What is the midpoint between each pair (-1, -5) and (-5, 9)

==============================================

Explanation:

The x coordinates are -1 and -5. They add to -6. Which is then cut in half to -3

The y coordinates are -5 and 9. They add to 4. This is cut in half to 2.

The midpoint is therefore (-3, 2)

-------

A symbolic way to write this is if you had endpoints (a,b) and (c,d), then the midpoint is

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.
