One diagonal of a rhombus is decreasing at a rate of 777 centimeters per minute and the other diagonal of the rhombus is increasing at a rate of 101010 centimeters per minute. At a certain instant, the decreasing diagonal is 444 centimeters and the increasing diagonal is 666 centimeters. What is the rate of change of the area of the rhombus at that instant (in square centimeters per minute)

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.
