A person needs to rent a 12-foot moving truck for a day. He calls two rental companies to determine their fee structure. The first company charges $25 plus $0.40 per mile, and the second company charges $35 plus $0.30 per mile. After how many miles will the cost of renting the truck be the same? What is the cost at this mileage?

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.

yes. we do proportions in probabilities.
