Solve the system of equations 2r + 2s = 50 and 2r – s = 17. a. r = 3, s = 11 b. r = 25, s = 33 c. r = 14, s = 11 d. r = –8, s = 33

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:

where is the questions

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
