Answer:
 
    
 
    
For this case the confidence interval is given by :

Step-by-step explanation:
Data provided
 represent the sample mean for the fuel efficiencies
 represent the sample mean for the fuel efficiencies
 population mean
 population mean 
s=2.51 represent the sample standard deviation
n=601 represent the sample size  
Confidence interval
The formula for the confidence interval of the true mean is given by:
 (1)
   (1)
The degrees of freedom for this case is given by:
 
The Confidence level for this case is 0.95 or 95%, and the significance level  and
 and  and the critical value is given by
 and the critical value is given by  
Replcing into the formula for the confidence interval is given by:
 
    
 
    
For this case the confidence interval is given by :

 
        
             
        
        
        
3x - 4y = 8
y = mx + b ; m is the slope ; b is the y-intercept
-4y = -3x + 8
y = -3x/-4 + 8/-4
<u>y = 3/4 x - 2</u>
Need to check if the given choices have the same slope.
3x + 4y = -8
4y = -3x - 8
y = -3/4 x - 8/4 = -3/4 x - 2
6x - 8y = 12
-8y = -6x  + 12
y = -6/-8 x + 12/-8
y = 3/4 x - 1 1/2
9x - 12y = 24   This equation would cause a consistent-dependent system
-12y = -9x + 24
y = -9/-12 x + 24/-12
<u>y = 3/4 x - 2</u>  
16x + 12y = -10
12y = -16x - 10
y = -16/12 x - 10/12
y = -1 1/3 x - 5/6
        
                    
             
        
        
        
Multiply the first bracket by -2
Multiply the second bracket by 2
x-3-12+4x= 4x-10
- negative number times + positive number= - negative number
- negative number times -negative number = + positive number
x+ 4x-3-12= 4x-10
5x-15= 4x-10
Move 4x to the other side 
5x-4x-15= 4x-4x-10
x-15= -10
Move -15 to the other side
x-15+15= -10+15
x= 5 
Answer : x= 5 
 
        
                    
             
        
        
        
Answer:
The value of the hypotenuse is 69.77 meters.
Step-by-step explanation:
To determine, in triangle RG, the value of its hypotenuse if its sides measure 63 meters and 30 meters, the following calculation must be performed, applying the Pythagorean theorem:
63 ^ 2 + 30 ^ 2 = X ^ 2
3969 + 900 = X ^ 2
√ 4869 = X
69.77 = X
Therefore, the value of the hypotenuse is 69.77 meters.
