The length of a rectangle is 3 units more than the width. The area of the rectangle is 54 units. What is the width, in units, of the rectangle?

6

Step-by-step explanation:

Just a guess. But I worked out which numbers multiplied to make 54 and were 3 units apart. Which were 6 and 9

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.
