Answer:
y= x/2-3
Step-by-step explanation:
 
        
             
        
        
        
You take the x and change it to the other side to leave y by itself and then divide by 2 = Y=-3-x
        
                    
             
        
        
        
Answer: b. Only statement (ii) is correct. 
Step-by-step explanation:
The given five-number summary of the ages of passengers on a cruise ship is listed below. 
Min 1     20     Median 29
 20     Median 29      38         Max 80
 38         Max 80 
Inter-quartile range = 
- According to the 1.5(IQR) criterion for outliers : An data value is an outlier if it lies below  or  above or  above . .
Here , 

Since the minimum value>  ( ∵ 1 > -7)
 ( ∵ 1 > -7) 
It means there is no value below  , so there is no low -outlier.
  , so there is no low -outlier.
⇒ Statement (i) "here is at least one passenger whose age is a low outlier. " is false.
But the maximum value >  (∵  85 > 65)
 (∵  85 > 65)
It means there are values above  .
.
⇒Statement (ii) "There is at least one passenger whose age is a high outlier" is true.
Hence, the correct answer is b. Only statement (ii) is correct.
