Answer:
The null hypothesis will not be rejected.
Step-by-step explanation:
The hypothesis for the test is:
<em>H</em>₀: There is no difference between the two population means, i.e. <em>d</em> = 0.
<em>Hₐ</em>: There is a significant difference between the two population means, i.e. <em>d</em> ≠ 0.
Consider the Excel output attached.
The mean of the differences is,  .
.
The standard deviation of the differences is,  .
.
Compute the test statistic as follows:

The degrees of freedom is, n - 1 = 7.
Compute the <em>p</em>-value as follows:

The decision rule is:
The null hypothesis will be rejected if the p-value of the test is less than the significance level.
<em>p</em>-value = 0.112 > α = 0.02.
The null hypothesis will not be rejected.
 
        
             
        
        
        
To find the factor a a polynomial from its roots, we are going to seat each one of the roots equal to

, and then we are going to factor backwards.
We know for our problem that one of the roots of our polynomial is -3, so lets set -3 equal to

 and factor backwards:



 is a factor of our polynomial.
We also know that another root of our polynomial is 

, so lets set 

 equal to 

 and factor backwards:




(

 is a factor of our polynomial.
We can conclude that there is no correct answer in your given choices.
 
        
        
        
Answer:
10
Step-by-step explanation:
14+14+18+18+22=86
6*16=96
96-86=10
 
        
                    
             
        
        
        
Step-by-step explanation:
Solving
2x + 6 = 4x - 4
Bringing like terms on one side 
6 + 4 = 4x - 2x
10 = 2x 
10 / 2 = x 
5 = x
