hope it help... :)
        
             
        
        
        
To find the surface area of a pyramid, we need to find the area of all the faces and add them up. 
4 * 6 = 24
24 / 2 = 12
There are four sides (not including the base) in this pyramid, so we should multiply this by 4. 
12 * 4 = 48
Now, we find the area of the base.
6 * 6 = 36
We add up all of the numbers:
48 + 36 = 84
84 in^2 is the answer. 
Hope this helps!

Analysis of variance (ANOVA) "is used to analyze the differences among group means in a sample".  
The sum of squares "is the sum of the square of variation, where variation is defined as the spread between each individual value and the grand mean"  
If we assume that we have  groups and on each group from
 groups and on each group from  we have
 we have  individuals on each group we can define the following formulas of variation:
 individuals on each group we can define the following formulas of variation:  
 
  
 
  
 
  
And we have this property  
 
  
The degrees of freedom for the numerator on this case is given by  where k represent the number of groups.
 where k represent the number of groups.  
The degrees of freedom for the denominator on this case is given by  .
.  
And the total degrees of freedom would be  
 
And the we can find the F statistic
