Ellinor made tables of values to solve a system of equations. first she found that the x-value of the solution was between 0 and 1, and then she found that it was between 0.5 and 1. next, she made this table.
a.(0.5,-1.8)
b.(0.9,-2.1)
c.(0.7,-1.5)
d.(0.6,-1.4)

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.

show us the graphs dude
