Answer:
 
And we can find this probability using the complement rule and the normal standard table:
 
And the best solution would be:
c. 0.3085
Step-by-step explanation:
For this case we can convert all the values to inches in order to standardize the solution:


Let X the random variable that represent the heights of US mens, and for this case we know the distribution for X is given by:
 
  
Where  and
 and  
We are interested on this probability
 
We can use the z score formula given by:
 
Using this formula we got:
 
And we can find this probability using the complement rule and the normal standard table:
 
And the best solution would be:
c. 0.3085
 
        
             
        
        
        
Well

 translates to 

so
log5(x/2)=5 means 5^5=x/2, so 3125=x/2, so 6250=x
 
        
        
        
Answer:
Step-by-step explanation:
Linear means strait but what are you asking ? 
 
        
             
        
        
        
There are 5 vowels. 
There are 26 letters in total. 
Then, the probability of choosing a vowel is 5/26
