1.) in a sequence there are one 1’s, two 2’s, and three 3’s and so on up to ten 10’s. find the mean, median and mode is the sequence. 2.) the mean of three different positive integers x, y and z is 15. if y is six times x then what is the least possible value of z? 3.) the mean of a set of five positive integers is 1.5 times the median. if three of the integers are 24, 52, 86 and one of them is the median what is the sum of all distinct possible sums of the other two integers? 4.) the mean of one set of five numbers is thirteen. the mean of another set of six numbers is twenty four. what is the mean of the entire set of eleven numbers?
