X = -4
the slope is undefined as it only passes through the x-axis on -4.
        
             
        
        
        
Answer:
0.224
Step-by-step explanation:
2/5% = 0.004
22% = 0.22
22% + 2/5% = 0.224
 
        
                    
             
        
        
        
Answer:
a. 0.7291
b. 0.9968
c. 0.7259
Step-by-step explanation:
a. np and n(1-p) can be calculated as:

#Both np and np(1-p) are greater than 5, hence, normal approximation is most appropriate:

#Define Y:
Y~(11.04,5.7408)

Hence, the probability of 12 or fewer is 0.8291
b. The  probability that 5 or more fish were caught.
#Using normal approximation:

Hence, the probability of catching 5+ is 0.9968
c. The probability of between 5 and 12 is calculated as;
-From b above  and a ,
 and a , =0.7291
=0.7291

Hence, the probability of between 5 and 12 is 0.7259
