First, make 6 into an improper fraction.
6/1
Now multiply the numerators.
6x3=18
Now, the same with the denominators.
1x5=5
18/5
Now make it into a mixed number.
5x3=15
3 and...
18-15=3
3 and 3/5!!
Hope this helped!
        
             
        
        
        
Answer: x>6
Step-by-step explanation:
 
        
                    
             
        
        
        
It is B because for every point going down, there is 3 to the left and so it is 1/3 and it has to be negative because its going left
        
                    
             
        
        
        
If by factoring (n + 7) (n + 4)
        
             
        
        
        
Answer:
a. 4.05 b. 3.84 c. 1.2475 and 1.1344 d. 1.1169 and 1.0651  e. We can say that the overall job satistaction of senior executives and middle managers is about 4; however, there is more variability in the job satisfaction for senior executives than in the job satisfaction for middle managers.
Step-by-step explanation:
a. (1)(0.05)+(2)(0.09)+(3)(0.03)+(4)(0.42)+(5)(0.41) = 4.05
b. (1)(0.04)+(2)(0.1)+(3)(0.12)+(4)(0.46)+(5)(0.28) = 3.84
c. We compute the variances as follow: ![[(1)^2(0.05)+(2)^2(0.09)+(3)^2(0.03)+(4)^2(0.42)+(5)^2(0.41)] - 4.05^2](https://tex.z-dn.net/?f=%5B%281%29%5E2%280.05%29%2B%282%29%5E2%280.09%29%2B%283%29%5E2%280.03%29%2B%284%29%5E2%280.42%29%2B%285%29%5E2%280.41%29%5D%20-%204.05%5E2) = 1.2475 and
 = 1.2475 and ![[(1)^2(0.04)+(2)^2(0.1)+(3)^2(0.12)+(4)^2(0.46)+(5)^2(0.28)]-3.84^2](https://tex.z-dn.net/?f=%5B%281%29%5E2%280.04%29%2B%282%29%5E2%280.1%29%2B%283%29%5E2%280.12%29%2B%284%29%5E2%280.46%29%2B%285%29%5E2%280.28%29%5D-3.84%5E2) = 1.1344
 = 1.1344
d. The standard deviation is the squared root of the variance, therefore, we have  and
 and  
e. The expected value of the job satisfaction score for senior executives is very similar to the job satisfaction score for middle managers. We can say that the overall job satistaction of senior executives and middle managers is about 4; however, there is more variability in the job satisfaction for senior executives than in the job satisfaction for middle managers.
