ACHIEVEMENTS EARNED DURING THE LAST QUESTION:0

## The Question of the Day - 20 points

Mr. Wolfeschlegelsteinhausenbergerdorff had his students practicing their math. He asked his kids to write as many different addition problems as they could where two whole numbers added up to 10. How many ways can two whole numbers add up to 10? Note that the addition problems a+b and b+a should be considered different problems.

Lucky Prime Hint: -24

## Previous Solution

The Lucky Prime number was 523. Removing all x's from the hint, we get: oasctlnn lla 3 isdtlg wnhso ni het doaknbrcug fo tshi kiwi. Unscrambling, we get: Contains all 3 digits whose in the background of this wiki (yeah, I know, bad grammar). Anyways, the background of this wiki is 2,3,5...... Using these 3 numbers as digits, we can only form one prime number, 523.

The solution was 11. if there are 7 numbers and the median is 84, then 84 is the middle number. Because of the dual mode, there are either two 78s and two 88s or three of each. if there were three of each the mean would not be 84 though, so there must be two of each. So we need to find possibilities for the last two numbers. A 7-number list with a mean of 84 would have a sum of 7(84)=588. The five numbers we know so far have a sum of 416. The remaining two numbers must have a sum of 455-416 = 172. One of the numbers must be bigger than 84 and one must be smaller. Possible pairs would be 83&89, 82&90, 81&91, 80&92, 79&93, 78&94, 77&95, 76&96,7 75&97, 74&98, 73&99, 72&100. That's 12 possible pairs for the remaining numbers except that one of the pairs include a 78 which would give the list three 78's and no longer a dual mode. So only 11 of the pairs would fit the 7- number list we are looking for. Good job Minipop56!
