The mean is (4+6+8+17+x)/5=(35+x)/5.There are three possibilities for the median: it is either 6,8, or x. Let's start with 6. (35+x)/5=6 has solution x=-5, and the sequence is -5,4,6,8,17, which does have median 6, so this is a valid solution.Now let the ...
which has median 8. This case is therefore again not valid. Hence the only possible vaue of x is (A)−5.结果一 题目 What is the sum of all real numbers x for which the median of the numbers 4, 6, 8, 17, and x is equal to the mean of those five numbers?( )A.−5B....
