the mean median unique mode and range of a collection of eight integers are equal to 8. find the largest integer that can be an element of this collection.



the digits 1,2,3,4,5,6,7,9 are used to form four two-digit prime numbers with each digt uded exactly once. What is the sum of these four primes?

suppose that A,Band C are three numbers for which 1001C-2002A=4004 and 1001B=3003A = 5005. Find the average of the three numbers A,B, and C

1. Uniqe mode = 8 : So largest integer = 8

3. Divide equations by 1001:

C - 2A = 4, B = 3A = 5

(C-2A) + B + 3A = 4 + 5 + 5 = 14

A + B + C = 14

Average = 14/3
