Answer:
1.8
Step-by-step explanation:
3.6/ x for x =2
3.6/2 = 1.8
 
        
                    
             
        
        
        
It's D 4 3/8 miles
First you have to multiply 2 1/2 for the mile and 1 3/4 for the inches. You will get 4.375.Convert it to fraction which is 35/8 and simplify it to get 4 3/8.
Hope this helps!
 
        
             
        
        
        
Answer:
The test statistics is  
Step-by-step explanation:
From the question we are told that 
 The data given is  
    330 620 1870 2410 4620 6396 7822 81028309 12882 14419 16092 18384 20916 23812 25814
  The population mean is  
     The  sample  size is  n =  16
   The  null hypothesis is  
     The  alternative hypothesis is  
The sample mean is mathematically evaluated as 
   
 So 
    
=>  
The  standard deviation is mathematically represented as 
       
So 
 
    
   
=>  
   Generally the test statistic is mathematically represented as 
   

From the z-table  the p-value is  
      
  From the values obtained we see that 
          so we fail to reject the null hypothesis
  so we fail to reject the null hypothesis 
Which implies that the claim of the NarStor is wrong
 
        
             
        
        
        
Yes; you are correct.

          (x − 4) (x² <span>− 5x + 3) = 
   x * x</span>² = x³ <span>− 
   x * 5x = 5x</span>² + 
   x * 3   = 3x <span>−
   4 * x</span>²  = 4x² <span>−
   -4 * 5x =  -20x +
   -4 * 3 =  -12;

</span>          (x − 4) (x² − 5x + 3) = 
x³ − 5x² + 3x −4x² − (-20x) + (-12) ;
=  x³ − 5x² + 3x −4x² + 20x − 12 ;
= x³ − 5x² − 4x² + 3x + 20x − 12 ;
= x³ − 9x²  + 23x − 12 ;  which is:

Using the side of the square find the area:
Area = 30^2 = 900 square feet.
The rectangles area is the same, 900 square feet.
Let the width = X
The length would be 2X + 70
Area = length x width
X * 2x+ 70 = 900
This expands to 2x^2 * 70x = 900
Use the quadratic formula to solve for x:
-70 +/- sqrt(70^2-4*2(-900))/2*2
X = 10
Width = x = 10 feet
Length = 2x + 70 = 90 feet
