Put the numbers in order: 9, 14, 16, 18, 20, 24, 26, 27, 28 There are n numbers so the median (the middle one) is the one in position (9+1)/2 ie the 5th. Thus, median = 20.
14. Put in order: {1, 6, 10, 12, 12, 13, 15, 19, 27, 31, 32, 40} There are 12 data items, so the median is the (12 + 1) ÷ 2 = 61/2th data item. As 61/2 is not a whole number, take the mean average of the 6th and 7th data items: 6th is 13, 7th is 15 ⇒ median = (13 + 15) ÷ 2 = 14
(10, 12, 13, 17, 17, 18, 27) The median is 17. The mode is 17. The range is 17.
15.5
When put in order, the numbers are: 16, 18, 24, 25, 26, 27, 31, 32 and 2123. The median is the middle number, which is 26. If you mean the 2123 to be 21 and 23, then the numbers are: 16, 18, 21, 23, 24, 25, 26, 27, 31 and 32. In this case, there is an even amount of numbers, so the median is the value halfway between the two middle numbers. They are 24 and 25, so the median is 24.5 as your answer.
Put the numbers in order: 9, 14, 16, 18, 20, 24, 26, 27, 28 There are n numbers so the median (the middle one) is the one in position (9+1)/2 ie the 5th. Thus, median = 20.
There are six numbers, so the median is the mean of the third and fourth (when ordered). Median = (14+27)/2 = 41/2 = 20.5
32 apex
The median of the numbers 10 12 13 17 17 18 27 is 17.
E 13 the order is :7 ,12 ,14 ,16 ,21 ,24 ,25 ,27 .
14. Put in order: {1, 6, 10, 12, 12, 13, 15, 19, 27, 31, 32, 40} There are 12 data items, so the median is the (12 + 1) ÷ 2 = 61/2th data item. As 61/2 is not a whole number, take the mean average of the 6th and 7th data items: 6th is 13, 7th is 15 ⇒ median = (13 + 15) ÷ 2 = 14
17. It's the middle number when they are put into order.
(10, 12, 13, 17, 17, 18, 27) The median is 17. The mode is 17. The range is 17.
18 is the median of these numbers.
15.5
When put in order, the numbers are: 16, 18, 24, 25, 26, 27, 31, 32 and 2123. The median is the middle number, which is 26. If you mean the 2123 to be 21 and 23, then the numbers are: 16, 18, 21, 23, 24, 25, 26, 27, 31 and 32. In this case, there is an even amount of numbers, so the median is the value halfway between the two middle numbers. They are 24 and 25, so the median is 24.5 as your answer.
Multiplying fractions is about as easy as it could be.-- The numerator of the product is the product of the two numerators.-- The denominator of the product is the product of the two denominators.(18/16) x (12/14) = (18 x 12)/(16 x 14) = 216/224If you'd like to simplify that answer, it's 27/28 .
