Solution :
Given :
X = the number of boys in a family of four children 
Families having four children are chosen randomly.
The gender distribution in the four child family are equally probable.
Thus, 
  X                P(X)                                          CDF
 0              = 1/16
        = 1/16                     
 1                = 1/4
       = 1/4                        
 
2                 = 3/8
      = 3/8                      
3                 = 1/4
      = 1/4                       
4                   = 1/16                      1
    = 1/16                      1
 
        
             
        
        
        
Answer:
12x2+2x6x34÷1613÷14
Step-by-step explanation:
 
        
             
        
        
        
Slope of the line;
slope=

Slope=

Slope,m =

y=mx+c
y=2x+c
Replacing for x and y using point (4,3)
3=2(4)+c
3=8+c
c=3-8
c=-5
y=2x-5
 
        
        
        
Answer:
Step-by-step explanation:
In the diagram shown, the measure of angle 1 is oppositely directed to angle 2 and oppositely directed angles are equal.
Hence <1 = <3
Given < 1 = 3x-1 and <3 = 2x+9
Hence 3x-1 =  2x+9
collect like terms
3x-2x = 9+1
x = 10°
Since <1 = 3x-1
on substituting x = 10
<1 = 3(10)-1
<1 = 30-1
<1 = 29°
<1+<2 = 180 (angle on a straight line)
29+<2 = 180
<2 = 180-29
<2 = 151°
Similarly, on substituting x = 10 into <3
<3 = 2x+9
<3 = 2(10)+9
<3 = 20+9
<3 = 29°
<3+<4 = 180 (angle on a straight line)
29+<4 = 180
<4 = 180-29
<4 = 151°
 
        
                    
             
        
        
        
Answer: 135*
Step-by-step explanation:
35* is what the bottom left side of the triangle angle equals because of congruency. 
All triangles = 180*
180 - 100 - 35 = 45*
top angle of triangle = 45 *
said angle (45) +  x angle = 180
x = 135*
