Which expression is equivalent to 4 (x + 3) ? A. 4x + 3x
B. 4 + x + 3
C. 4x + 12
D. 4x + 3

C.

Step-by-step explanation:

distribute the 4 to the quantity (x+3)

we get: 4x + 12 so your answer is C.

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.
