Answer: 10 minutes 
Step-by-step explanation:
First you have to find out how big the tank is. You will have to you the formula Length x Width x Height. 20 x 18 x 10= 3,600 in. Then you would divide that by 360. 3,600/360= 10. It would have to take 10 minutes to empty the aquarium. 
 
        
             
        
        
        
Answer:
d
Step-by-step explanation:
 
        
             
        
        
        
A 95% confidence  interval on the z-table is 1.96.
Now find the standard error using the formula: standard deviation /  square root sample size: 
0.7 / √100 = 0.07
Multiply to the confidence interval: 1.96 x 0.07 = 0.137 = 0.14
Now add and subtract tot he average weight:
14 - 0.14 = 13.86
14 + 0.14 = 14.14
The answer is 13.96 ≤ u ≤ 14.14
