Answer:
The value 10 years is the population mean
Step-by-step explanation:
A sample consists of some observations drawn from the population, so a part or a subset of the population which in this case is the number of horses with colic. 
A sample mean is the mean of the statistical samples while a population mean is the mean of the total population. 
Thus, in this case, the sample mean is the mean age of the horses with colic while the population mean age is the mean age of all the horses found at the clinic. 
Therefore, the mean age of 10 of the horses seen at the clinic would be the population mean.
 
        
             
        
        
        
Answer:
   4877 fish
Step-by-step explanation:
Each year, the fish population is multiplied by 1-6% = 0.94, so after 8 years it has been multiplied by 0.94^8 ≈ 0.609569.
At that time, the population is ...
   8000×0.609569 ≈ 4877 . . . fish
 
        
             
        
        
        
I cant give you the answer without the picture but I can tell you how to solve it.
if all the sides are the same length just multiply one of the numbers by the sides, for example, a rubics cube is 9 cm on each side. 9*6=54, so the answer would be 54 cm
 
        
                    
             
        
        
        
X= 22.5 get the x by itself by dividing by 2
        
                    
             
        
        
        
the formula for the Pythagorean theorem is a squared plus b squared is equals to c squared we don't have our a so it will be 8 * 8 =64which is 64 is equals to 10 * 10 which is 100 - 64 is equals to 36 then you square root do square roots the 36 which is 6
