Answer:
x ≈ 1.4
Step-by-step explanation:
Using the sine ratio in the right triangle
sin50° =  =
 =  =
 =  ( multiply both sides by 1.8 )
 ( multiply both sides by 1.8 )
1.8 × sin50° = x , then
x ≈ 1.4 ( to the nearest tenth )
 
        
             
        
        
        
Answer:
8
Step-by-step explanation:  
x=average
(x+x+x+x)/4=average
to increase x by 2 you add 2
x+2=average
(x+2+x+2+x+2+x+2)=4=(4x+8)/4=x+2
you'd have to increase the sum by 8 to make the numbers' averages' go up by 2
 
        
             
        
        
        
Answer: Option (B) is correct.
Step-by-step explanation:
The number of points scored during a basketball game is a discrete random variable.
Discrete Random variable:
A discrete random variable is a variable whose value can be evaluated by counting. It is also referred as a countable and finite values. Examples of discrete random variable are as follows:
-The quantity of runs scored during a ball game  
- Number of hits a site gets during seven days  
- Number of lights that wear out in the following year in a stay with 13 bulbs  
- Number of pigeons in a city  
- Number of free-toss endeavors before the principal shot is missed
 
        
                    
             
        
        
        
Answer:
C(-4,-2), D(3,-7)

Step-by-step explanation:
we procced to identify points:
A(-4,-7), B(3,-2)
for being the sides of a rectangle parallel to the axes, we find the other two vertices (VIEW GRAPH) 
C(-4,-2), D(3,-7);  Area of the rectangle Ar=b*h, where

So Ar=(3-(-4))*(-2-(-7)) = (3+4)*(-2+7)=7*5=
