In 2003, Damian purchased a new car valued at $20,000. Four years later, the value of his car was $14,500. Assuming a constant rate of decrease,
how much did the value of Damian's car decrease per year?

$ 1,375

Step-by-step explanation:

20,000 - 14,500 = 5,500

5,500 ÷ 4 = 1,375

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
