Step-by-step explanation:
there is no mathematical problem to solve. 
just follow the instructions as given. 
this is an exercise for you to get a feeling about what is what. it is imperative that you do it. 
there is really nothing to solve.
remember, that a positive slope means the line goes up (from left to right), and a negative slope means the line goes down (again from left to right).
and I am sure you know what vertical and horizontal means.
 
        
             
        
        
        
Answer:  P(A and B) is greater than P(A)
P(A and B) should be smaller than P(A).
 
Step-by-step explanation:
Given :  P(A and B) = 0.40 
P(A) = 0.20
Using the given formula of the conditional probability will be 

But we know that the probability of any event cannot be more than 1.
Also, the probability of the intersection must be less than the probability of individual event.
Thus , in the given question P(A and B) must be smaller than P(A).
 
 
        
             
        
        
        
Answer:
 The perimeter of the dog's play area is 30 ft
Step-by-step explanation:
Rectangle:
- The opposite sides are congruent.
- The opposite angles are congruent.
- The sum of all four angles of a rectangle is 360°.
- The sum of two adjacent angles of a rectangle is 180°.
- The diagonals bisect each other.
- The perimeter of a rectangle is = 2(Length+width)
- The area of a rectangle is = Length × width 
Given that,
The length of the long side of the dog's play area was = 10 ft.
So, Length of dog's play area is = 10 ft.
The length of the short side of the dog's play area was = 5 ft.
So, width of dog's play area is = 5 ft.
It is a rectangular plot.
So, the perimeter of the dog's play area is =2(Length+width)
                                                                       =2(10+5) ft
                                                                       =2(15) ft
                                                                       =30 ft
