Answer:
Step-by-step explanation:
What is the question? If you want to know how to graph this equation, it's usually easiest to start with the intercepts, i.e., the points where the line crosses the axes.
y  = ½x + 3 tells you that the line crosses the y-axis at (0,3), so plot that point.
Then let y = 0 and solve for x.
0 = ½x + 3
x = 6
The line crosses the x-axis at (6,0), so plot that point as well.
Then draw the line passing through those two points.
 
        
             
        
        
        
Answer:number of children negative for chicken pox=28
Step-by-step explanation:
Number of  children positive for chicken pox =18 out of 30
Therefore number  of children negative for chicken pox is 12 out of 30 ie ( 30-18)
 Such that the ratio of positive tested chicken pox children to negative tested chicken pox children =18:12
Therefore  total ratio =18 +12=30
Suppose there are 70 children,then number of children negative for chicken pox =
12/30 x 70  =28

Answer:
V = 16 pi h
Step-by-step explanation:
If the diameter is 8, the radius is d/2 =4
The volume is given by
V = pi r^2h
V = pi (4^2)h
V = 16 pi h
