If the mean of 3, 5, 8, k, 14 and 17 is 11, what is the value of k
58
38
19
11
967
Correct answer is C
To calculate Mean: add up all the numbers ⇒ 3+5+8+k+14+17 = 47 + k then divide by how many numbers there are ⇒ 6 The Mean is already given as 11 11 = (47 + k) / 6 Cross multiply to solve for k : k = (6 X 11) - 47 k = 19
