Answers

Answer 1
Answer: This is how you find the mean of a number:

To find the mean of a number, you need to add up all the numbers listed (so, 5, -11, 7, 12, -1 and 0) and then divide it by the amount of numbers there are listed. 5 + -11 + 7 + 12 + -1 + 0 equals 12, and since there are 6 numbers you then divide 12 by 6. 12 divided 6 is 2. 

So the answer is A. I hope this helped you!

In A School Election 3/4 Of The Students Vote. There Are 1464 Ballots. Write And Solve An Equation To Find The Number Of Students

Answers

A simple way to turn this into an equation is by replacing the words with letters: 
1464B = 3/4 S

Then you have to remove the 3/4 from the right side of the equation.  You can do this by dividing both sides by 3/4: 
1464 / 3/4 = S

Then you have to do the sum: 
   1464 
 / 3
= 0488

     488 
     X  4
= 1952

There are 1952 students.
