Right off the bat (haha), we can eliminate B as an answer choice because adults are clearly part of the population; in fact, it says in the background information that their entire population is made of adults.  A population, in this context, is the group being researched.
D isn't the correct answer; the fact that adults are the target population doesn't validify anything.
C doesn't entirely prove its point because there are other factors that go into the game being biased.  In fact, I would say that this study <em>is </em>biased because the board members only attended 1 game when there are 18 teams.  Their data will only pertain to fans of the 2 teams playing each other, and not represent the population as a whole.
A would be my answer for reasons stated above.
        
                    
             
        
        
        
Answer:
$500
Step-by-step explanation:
let x = price of the dress before reductions
If the price is reduced by 60%, the price would be (100% - 60%) = 40%
Price after first reduction=  0.4x
Price after second reduction = 0.4(0.4x) 
0.16x = $80
Divide both sides by 0.16 
x = $500
 
        
             
        
        
        
Answer:
640 ft^3
Step-by-step explanation:
In this case we must divide the area into two parts, in the prism and in the pyramid, the sum of the volume of these parts would be the total volume
However
for the volume of the prism it would be the multiplication of the three sides, that is:
8 * 8 * 9 = 576
i.e. 576 ft ^ 3
For the pyramid, the formula is the multiplication of the area of the base by the height divided by 3, we know that the area of the base is 8 * 8 and that the height is 3, therefore:
8 * 8 * 3/3 = 64
64 ft ^ 3 is the volume of the pyramid
The total would be:
576 + 64 = 640
Total volume would be 640 ft ^ 3
 
        
             
        
        
        
Answer:
Thanks very much ^^
Step-by-step explanation:
 
        
                    
             
        
        
        
The answer is c 
Because if it takes 50 minutes to run 4 miles you need to divide 50/4 and you will get 12.5 and then multiply that by 30 cause she is trying to run 30 miles and that will get you 375 and then divide that by 60 cause their are 60 minutes in a hour and you will get 6.25
