حل السؤال 17، 4MA1/2FR يونيو 2020: المتوسط والوسيط والمنوال والمدى

1. 1The median is 8, so the third number when ordered must be 8.
2. 2The mode is 5, so 5 must appear more than once; at least two 5s.
3. 3The range is 10, so the difference between the largest and smallest number is 10.
4. 4The total sum is 45.
5. 5Start with two 5s and include 8 as the median: 5, 5, 8, _, _.
6. 6Smallest number is 5, so largest must be 5 + 10 = 15.
7. 7Now we have: 5, 5, 8, _, 15.
8. 8Sum so far: 5 + 5 + 8 + 15 = 33.
9. 9Missing number: 45 − 33 = 12.
10. 10Final numbers: 5, 5, 8, 12, 15.

Answer5, 5, 8, 12, 15
