Give me some info one what Jenny and Jeremy did and I can help you solve this :)
Is that one or two questions?
When you find any value to x amount of decimal places, you need to go to the term AFTER that to determine the correct value. So, for this, take 61.378 metres. From here, look if the last number is 4 or less. If the number is 4 or less, take the leftmost number off, and you will have your answer (if we had 61.373, the correct answer would be 61.37). If the number is 5 or more, take the leftmost number off, and add 1 to the new leftmost number. Since the last number is 8, the correct answer here is 61.38 metres high. If adding 1 makes the number 10, keep the 0 at the end. So, if you had 61.399, you would make it 61.40
The answer is 64. Hope it helps you
The samples he chose may not be a representative sample because the number of students per foreign language class may not be the same. One class may have a very large number of students while another may have only a few. Taking equal number of students per class is not a representative sample.<span />
