Can anyone help me with this? NO LINKS PLEASE, giving brainliest.

Explanation:

Consider a full circle with diameter 15 inches

The circumference, aka distance around the circle's edge, would be...

C = pi*d

C = 3.14*15

C = 47.1

However, we want only half the curved distance as the diagram shows.

C/2 = (47.1)/2 = 23.55

The curved distance is roughly 23.55 inches.

Then we add on the two exterior sides of 15 inches each to complete the full perimeter of the shape: 23.55+15+15 = 53.55

Notes:

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.
