t-distribution less than -1.4 is 0.095.
Step-by-step explanation:
The complete question is:
Use a t-distribution to answer this question. Assume the samples are random samples from distributions that are reasonably normally distributed, and that a t-statistic will be used for inference about the difference in sample means. State the degrees of freedom used. Find the proportion in a t-distribution less than -1.4  if the samples have sizes 1 = 12 and n 2 = 12 . Enter the exact answer for the degrees of freedom and round your answer for the area to three decimal places. degrees of freedom = Enter your answer; degrees of freedom proportion = Enter your answer; proportion
Solution:
The information provided is:

Compute the degrees of freedom as follows:

    
Thus, the degrees of freedom is 11.
Compute the proportion in a t-distribution less than -1.4 as follows:

                       
*Use a <em>t</em>-table.
Thus, the proportion in a t-distribution less than -1.4 is 0.095.
