Colin used 836.55 gallons of water over the course of 6 days. To the nearest hundredth of a gallon, how much water did Colin use, on average, each day?

139.43

Step-by-step explanation:

What I did was I divided 836.55 by 6 and came out to the 139.425. Since you mentioned we needed to round up to the nearest hundredth, I rounded up the .425 to .43

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.
