Hannah sees an empty aquarium that can hold 25 gallons of water. There is a pump that can fill the aquarium with water at a constant rate. Hannah comes by later and sees the aquarium has 5 gallons of water. Two Minutes later the aquarium now has 8 gallons of water. A. At what rate is the amount of water in the aquarium changing?
B. How many more minutes will it take for the aquarium to fill completely?
C. How many more minutes before hannah arrived did it take the aquarium to fill up with 5 gallons of water?

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.

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
