W=5, X=3, Y=4, Z=8

X(to the second power) + 4W-2Y (divided by) Z

If you're looking for a number solution it's 28

Step-by-step explanation:

3^2+4(5)-2(4)/8

9+20-1

29-1

28

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.
