Answer:
Choice A
Step-by-step explanation:
5 red socks, 2 white socks, 3 blue socks = 10 socks
1 st sock red : 5 / 10
2nd sock red : 4/9
we didn't put the sock back
a pair of red socks
5/10 * 4/9 = 20/90 = 2/9
 
        
             
        
        
        
Answer:
 <em>k = - 7.5 </em>
Step-by-step explanation:
Slope "m" of a line through points 
(  ,
 ,  )
 ) 
(  ,
 ,  )
 ) 
is m =  
 
Slopes of perpendicular lines are opposite reciprocal:  
  = - 1
 = - 1 
~~~~~~~~~~~~~~~ 
The slope of a line through points (0, 7) and (2, 10) 
 =
 =  =
 =  
 
Slope of perpendicular line through points (3, 5) and (k, 12) is  =
 =  
 
or  =
 =  
 
 =
 =  
 
2(k - 3) = - 21 
k - 3 = - 10.5 
<em>k = - 7.5</em> 
 
        
             
        
        
        
I think you forgot to put in the image
        
             
        
        
        
Both the red and white roses would make up seven roses
        
             
        
        
        
4/8 = 1/2 so it is four eigths in one half.  4/8 simplified is 1/2
