A box is to be mailed. The volume of the box in cubic inches of the box can be expressed as the product of its three dimensions: v(x)=x^3 - 16x^2 +79x -120 The length is x –8. Find linear expressions for the other dimensions. Assume that the width is greater than the height.

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.
