Answer:
the answer is 7
Step-by-step explanation:
the right angle is 90° 
90-55=35
35÷5=7
 
        
                    
             
        
        
        
Here are the combinations:
1x18 = 18
18x1 = 18
9x2 = 18
2x9 = 18
6x3 = 18
3x6 = 18
        
                    
             
        
        
        
W=4
JG=12
This is the answer

Answer:
99% CI:

Step-by-step explanation:
We have to calculate a 99%CI for the difference of means for the vegan and the omnivore.
First, we have to estimate the standard deviation

The MSE can be calculated as

The weighted sample size nh can be calculated as

The standard deviation then becomes

The z-value for a 99% confidence interval is z=2.58.
The difference between means is

Then the confidence interval can be constructed as
