A5.20 bucket of water is accelerated upward by a cord of negligible mass whose breaking strength is 70.0. if the bucket starts from rest, what is the minimum time required to raise the bucket a vertical distance of 12.5 without breaking the cord?

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.

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.
