Find the value of x i really need the answer to this asap

since they are across from each other they would have equal value,

so

(5x + 15) = (6x - 10)

-5x -5x

15 = x - 10

+10 +10

25 = x

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.

i just took the test, the correct answer is .. 31.5 in.
