Select the correct answer. Find the solution to the system of equations given below using elimination.
3.1 + 2y = -3
9x + 4y = 3
O
x = -6, y=-3
x = 3, y = -6
0
x = 3, y = 6
x = -6, y = 3

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.
