Answer:
7^15
Step-by-step explanation:
7^5^3 = 7^(5*3) = 7^15
 
        
             
        
        
        
<em><u>The average would be 16.</u></em>
To calculate this, add all the values together then divide that sum by the amount of data values.
11+16+15+22=64
64÷4=16
 
        
             
        
        
        
To solve this, just take $80 and subtract her amount of money she has now, which is 8. $80-$8=$72
She needs $72
        
                    
             
        
        
        
The limit of a function f at a point a exists if:


Also,

 
Therefore, 

Hence, the limit does not exist
