The advertising and sales model of a company is given by the function s = 2t2 + 100, where t is time in months and t ≥ 0. if advertising is delayed by a month, which type of transformation will occur to this model?

a.
shift along the x–axis

b.
shift along the y–axis

c.
reflection through the y–axis

d.
reflection through the origin

answer: it is a.   shift along the x–axis

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.

true
