Answer: C. 30.47
Step-by-step explanation:
The mean of discrete random variable i.e. the expected value of X is given by :-

Now by using the given table, the expected value of X is given by :-

Hence, the  mean of discrete random variable= 30.47
 
        
             
        
        
        
Answer:
Part a) We should try to eliminate the y's because the coefficients are the same
Part b) The solution is the point (6,-9)
Step-by-step explanation:
Part a) Which variable pair should we try to eliminate?
we have
 ----> equation 1
 ----> equation 1
 ----> equation 2
 ----> equation 2
Solve by elimination
We should try to eliminate the y's because the coefficients are the same
Part b) What is the solution to the system?
Multiply equation 2 by -1 both sides

 -----> equation 3
 -----> equation 3
Adds equation 1 and equation 3

Find the value of y

The solution is the point (6,-9)
 
        
             
        
        
        
Answer:
There is no answer to this question.
Step-by-step explanation:
First of all the variable  is not in the equation.
 is not in the equation.
Second of all, y=mx+b has only variables, it can only be simplified to
