A rectangular pool has a width of 24 feet. A second rectangular pool has a perimeter of 48 feet, which is __1
3
the perimeter of the first pool

Let x = the length

Let P = the perimeter of the first pool

48 = (1/3)P

144 feet = P

P = 2l + 2w

144 = 2x + 2(24)

144 = 2x + 48

96 = 2x

48 feet = x

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.
