Answer:
C. 1/4
Step-by-step explanation:
Since John has given 2/3 of his pencils to Roy, he has 1/3 of the total left. To find 1/4 of 1/3, multiply the numbers. 1/4(1/3) = 1/12. This means that he gave 1/12 of the beginning total to Maria. 2/3 can also be written as 8/12, and 1 can be written as 12/12. 12/12 - 8/12 = 4/12, and then 4/12 - 1/12 = 3/12. 3/12 can be simplified into 1/4
One thousand seventy-five
Answer: 28.
Step-by-step explanation:
The median of a data set is defined as the middle value of a data set.
For instance, the median of the data set [4, 7, 8] would be 7 because it is the "middle value".
You can find this by sorting the numbers by smallest to largest:
2, 9, 15, 16, 21, 24, 28, 32, 34, 35, 37, 39, 40
There are 13 numbers in the set, so you can exclude the first 6 and last 6 numbers from the set to get your median, 28.
