The answer if F

x =2

Perimeter = 54

Step-by-step explanation:

You can cut the polygon into different shapes. The one with a missing side is a  rectangle. Cutting it results in sides 3, 8, 6 + ?, and 3. All opposite sides are equal. x =2. The perimeter, you add the sides. 3 + 6 + 3 + 2 + 6 +4 + 15 +4 +3 + 8 = 9 + 5 + 10 + 19 + 11 = 14 + 29 + 11 = 14 + 40 = 54

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.
