Which describes the slope of this line? a. positive slope b. negative slope c. zero slope d. undefined slope

The line is going down (from left to right), so it has a negative slope

horizontal lines have zero slope

vertical lines have undefined slope

lines going up (from left to right) would have positive slope

This is going down so it is Choice B

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.
