Solve this system of equations using a matrix inverse. x+y=10
2x-z=9
y-3z=-5

If A is the coefficient matrix of the above system of equations and A^(-1)=1/7[R1
R2
R3], then the elements of R1 are , the elements of R2 are , and the elements R3 are . The solution of this system is (x, y,z)=.

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.

understand that i don't know the answers

will someone answer his question

the real question is why is this guys last name heavyfoot
