Which of the following sets of ordered pairs in the form (x, y) represent a function of x? 3 points {(2,4), (-2,4), (5,3), (7,4)} {(3,,,2), (-6,2)} {(9,2), (-3,4), (-3,1), (7,-4)} {(5,,-,-4), (6,1) show work

the answer should be ai hope this

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.
