Median,
={(n/2)th + (n/2 +1)th}/2
={(4)th + (5)th}/2
=(31.5)/2
=15.75
I.Q.R.,
Median of lower half,
={(n/2)th + (n/2 +1)th}/2
={(2)th + (3)th}/2
=(22.5)/2
= 11.25
Median of upper half,
={(n/2)th + (n/2 +1)th}/2
={(2)th + (3)th}/2
=35/2
=17.5
I.Q.R. = 17.5 - 11.25 = 6.25

Answer: 2 times
Step-by-step explanation:
Hi, since 1000 milliliters = 1 liter
We have to convert the 2 liters into milliliters:
2 x 1000 = 2000 milliliters, so she is using a 2,000 milliliters pincher.
Now we have to multiply the number of friends (10) by the amount of lemonade she serves to each one (400 ml)
400 x 10 = 4,000 milliliters
Finally, we have to divide the amount of lemonade she needs to serve (4,000 ml) by the capacity of the pitcher (2,000), to obtain the number of times that she will need to fill the pitcher.
4,000/2,000=2 times
Feel free to ask for more if needed or if you did not understand something.
Number 3: need more info
Number 4: is 337.5.
- first we need i\to find how much one case costs. $45/2 = $22.5
- next multiply $22.5 x 15 which gets you $337.50
Number 5: is 65%
- 100% divided by 3,100 is .03225806
- then multiply .023225806 by 1085 which gets you 35%
- but because it is asking for the remaining it is 100% - 35% which is 65%
The second and the third one because first is the same as 3 4/7 and 81=3^4
