Help me find B asap!

11)

complimentary angle

b = 90 - 65

b = 25º

12)

supplementary angle

b = 180 - 117

b = 63º

13)

360º in a circle

b = 360 - 244 -23

b = 93º

14)

vertical angle

b = 46º

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.

50-38=12
