We have been given that a data set contains 10,000 values arranged in increasing order and we are asked to find where the median of this data will occur.
We know that the median of a data set with even number of entries is found by considering the average of the middle two values.
However, the median of a data set with odd number of entries can be found by considering the middle term of the sequence.
Since the number of entries in our data are 10,000, which happens to be an even number, therefore, we can find the median by computing the average of middle two values.
The middle two values of the data set with 10,000 entries are 5000th and 5001st numbers. Thus, the median of the data set will be average of 5000th and 5001st entries. Hope this helps!

Answer:
44%
Step-by-step explanation:
If p represents the number of portions and q represents the quantity in each portion, then the original amount needed was p·q.
After p is increased by 20%, its number is ...
p + 0.20·p = 1.20·p
After q is increased by 20%, its amount is ...
q + 0.20 ·q = 1.20·q
Then the new amount the parents must buy is ...
(1.20p)(1.20q) = 1.20²·pq = 1.44pq
This amount is ...
(1 + 44/100)·pq = pq + 44%·pq
It is 44% more than the original planned purchase.
Mr Jones typed 40 * 10 = 400 words.
Mrs Gonzales took 400 / 50 = 8 minutes to type same number of words.
2/3 is basically 0.6666666667 which is the same as 66% so any percentage bigger than 66% such as 75% (0.75) which is 3/4 (as a fraction) is bigger than 2/3
