Hey there!
2.7 * 10^4 + 120
10^4
= 10 * 10 * 10 * 10
= 100 * 100
= 10,000
2.7 * 10,000 + 120
= 27,000 + 120
= 27,120
Therefore, your answer is. [10,000 * 2.712] because 10,000 * 2.712 is approximately 27,120
Good luck on your assignment and enjoy your day!

1) The population
Is the set of all the terms that the teacher taught this semester and which he wrote down on the note cards and put in the paper bag.
2) The sample is every set of five cards that is selected by each student.
3) I think the sample is representative because all ther terms have the same probability of being selected.
Further, given that the cards are replaced every time all the students will face the same population when they are going to select a sample.
