83
The average of 79, 84, 82, and 87 is 83.
There are 83 days in a normal year, 84 days in a leap year: In 2010 there were 83 days In 2011 there were 83 days In 2012 there were 84 days In 2013 there were 83 days In 2014 there were 83 days In 2015 there were 83 days In 2016 there were 84 days
84
There is an infinite number of possible answers. If you have 83, 83, 83, etc. the mean is 83. If you have 82, 83, and 84, the mean is 83.
83 x 1 82 + 1 84 - 1 83 ÷ 1
This is a combination problem. Chose 2 from 84. 84C2 = (84 * 83)/2 = 42 *83 = 3486 ways.
83, 84, 85, 86, 87, 88
84*83/2 = 3486 Each of 84 people can hold a conversation with any one of the other 83 people. So 84*83. But a conversation between A and B is the same as a conversation between B and A so divide the number by 2.
nope. but 83 and 89 are
not at all! She is 83, almost 84! (:
13-11-84-01=13-(11+84+1)=13-(96)=-83
