in the figure below, angle dec is congruent to angle dce, angle b is congruent to angle f, and line df is congruent to line bd. point c is the point of intersection between line and ag and line bd while point e is the point of intersection between line ag and line df.

prove triangle abc is congruent to triangle gfe.

i need a two-column proof.

i have no idea where to start!

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.

answer: check all that apply, where the options?
