Take ln to both sides 
ln 14^x = ln 5
then you'll get 
x ln 14 = ln 5 
divide both sides by ln 14 
x = 0.6098533345
after rounding 
x = 0.6099
        
                    
             
        
        
        
Answer:
2.275%
Step-by-step explanation:
The first thing to do here is to calculate the z-score
Mathematically;
z-score = (x-mean)/SD
from the question, x = 12,300 hours , mean = 11,500 hours while Standard deviation(SD) = 400 hours
Plugging the values we have;
z-score = (12,300-11,500)/400 = 800/400 = 2
Now, we want to calculate P(z ≤ 2)
This is so because we are calculating within a particular value 
To calculate this, we use the z-score table.
Mathematically;
 P(z ≤ 2) = 1 - P(z > 2) = 1 - 0.97725 = 0.02275
To percentage = 2.275%
 
        
             
        
        
        
Answer:
B. 4t=27
Step-by-step explanation:
let t be the price of one ticket,
since there are 4 people buying tickets in total, the price of 4 tickets would be 4t.
