Ashley is the utility manager at a paper mill. She’s watching over one of her holding tanks. It takes 4/5 of an hour to fill 1/2 the tank. At this rate how many holding tanks will she fill in an hour

she will fill 5/8 of the tank in 1 hour

Ashley is the utilities manager at a paper mill. She’s watching over one of her holding tanks. It takes 4/5 of an hour to fill 1/2 the tank

First we convert 4/5 of an hour in to minutes

4/5 * 60 = 48 minutes

In 48 minutes > 1/2 tank filled

In 60 minutes > 60 * 1/2 divide by 48

30 divide by 48= 30/48

Simplify the fraction by dividing top and bottom by 6

30/48 = 5/8

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.
