Your school is planning a field trip to the zoo. there are two different bus companies that the school can use. bus company a has a $25 rental fee of plus $4 for each student. bus company b has a $115 rental fee plus $2 for each student. how many students will need to go in order for the bus to cost the same from both companies? a) 42 students b)73 students c)70 students d)45 students

D. 45 students

25+4n=115+2n

     -2n         -2n

25+2n=115

-25         -25

2n=90

2n/2=90/2

n=45

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.

abde or 1,2,4, 5 is the answer
