At the start of a trip, a car's gas tank contains 12 gallons of gasoline. during the trip, the car consumes
gallons of gasoline. how much gasoline is left in the tank?

Step-by-step explanation:

We are given the following information in the question:

Amount of gasoline in car's tank = 12 Gallons

Let be the amount of gasoline consumed by car during the trip.

Then, we can express the amount of gasoline left in car's tank with the help of an algebraic equation.

Thus,

Example:

if x = 4 that is amount of gasoline used during trip is 4 then amount of gasoline left in car tank is

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.
