1/3x-2y=7 is linear or nonlinear

I hope this helps

Step-by-step explanation: It is linear

Basically just turn it into slope intercept form which is y=mx+b and if it doesn't have an exponent it is linear.

and also remember it is in standard form in the question which is Ax+By =C

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.

it has the same slope and a different y-intercept

hope this : )
