Answer:
100 meters per minute
Step-by-step explanation:
Find his average speed by dividing the distance he walked by the number of minutes it took him:
500/5
= 100
So, his average speed was 100 meters per minute 
 
        
                    
             
        
        
        
Subract the entrance cost from $35 and then divide what’s left to see how many games he must play
        
                    
             
        
        
        
Complete Question 
A survey is planned to estimate the proportion of voters who support a proposed gun control law. The estimate should be within a margin of error of ±5% with 90% confidence, and we do not have any prior knowledge about the proportion who might support the law. How many people need to be included in the sample?
Round your answer up to the nearest integer.
sample size = _____
Answer:
The sample size is  
     
Step-by-step explanation:
From the question we are told that  
    The margin of error is  E = 5% = 0.05
 Generally given that there was no prior knowledge about the proportion of who might support the law, we will assume the sample proportion to be  
      
From the question we are told the confidence level is  90% , hence the level of significance is    
        
=>    
Generally from the normal distribution table the critical value  of   is
 is  
     
Generally the sample size is mathematically represented as  
     ![n = [\frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * \^ p (1 - \^ p )](https://tex.z-dn.net/?f=n%20%3D%20%5B%5Cfrac%7BZ_%7B%5Cfrac%7B%5Calpha%20%7D%7B2%7D%20%7D%7D%7BE%7D%20%5D%5E2%20%2A%20%5C%5E%20p%20%281%20-%20%5C%5E%20p%20%29%20) 
=>   ![n = [\frac{1.645 }{0.05} ]^2 * 0.5 (1 - 0.5 )](https://tex.z-dn.net/?f=n%20%3D%20%5B%5Cfrac%7B1.645%20%7D%7B0.05%7D%20%5D%5E2%20%2A%200.5%20%281%20-%200.5%20%29%20) 
=>
