You are painting a room and need the following supplies.
Supplies:

Paint: $15.89
Tarp: $9.49
Tape: $3.25
You have $40. Do you have enough money to buy your supplies? Use estimation to find out.

1. What is the estimated cost of the supplies

2. Do you have enough money?

3. What is the exact cost of
the supplies?

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.

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s
