What is the area of the sector bound by the center of the circle and arc CD in the circle below?

Circle A is shown with a radius labeled 6 feet and a central angle marked 30 degrees.

a
9.42 ft2

b
19.54 ft2

c
34.89 ft2

d
88.31 ft2

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.
