Hi there! Hopefully this helps!

Question A answer: 2. 
To find the <u>median</u>, you simply need to order the set from lowest to highest and finding the <u><em>exact middle</em></u>. So it should look like this:
0, 1, <em><u>2</u></em>, 3, 4. So 2 is the median, therefore 2 is the answer to Question A.
------------------------------------------------------------------------------------------------
Question B answer: 2
To find the <u>mean</u>, you have to add all of the numbers together and then you have to <u>divide by the number of items in the set</u>. There are 5 numbers in the set so it should look like this:
0 + 1 + 2 + 3 + 4 = 10.  
Since there 5 numbers in the set, we need to divide by 5.
10 / 5 = 2.
Therefore, 2 is also the answer to Question B.

Tim spends 500 minutes at the school.
Step-by-step explanation:
Given, 
Time for lunch = 45 minutes 
Time for study hall = 45 minutes 
Total = 45+45 = 90 minutes 
This represents 18% of the total minutes Tim spend at school.
Let, 
x be the total minutes Tim spend at school. 
18% of x = 90 minutes 

Dividing both sides by 0.18

Tim spends 500 minutes at the school.
