There can be a lot of set of three numbers which can have a mean as 45
one of the solutions is
sum of no./no. of numbers=mean
sum of no =45 x 3=135
A set of such no can be 44,45,46 as they hav their sum as 135 and hence their mean as 45
Assuming you mean which 5 consecutive numbers added give a total of 45... One answer would be 7,8,9,10 & 11
45
The mean is 76.5
45 + 75 + 63 = 183 as there are 3 numbers divide 183 by 3 = 61
45
mean = 270 divided by 5 = 54 median = 45 mode = 45
you add up all the numbers in the sequence then divde your answer by how many numbers there are in the sequance so if you had the numbers 20, 19, 7, 45, 2 you would add them up which equals 93 then divide it by 5 (how many numbers in the sequence) so your answer would be 18.6
The question is incorrect since the mean of 45 57 0 and 3 is not 30. And the value of 45 is 45, whatever its mean when combined with other numbers. Similarly, the value of 57 is 57, whatever its mean when combined with other numbers; etc.
In any given set, the mean is the average, which is the total of the numbers divided by how many numbers there are. Ex. (10, 17, 20, 45, 68) 68 + 45 + 20 + 17 + 10 = 160 There are 5 numbers in this set. 160/5 = 32 The mean is 32.
To calculate the odds of winning lotto where choose say 6 numbers out of 40 for example the calculation is 40X39X38X37X36X35 divided by 6X5X4X3X2X1 or about 3.8 million to 1 on any one line. If you have 45 numbers to choose from it would be 45X44X43X42X41X40/6X......etc or about 8.2 million to 1.
In any given set, the mean average is the total of the numbers divided by how many numbers there are. Ex. (10, 17, 20, 45, 68) 68 + 45 + 20 + 17 + 10 = 160 There are 5 numbers in this set. 160/5 = 32 The mean is 32.
