Answer:
Probability of getting at least one 2 equals 0.5177
Step-by-step explanation:
The probability of at least one success is

where, 
'p' is probability of success of 1 trail
'n' is number of events
We have probability of getting 2 is 1/6 thus 'p' = 1/6
Applying values we get

 
        
             
        
        
        
Hello!
Since we are given that the speed of sound in the air travels about 343 meters per second, we can multiply 343 meters per second by 5, and then we convert the meters to kilometers.
343 · 5 = 1715 meters per 5 seconds.
1000 meters are equal to 1 kilometer. So, we can divide 1715 by 1000 to convert meters to kilometers.
1715 / 1000 = 1.715
Therefore, the speed of sound in air is about 1.715 kilometers per 5 seconds. 
 
        
                    
             
        
        
        
It's not a function because the x value repeated but wasn't accompanied by the same y value . there is (-2,2) and (-2,14) but if they had the same y value like (-2,2) and (-2,2) or (-2,14) and (-2,14) the table would represent a function. If you still dont understand I'll be more than happy to elaborate :)

Use the Pythagorean Theorem to find the length of the line segment connecting (4,-6) and (9,-5).  The change in x is 5 and the change in y is 1.  Thus, the 
hypotenuse is     sqrt(5^2 + 1^2) = sqrt(26) (answer).
