The measures of two sides of a triangle are (2 + 3) and (5 − 2). If the perimeter of the triangle is (12 + 5), what is the measure of the third side?

9

Step-by-step explanation:

First side: (2+3)=5

Second side: (5-2)=3

Perimeter: (12+5)=17

Take perimeter and minus the first and second side

17-5-3=9//

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.
