Which ordered pair is a solution of the system 3x+y=-3 and y=x+5? a: (3,-2)
b: (-4/3, 1)
c: (-2, 3)
d: (-8/3, -3)

The correct answer is C. (-2,3)

Step-by-step explanation:

Hope this helps :)

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.
