Answer:


Here Both the side of equation are same ..
So, it have infinite solution....
 
        
             
        
        
        
I guess no solution
4x +3 = 4X + 18
4X - 4X = 18 - 3
0 = 15

Answer:  The mean number of checks written per day  
Standard deviation
Variance  
Step-by-step explanation:
Given : The total number of checks wrote by person in a year = 126
Assume that the year is not a leap year.
Then  1 year = 365 days 
Let the random variable x represent the number of checks he wrote in one day.
Then , the mean number of checks wrote by person each days id=s given by :-

Since , the distribution is Poisson distribution , then the variance must equal to the mean value i.e. 
Standard deviation : 
 
        
             
        
        
        
A bakers dozen is 12 which would be $0.41 for each cookie. If you meant 13, it would be $0.38. All you have to do is divide 4.94 by the amount of cookies
