Work out the median 8, 6, 4, 5, 9,8

7

Step-by-step explanation:

the median is the middle and if you order them

4,5,6,8,8,9 then you remove one from each side until you have 6,8 so you go in-between the two (seven)

7

Step-by-step explanation:

You need to arrange the numbers in an increasing order:

4 5 6 8 8 9

then you need to count how many values we have in the specific set:

6 total values

now we need to find the middle of our set

4 5 6 II 8 8 9

and then we divide the two numbers next to the middle part (6;8) and divide them by 2

(6+8):2=7

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
