Select the correct answer. Create and solve a linear equation that represents the model, where circles and a square are shown evenly balanced on a balance beam. x + 7 = 5; x = -2 x = 5 + 7; x = 12 x + 5 = 7; x = 2 x + 7 = 12; x = 5

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.
