36 bowls - since with one gallon he can eat 12 bowls (as demonstrated by 1/12), you multiply 12 by 3 to get 36 bowls. 
 
        
                    
             
        
        
        
Answer:
He could increase the sample size
Step-by-step explanation:
In hypothesis testing, the error associated with the test is affected by a number of factors. The first factor is the level of significance, alpha. This is the probability of type 1 error. The probability of rejecting the null hypothesis when it is indeed true.
The second factor is the size of the sample used. The larger the sample, the smaller the error since the characteristics of the sample will be closer to those of the entire population on which inference is being made
 
        
                    
             
        
        
        
answer:
131.88 inches
step-by-step explanation:
- know the formula: 2πr
- now plug in what we have
2πr = circumference
2(21)(3.14)
= 131.88
 
        
             
        
        
        
Answer:
Take out the greatest common factor
The GCF is 3
3(9w^2-4)
 
        
             
        
        
        
A=number of seats in section A
B=number of seats in section B
C=number of seats in section C
We can suggest this system of equations:
A+B+C=55,000
A=B+C                                      ⇒A-B-C=0
28A+16B+12C=1,158,000
We solve this system of equations by Gauss Method.
1             1              1               55,000
1            -1            -1                         0
28         16           12          1,158,000  
1             1              1               55,000
0            -2             -2             -55,000                                    (R₂-R₁)
0           12             16           382,000                                    (28R₁-R₂)  
1            1                1              55,000
0           -2              -2             -55,000 
0            0                4               52,000                                     (6R₂+R₃) 
Therefore:
4C=52,000
C=52,000/4
C=13,000
-2B-2(13,000)=-55,000
-2B-26,000=-55,000
-2B=-55,000+26,000
-2B=-29,000
B=-29,000 / -2
B=14,500.
A + 14,500+13,000=55,000
A+27,500=55,000
A=55,000-27,500
A=27,500.
Answer: there are 27,500 seats in section A, 14,500 seats in section B and 13,000 seats in section C.
