What is 2/5 y + 1/5 x -0.2y-6+(-2)

Step-by-step explanation:

1)  Simplify 2 /5y to 2y/5.

2) simplify 1/5x to x/5.

3) Collect like terms.

4) Simplify.

Therefor, the answer is y/5 + x/5 -8.

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.
