The median of a set of numbers is the middle number when the numbers are listed in numerical order. When there are an even number of data items in the set, then the median is the mean average of the middle two numbers. In the set {16, 25} there are two data items, so the median is the mean average of the middle two (which for a set of 2 is both the numbers) → median = (16 + 25) ÷ 2 = 20.5
The greatest common factor of the numbers 25 and 24 is 1.
There are an infinite amount of answers to that. 22, 23, 24, 25 and 26 would be one set of answers.
The average is 24.
The mean or average of THIS set of numbers is found by adding the 6 numbers and dividing by 6. 90/6 = 15.
(1st way) 21, 24, 25, 25, 25 - [21+24+25+25+25] / 5 = 120 / 5 = 24 (mean) (median = 25 - middle #) ~ (2nd way) 18, 24, 25, 26, 27 - [18+24+25+26+27] / 5 = 120 / 5 = 24 (mean) (median = 25 middle #) ~ (3rd way) 10, 20, 25, 30, 35 - [10+20+25+30+35] / 5 = 120 / 5 = 24 (mean) (median = 25 middle #)
If the numbers are all different, then 25C5 = 25*24*23*22*21/(5*4*3*2*1) = 53,130.
Mean is the average of all the numbers.Sum of all the listed numbers = 584Total of all the listed numbers = 25584 / 25 = 23.36Mean = 23.36
24 and 25 or -25 and -24
There is no such data set for 7 numbers. With the maximum at 35 and the range 20, the mode (average) will always be more than 21, even with the lowest numbers possible. e.g. 15 15 15 24 24 24 35 sums to 152, which is 5 higher than the necessary 147 (21 x 7) So you need at least 11 numbers such as 15 15 15 15 15 24 24 24 24 25 35, keeping 24 as the median and the average 21 (231/11).
to find the average (a.k.a mean) of any set of numbers you add all of the numbers up, then divide by however many numbers there are. for ex: 2,7,5,9,4 1st step: 2+7+5+9+2= 25 2nd step: 25 divided by 5= 5 average equals=5
