Assessment: WAEC SSCE - General Mathematics - 2004 (Objective) Subject: General Mathematics

Question 1 Report

Find, correct to two decimal places, the mean of 9, 13, 16, 17, 19, 23, 24.

Answer Details
To find the mean of a set of numbers, we need to add up all the numbers and divide by the total number of numbers. Adding the given numbers, we get: 9 + 13 + 16 + 17 + 19 + 23 + 24 = 121 There are 7 numbers in the set, so to find the mean, we divide the sum by 7: Mean = 121/7 = 17.29 (correct to two decimal places) Therefore, the answer is (b) 17.29.
