Is 47 a triangular number?
47 is not a triangular number. Triangular numbers less than 100 are 1, 3, 6, 10, 15, 21, 28, 36, 45, 55, 66, 78, and 91.
What is the median of this set of numbers 60 63 68 80 91 91 100?
60 63 68 80 91 91 100? First place the terms in Rank Order. NB This has already be done. For the median you take the ABSOLUTE middle term. Which in this case is '80'. Notice there are three terms to the left of '80' and three terms to the right. NNB This is good for an odd number of terms. When there is an even number of terms , you take the middle two terms . Add then together and divide by '2'. Do for the above set of terms , we add an eighth term , say '110'. Then 60 63 68 80 91 91 100,110. We take the two middle terms '80' & '91'(80+ 91) / 2 = 85.5 ; rthis is the median term.
What is the median for 98 92 94 88 82 81 96 95 88 78 88 91 91 93 89?
To find the median of a set of numbers, you first need to arrange them in numerical order. Once you have them in order, the median is the middle number. If there is an odd number of values, the median is the middle number. If there is an even number of values, the median is the average of the two middle numbers. In this case, the numbers arranged in numerical order are: 78, 81, 82, 88, 88, 88, 89, 91, 91, 92, 93, 94, 95, 96, 98. Since there are 15 numbers, the median will be the 8th number, which is 89.
