Answer:
The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
The median is also the number that is halfway into the set. To find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.
The range of a set of data is the difference between the highest and lowest values in the set. To find the range, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.

Answer:
The number of new vehicles is 196
Step-by-step explanation:
Let
x ----> the number of new vehicles
y ----> the number of used vehicles
we know that
Currently, they have 280 vehicles
so
----> equation A
The ratio of new to used vehicles is 7:3
so

substitute equation B in equation A
solve for y
Find the value of x
therefore
The number of new vehicles is 196
