The equation V(t) = 12,000(0.75)' represents the value of a motorcycle tyears after it was purchased. Which statement is true? А
The motorcycle cost $9000 when purchased
B
The motorcycle cost $12,000 when purchased.
с.
The motorcycle's value is decreasing at a rate of 75% each year.
D
The motorcycle's value is decreasing at a rate of 0.25% each year.

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.
