Acompany is planning to make a new kind of radio. the cost to produce x radios is c(x) = 80,000 + 10x. meanwhile, the revenue earned by selling x radios is given by r(x) = 18x. if r < c, the company loses money. at what level of production does this happen?

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.

step-by-step explanation: 4 cause 2+2=4
