Mindy, luis, felix, and reiko take lessons in guitar, dance, karate, and skating. Each takes a different bus to the lesson- 283, 342, 475, or 528. Mindy rides the bus whose digits add up to 16, and riko takes a bus whose number is divisible by 8. Bus 283 goes to the karate studio. Felix does not study dance or karate. Reiko like music only when she’s on the ice. Which bus does each person take to the what lesson?

answer: 32.68

step-by-step explanation:

x=2

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:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
