Pear Ridge apartments allows renters to get out of their lease early by paying a surcharge based on the number of months remaining on their lease, up to half of the original lease term. The surcharge is based on the function below. In this function, t is the number of months the lease term was signed for and m is the number of months remaining on the lease. Kendrick was transferred to a new facility at his job and will be moving out of state. If Kendrick has 3 months remaining on a 12-month lease, how much of a surcharge will he have to pay to break the lease?

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.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

true
