2. prove the part of the theorem which lets w be any solution of ax=b, and defines vn =w-p. show that vn is a solution of ax = 0. this shows that every solution of ax = b has the form w=p+vn, with p a particular solution of ax=b and vh a solution of ax = 0. let w and p be solutions of ax = b. substitute for vn from the equation w=p+vh av=ac what theorem should be used next? o a. ax = xya1 + xza2 + + x, an ob. u +v=v+u c. aſcu) = c(au) od. a(u + v) = au +av use that theorem to change the right side of the equation found above. av. simplify the right side of the equation that was just found. avna so avna thus, vn is a solution of ax = 0.

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.

x=6 and x=3
