we are given 

Here, 
y is the number of gallons of water in the pool
x is the number of minutes the truck has been filing the pool
now, we will verify each options 
option-A:
When x=1 
then y=19.75 
so, for 1 minute , number gallons =19.75
so, this is FALSE
option-B:
Since, we have 

It is similar to equation of line 
y=mx+b
But b=0
It means that it passes through origin
so, this is TRUE
option-C:

we can compare it with 
y=mx
where m is the rate 
so, we get 

while we are given 
the water in swimming pool increase about 100 gallons by every 5 minutes
so, we get rate as
 gallons per minute
 gallons per minute 
this is close to 19.75 
so, they are approximately equal
so, this is TRUE
option-d:
x-value and y-value will show relationship
and ratio will always be constant or equivalent
because it has linear relationship
so, this is TRUE
option-e:
We need to check 
(8,150) ..so, x=8 and y=150
we can plug this in our equation 
and we get 


Since, left side is not equal to right side 
so, this can not be point 
so, this is FALSE
 
        
             
        
        
        
Answer:
Parameter
Step-by-step explanation:
Required
Parameter of Statistic
From the question, we understand that the teacher is to calculate the class average.
To calculate the class average, the teacher will use the mean function/formula, which is calculated as:

Generally, mean is an example of a parameter.
<em>So, we can conclude that the teacher will use parameer</em>

Answer:
$43.65
Step-by-step explanation:
1. divide 48.50 by 10
4.85
2. subtract 4.85 from 48.50
3. your answer would be $43.65
 
        
                    
             
        
        
        
A. 1 pound of cherries costs 2.50
B. Yes it is constant
C. I believe that you would put cost on the y and lbs on the x
E. 5 lbs of cherries = 2.50 x 5 = $12.50
