A pool has 1,000 gallons of water in it, and a hose is filling the pool with 10 gallons per minute.
a) Write an equation for the total volume of water V in the pool after x minutes.
b) How many hours will it take to fill the pool to 10,000 gallons?

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.

step-by-step explanation:

the true ones are a b and d
