First step in finding the median is ordering the numbers 1. 4,10,12,14. Then you find out the number in the middle. step 1: 4,10,12,14 step 2: now, take out the first number so 10,12,14 Step 3: now take out the last number so 10,12 step 4: since there are two middle numbers, you average them. If you didn't know already, all you have to do to average them is add the two numbers together then divide them by two so 10+12=22 /2=11 now you want to find two numbers that if averaged with 11, make 8. so you could do two . final answer is 4,5,5,10,12,14
All the students can fit into the 60 second video and there will be 15 seconds left. 5 times 9 = 45. So, all of the students will equal a video of 45 seconds. To figure out the time left, you subtract, 60-45, which equals 15 extra seconds.
