GIVING BRAINLIEST PLEASE HELP!! -if you answer correctly ill give you brainliest which will give you 23pts-

d.     hope I get it right I never got brainliest

Step-by-step explanation:

Scale factor = 1 > A = 3.14 or pi unit²

Scale factor = 2 > A = 12.57 or 4pi unit²

Scale factor = 4 > A = 50.27 or 16pi unit²

Scale factor = 5 > A = 78.54 or 25pi unit²

Scale factor = 10 > A = 314.2 or 100pi unit²

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.
