If
1 gallon = $1.40
12.6 gallons = $1.40 × 12.6
Plug those into your calculator and you'll get $17.64!
        
                    
             
        
        
        
Here is the answer all you have to do is go 1984 divide by 42 47.23809524
        
             
        
        
        
Answer:
The standard error of the mean is 4.5.
Step-by-step explanation:
As we don't know the standard deviation of the population, we can estimate the standard error of the mean from the standard deviation of the sample as:

The sample is [30mins, 40 mins, 60 mins, 80 mins, 20 mins, 85 mins]. The size of the sample is n=6.
The mean of the sample is: 

The standard deviation of the sample is calculated as:

Then, we can calculate the standard error of the mean as:

 
        
             
        
        
        
Answer:
8 OR -8 OR Both
Step-by-step explanation:
-2 x 4 = -8
-8 x -8 x -8 = -64
Square root = 8 OR -8
1 to the 9th power = 1
-8 / 1 = -8
8/1 = 8
Hope that helps!
