8. Which expression is equal to -9(6m - 3) + 6(1 + 4m) ? * 1 point
-30m + 33
-30m + 21
78m - 21
30m - 21
Answer quick

- 30m + 33

Step-by-step explanation:

Distribute

-54m + 27 + 6 +24m

combine like terms

-30m + 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.
