The number is 6 bc have of 12 is six
4 is in the hundredths place
Mean is an average.
In order to find mean we must add up all the numbers and divide by how many numbers there are.
82 + 105 + 247 + 119 + 94 + 202
Adding them together and we get...
849.
We can see that we have 6 numbers.
849/6
849 divided by 6 is...
141.5
That is the mean.

Answer:
80 Students were surveyed.
Step-by-step explanation:
To find the answer we need to do a Rule of Three. The Rule of Three is a Mathematical Rule that will help us to solve problems based on proportions.
1. I know that a 65% of students are 52 students. I need to know how many students represent that 100%.
2. So if 52 students mean _____ 65%
X students mean _____ 100%
Pay attention here. We have to put the same elements in the same columns. Students with studients and percentage with percentage.
3. Now I have to cross these details. I have to multiple 52*100. So:
52*100= 5200
4. Then divide that result by 65.
5200/65= 80
5. So 80 is the total number of students surveyed.
