Answer:
a
  
b
  
Step-by-step explanation:
From the question we are told that 
    The sample size is  n =  103  
     The  sample mean of  sag is  
      The sample mean of swells is  
     The standard deviation of  sag is  
      The standard deviation of swells is  
      The number of swell for a randomly selected transformer is  k  =  100
       The number of sag for a randomly selected transformer is  c  =  400
Generally the z-score for the number of swells is mathematically represented as
      
=>   
=>     
        
Generally the z-score for the number of sags is mathematically represented as     
       
      
      
 
        
             
        
        
        
Answer:
Equation
 is in the standard dorm.
Step-by-step explanation:
Here, the x - intercept = 4 , so ( 4,0) is a point on the line.
and the y - intercept = 5, so ( 0,5) is a point on the line.
So, the slope of the equation is given as  =  
Now, the SLOPE INTERCEPT FORM of an equation is :
y  = mx + b: here m  = slope and b =  y- intercept
or, 
Now, standard form is Ax +By = C
So, the standard form is 
Hence, the above equation 
 is in the standard dorm.

Answer:

Step-by-step explanation:
We have the following solution:

We want to find the value of x that satisfies the following condition:
y(3) = 3.
This means that when x = 3, y = 3. So
