Physics (and math) are fun, really

Thank you so much for the answer! I have a question, if it were any other problem do I divide my amount of numbers or 6, and when I multiply each side I'm not sure which number to use

Nikita,
         To find the mean of a set of numbers you add the numbers and divide by the number of numbers. So in question 3 you divide by 6 again.
 
The median is 28 which is the middle of the set of ordered numbers. The ordered set is 21 24 x 30 30 32 the median is the average of the two middle numbers so (x+30)/2=28, so x+30=56, x=26. You should look up the definition of the median to be sure you know how to find it for odd and even sets of numbers.
  
Good luck on your quiz
