Y result from something being multiplied by X , and the values are always proportional to one another . Notice that putting these points into a ratio of x - value to Y - value result in 1:3 as a simplified version . So , The constant of proportionality is what x is being multiplied by to get y . In this case , it is 3
        
             
        
        
        
Answer:
The prevalence of serious defects in this population at the time of birth is 10%.
Step-by-step explanation:
The prevalence of serious defects is the number of infants that were born with seriours birth defects divided by the total number of infants born.
In this problem, we have that:
There were 1000 newborn infants.
100 infants were born with serious birth defects.
Calculate the prevalence of serious defects in this population at the time of birth.
This is:

The prevalence of serious defects in this population at the time of birth is 10%.
 
        
             
        
        
        
Answer:
y = -x + 2
Step-by-step explanation:
Lines that are parallel have the same slope but different 
y-intercepts.
So the slope of the parallel line is -x
We can input the x and y points given to solve for the new y-intercept
- y = -x + b
- 8 = -(-6) + b
- 8 = 6 + b
- b = 2
The new line is y = -x + 2. Since these two lines are the same, they are coinciding lines.

Answer:
16 lawns
Step-by-step explanation:
set up a proportion:
(4/5 ÷ 1) = (x÷20)
cross-multiply:
5x = 80
x = 16
