Answer:
New cars sold = 20,
Used cars sold = 25
Cars serviced = 290
Step-by-step explanation:
In a month they sold fifteen less used cars than twice the number of new cars.
Lets say 'x' number of new cars were sold, then:
The number of used car sold is:
In the same month they serviced fifty more than twelve times the number of new cars sold. So the number of cars serviced is:
Altogether they sold or serviced 335 cars, so the sum of all the cars sold and serviced should be 335:
Solving for 'x' we get:
Therefore, the number of new cars sold in that month is 20.
Number of used car sold
Number of cars serviced
We can also cross check by summing them up:
The domain of a relation is the set of all the x-terms of the relation.
Let's look at an example.
In the image provided I have attached a relation and we want to list the domain.
So, I will list all the x-terms. Notice however that I listed 7 once even though it appears twice in the relation. When listing the domain, you don't repeat the x-terms.

The Median refers to the middle of the set of number! So line up the numbers from largest to smallest or vice versa:
97,94,89,88,88,83
The middle number(s) is/are:
89 and 88.
Now we can use the same technique to find the mode, using the two number:
Now divide the sum by the number of numbers (2):
The Median is:
![\left[\begin{array}{ccc}88.5\end{array}\right]](https://tex.z-dn.net/?f=%20%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D88.5%5Cend%7Barray%7D%5Cright%5D%20)
Hope this helps!
