Answer:
0.0903
Step-by-step explanation:
Given that :
 The mean = 1450
The standard deviation = 220
sample mean = 1560



P(X> 1560) = P(Z > 0.5)
P(X> 1560) = 1 - P(Z < 0.5)
From the z tables;
P(X> 1560) = 1 - 0.6915
P(X> 1560) = 0.3085
Let consider the given number of weeks = 52
Mean  = np = 52 × 0.3085 = 16.042
 = np = 52 × 0.3085 = 16.042
The standard deviation =   
 
The standard deviation = 
The standard deviation = 3.3306
Let Y be a random variable that proceeds in a binomial distribution, which denotes the number of weeks in a year that exceeds $1560.
Then;
Pr ( Y > 20) = P( z > 20)


From z tables
P(Y > 20)  0.0903
 0.0903
 
        
             
        
        
        
GCF means the term(s) that 6x and x have. 
The GCF is x because:
1. Using multiplication: 6x * x = 6x^2 
becomes x(6+x) = 6x^2 
GCF is x. 
Good luck to you!
        
             
        
        
        
Answer:
X=1 9/10
Step-by-step explanation:
6X multiply 2 - 2X=19
Calculate the product
12X-2X=19
Collect the like terms
10X=19
Divide both sides of the equation by 10
X=19/10
Simplify the improper fraction
X=1 9/10
