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
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
There are 90 different identification numbers possible.
<h3>What are the permutation and combination?</h3>
In terms of mathematical concepts, “permutation” and “combination” are related to each other.
The combination is the counting of selections that we make from n objects.
Oscar was not safeguarding his personal identification and chose a two-digit PIN for his debit card using the numbers 0 - 9.
There are 10 possible values for each digit of the PIN (namely: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9), so there are;
10 × 10 = 100 total possible PINs.
Now, because you can't use the same number twice, we subtract 10 from 100 because there are 10 numbers that can match themselves.
100 -10 =90
Hence, there are 90 different identification numbers possible.

Answer:
Your commission check for the 20% would be $160,000 and your 30% would be $240,000.
Step-by-step explanation:
To find each of these, multiply the total number of sales by the percentage of the commission.
$800,00*20% = $160,000
$800,000*30% = $240,000
