Answer:
Step-by-step explanation:
volume = area of base * height = area of base * 9 = 72 
-> area of base = 72/9 = 8 
let a,b,c be the length of sides of isosceles right triangle base
we have a = b and a*b/2 = 8 ft2
-> a*a/2 = 8ft2
-> a*a = 16 
-> a=4ft=b 
have c^2 = a^2 + b^2 = 16 +16 = 32 
-> c =  = 5.656 ft
 = 5.656 ft
Since i dont know that is DF, i calculate both a,b and c 
 
        
                    
             
        
        
        
Answer:
It cannot be further simplified
Step-by-step explanation:
11 is a prime number, so there are no numbers that can go into 14 and 11 (besides 1 and 1 would not simplify the problem) 
 
        
             
        
        
        
Answer:
a) Null hypothesis: 
  
Alternative hypothesis: 
  
b)  
  
The degrees of freedom are given by:

The p value for this case taking in count the alternative hypothesis would be:
 
  
Step-by-step explanation:
Information given
 represent the sample mean for the amount spent each shopper
 represent the sample mean for the amount spent each shopper
 represent the sample standard deviation
 represent the sample standard deviation 
 sample size
 sample size  
 represent the value to verify
 represent the value to verify
t would represent the statistic    
 represent the p value f
 represent the p value f
Part a
We want to verify if the shoppers participating in the loyalty program spent more on average than typical shoppers, the system of hypothesis would be:  
Null hypothesis: 
  
Alternative hypothesis: 
  
The statistic for this case would be given by:
 (1)
 (1)  
Replacing the info given we got:
 
  
The degrees of freedom are given by:

The p value for this case taking in count the alternative hypothesis would be:
