A woman drives an SUV that gets 15 mi/gal (mpg). Her husband drives a hybrid that gets 50 mpg. Every week, they travel the same number of miles. They want to improve their combined mpg. They have two options on how they can improve it.

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.

trapezoid

step-by-step explanation:
