Solve the equation using mental math n divide 9=9

81

Step-by-step explanation:

When dividing these numbers, you would actually multiply them together because they are on different sides of the equals sign. You do this because whatever you do on one side, you'd do the opposite of to the other side.

Example:

2x + 3 = 9

You would subtract 3 from nine.

2x = 6

The you'd divide 6 by two, since you would multiply x by two.

x = 3

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.
