Mr. sheng is using a faucet attachment to fill the fish tank in his biology classroom. the graph below shows the amount of water in the tank during the first several minutes since he turned on the faucet. what is the slope of a line joining the points on the graph? if your answer is not an integer, express it as a decimal.

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.

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.
