50 dollars per month. It says "after x months" -50x is the variable thats changes. 
        
             
        
        
        
Using the binomial distribution, it is found that the mean and the standard deviation of variable x are given as follows:

<h3>What is the binomial probability distribution?</h3>
It is the probability of exactly <u>x successes on n repeated trials, with p probability</u> of a success on each trial.
The expected value of the binomial distribution is:
E(X) = np
The standard deviation of the binomial distribution is:

In this problem, we have that the parameters are given as follows:
n = 4, p = 0.75.
Hence the mean and the standard deviation are given as follows:
- E(X) = np = 4 x 0.75 = 3.

Answer:  or
   or  
   
Step-by-step explanation:
 Add the exponent two to both sides.  After adding -2 and     2 you get 0 and any number raised to the zero power is one. And 4 plus two is 6
   Add the exponent two to both sides.  After adding -2 and     2 you get 0 and any number raised to the zero power is one. And 4 plus two is 6

1/3x -11 = 4+x is what we start with, then add 11 to both sides, then subtract x from both sides. Then when we divide both sides by -2/3, x will equal -22.5.
        
             
        
        
        
None. If you think about it, 246 is greater than 6, so how can fit 246 into 6? Think about it this way . . how many times can you fit an elephant into a garden hose? . . yeah . . you probably can't . . try reposting your question . . and try making more sense of it next time. :)
