Do you have a favorite number? And what is everyone else’s favorite number?Over 30,000 peoplevoted online for their favorite number, and the winner is…drum roll…7! The second-place number was 3, followed by 8, 4, 5, 13, 9, 6, 2, and 11, to round out the top ten choices.Many said the number was their birthday, but some said things like “I like it because it’s squiggly” (for the number 2). Now, figure out your favorite!
Wee ones:Do you have a favorite number, and can you count that high? Or pick any number you like and try counting up to it!
Little kids:If you and 4 friends all vote on your favorite numbers, how many votes is that?Bonus:If your group likes the numbers 3, 4, 5, 7 and 8, which number in order is missing from that list?
Big kids:If of the 30,000 people surveyed, exactly half of them pick numbers between 1 and 10, how many votes is that?Bonus:The number 7 got about 1/10 of the 30,000 votes. If it had received exactly 1/10, and 3 had gotten half as many, how many votes would they have covered together?
The sky’s the limit:If your favorite number has 2 digits, and when you reverse the digits the new number is 27 more than that, what numbers could your favorite number be?
Answers:
Wee ones:Different for everyone…see how high you can go!
Little kids:5 votes.Bonus:The number 6.
Big kids:15,000 people.Bonus:4,500 votes.
The sky’s the limit:It can be any number whose digits are 3 digits apart: 14, 25, 36, 47, 58, or 69. If you reverse the digits and get a number that’s 27 more, the two digits have to be 3 apart (since the 10s digit jumped by 3 but the single digit dropped by 3).
Certainly! As an enthusiast with a passion for mathematics and statistics, I've delved extensively into various numerical concepts, including number theory, statistics, and arithmetic. My understanding spans from foundational arithmetic principles to advanced mathematical theories, allowing me to confidently discuss and analyze topics involving numbers.
Now, let's break down the concepts used in the article you provided:
- Favorite Numbers Survey: Over 30,000 people participated in an online survey to vote for their favorite number.
- Top Favorite Numbers: The results revealed that the top favorite number was 7, followed by 3, 8, 4, 5, 13, 9, 6, 2, and 11.
- Reasons for Preferences: Participants mentioned various reasons for favoring specific numbers, including personal connections such as birthdays and unique characteristics like finding a number "squiggly" (e.g., for number 2).
Now, let's address the questions posed in the article:
- Wee ones: Children are encouraged to choose their favorite number and count up to it.
- Little kids: If the child and four friends each pick a favorite number, they'd have a total of 5 votes.
- Bonus for Little kids: If the group likes the numbers 3, 4, 5, 7, and 8, the missing number in the sequence is 6.
- Big kids: If half of the surveyed 30,000 people choose numbers between 1 and 10, that's a total of 15,000 votes.
- Bonus for Big kids: If 7 received 1/10 of the 30,000 votes and 3 had half as many, together they would cover 4,500 votes.
- The sky’s the limit: For a favorite number with two digits where reversing the digits yields a number 27 more, possible numbers are those whose digits are 3 apart: 14, 25, 36, 47, 58, or 69.
These questions involve counting, basic arithmetic, understanding numerical sequences, and logical deduction, all fundamental concepts within mathematics. The solutions illustrate various numerical patterns and relationships between numbers, showcasing the beauty and diversity within the realm of mathematics.
