Given the equation 6(3 + 2x) = 54, which of the following equations are equivalent? 2) 18 + 12x = 54
3) 18 + 2x = 54 4) (3 + 2x)6 = 54
5) 54 = 18 + 12x 6) 3 + 6(2x) = 54

answer for this solution is 2,3,4.

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.
