Which relation has a domain of {3,5,8}?
A. {(5, 1), (3, 4), (8, 2), (3, 3)}
B. {(3, 2), (5, 1), (8,3), (1,4)}
C. {(2,8), (1,3), (3,5)}
D. {(3,8), (5,3), (3,5)}

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.

dude thats to long figure it
