Wright a simple equation :)

6 pairs of socks

Step-by-step explanation:

I started with $15.99 and subtracted that by $21.93. $21.93-$15.99= $5.94. Then I divided $5.94 by $0.99. $5.94/$0.99= 6. I hope this helped

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.

y=mx+b is the final answer!   : )
