It is 160000 because 8*2 is 16 just add 0000 after the 16 
        
                    
             
        
        
        
Answer:
To find the hypotenuse you need to use the Pythagorean Theorem which is 
a^2+b^2=c^2
Where a and b are your two sides and c is your diagonal line
So you want to plug the numbers in for the right variables
5^2+12^2=c^2 
We want to find what c equals so we are first gonna simplify
25+144=c^2
we take 5^2=25, and 12^2=144, then we add them together 25+144=169
169=c^2 now you want to take 169 and square root it because the opposite of squaring is taking it by the root square
The square root of 169=13
Your hypotenuse is 13
Hope this helps ;)

Following are the answer to this question:
Step-by-step explanation:
Given:
n = 30 is the sample size.  
The mean   = 7.3 days.
 = 7.3 days.  
The standard deviation = 6.2 days.  
 df = n-1  
      
The importance level is  = 0.10
 = 0.10  
The table value is calculated with a function excel 2010:

The method for calculating the trust interval of 90 percent for the true population means is:
Formula:


It can rest assured that the true people needs that middle managers are unavailable from 5,37 to 9,23 during the years.
 
        
             
        
        
        
If <span>y = -x + 7, and (-1,y) is on the graph, then the following is true:  y=-(-1) + 7, or y=8.
Thus, y = a0 = 8.</span>
