With math. best gets brainliest.
celina is buying fabric scraps to make koozies for her glasses. each glass is cylindrical with a diameter of 3 inches and a height of 4 inches. the koozies will cover only the sides of the glasses. what is the amount of fabric she will use? what does this amount represent? use 3.14 for pi. show your work.

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.
