The answer is B
We already know the rate of change for function A, 2, to find the rate of change for function B you have to divide the change in Y by the change in X, which gives you 4.
        
                    
             
        
        
        
Answer:


Step-by-step explanation:
The given parameters can be represented as:

Solving (a): P(x < 3)
This is calculated as:
 ----- i.e. all probabilities less than 3
 ----- i.e. all probabilities less than 3
So, we have:


Solving (b): Expected number of events
This is calculated as:

So, we have:

If you meant -3x then the answer is (2,12)
        
             
        
        
        
Parallel - same slope so the line with parallel to it has a slope of 6
Perpendicular - opposite negative reciprocal so the perpendicular line should have a slope of 6 too or -6.
        
             
        
        
        
Answer:
1) Slope of the line  
2)Slope of the line m = 2
3) slope of the line m = -5
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that equation of the straight line 3 x+2 y =0
The slope - intercept form    y = mx +c
                                               2 y = - 3x
                                                
 
 Slope of the line  
<u><em>Step(ii):-</em></u>
Given that equation of the straight line 2 x- y = 3
The slope - intercept form    y = mx +c
                                               y = 2x -3
slope of the line m = 2
<u><em>Step(iii):-</em></u>
Given that equation of the straight line 5 x + y = 10
The slope - intercept form    y = mx +c 
                                               y = -5x +10
slope of the line m = -5
