Answer:
30 km
Step-by-step explanation:
1 kilometer = 100 meters.
1 meter = 100 cm
therefore, 1 km = 10,000
and then, 300000 cm is 30 km
 
        
             
        
        
        
Answer:
Z=2.36
P=0.0091
Step-by-step explanation:
The hypothesis is:
π > 0.55 which is the population proportion 
The formula to get the test statistic is 
Zstat = P-π/√π(1-π)/n
P =507.4/860 = 0.59 (sample proportion )
n =860 (sample size)
π =0.55(population porportion)
Zstat = 0.59-0.55/√0.55(1-0.55)/860 
Zstat =2.36
From Z table the probability of Z score of 2.36 is 0.9909
To calculate for P- value will then be 
P= 1 - 0.9909
P= 0.0091
 
        
             
        
        
        
Answer:


Step-by-step explanation:
 
        
             
        
        
        
5 + 2 = 7
1/4 + 3/4 = 1
7 + 1 = 8
Your answer is 8
        
                    
             
        
        
        
If you multiply 0.83% by 2192.4 you will roughly about 18.26
