It is (-15 + 20)/2 = 5/2 = 2.5
11 13 15 18 20 20 The median is the middle number when they are in numerical order, so the median is 16.5. It is 16.5 because there is an even number of integers so you find the middle of 15 and 18
15
17.5 It is 2.5 more than 15 and 2.5 less than 20 To find a halfway point (which is also the average), add the numbers together and divide by 2.
(10+20)/2 = 30/2 = 15
'15' Hence 3 x 5 = 15 or 15/3 = 5 or 15/5 = 3
11 13 15 18 20 20 The median is the middle number when they are in numerical order, so the median is 16.5. It is 16.5 because there is an even number of integers so you find the middle of 15 and 18
The middle number between 20 and 25 is calculated by finding the average of the two numbers. This is done by adding them together (20 + 25 = 45) and then dividing by 2, resulting in 22.5. Therefore, the middle number is 22.5.
15
the answer is 15
The number 20 is.
The number halfway between 15 and 25 can be found by taking the average of the two numbers. To calculate this, add 15 and 25 together to get 40, then divide by 2 to get 20. Therefore, the number halfway between 15 and 25 is 20.
17.5 It is 2.5 more than 15 and 2.5 less than 20 To find a halfway point (which is also the average), add the numbers together and divide by 2.
It is 20, the number in the middle when they are arranged in order.
17... and 19 !
To find the number that is in the exact middle of two numbers, add the numbers and divide by 2.25 + 15 = 40. 40 divided by 2 = 20.26.9 is one of infinitely many values between 27 and 15.
the middle is 15
The mode is the number which occurs most - so this is 20 The median is the middle number if you write them all in numerical order..... 5, 13, 13, 15, 18, 20, 20, 20 The answer is 16.5 which is in the middle of 15 and 18 To find the mean you add all the numbers up 5+13+13+15+18+20+20+20=124 then divide by the number of numbers in the range (8). 124/8 = 15.5
