Someone explain this step by step to me 1/2(c-8)=

c/2-4

Step-by-step explanation:

This is what I get :

1/2(c-8)

Distributed property

1/2(c) + 1/2(-8)

Do c and -8 as a fraction with denominator 1 solve across

1/2×c/1+1/2×-8/1

Here you can only divide -8by 2

C/2-8/2

To get -4

C/2-4

You can't go further

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.

ian gonna lie that is way to much
