Eleven digit numbers are those in the range between 9,999,999,999 and 100,000,000,000 exclusive. There are 90,000,000,000 of these.

#include<iostream> #include<array> #include<sstream> std::array<int,10> get_frequency (int range_min, int range_max) { if (range_max<range_min) std::swap (range_min, range_max); std::array<int,10> digit {}; for (int count {range_min}; count<=range_max; ++count) { std::stringstream ss {}; ss << count; std::string s {}; ss >> s; for (auto c : s) { ++digit[c-'0']; } } return digit; } int main () { std::array<int,10> digit {}; digit = get_frequency(1, 89); std::cout << "In the range 1 to 89...\n"; for (int d {0}; d<10; ++d) { std::cout << "\tthe digit " << d << " appears " << digit[d] << " times.\n"; } } Output: In the range 1 to 89... the digit 0 appears 8 times. the digit 1 appears 19 times. the digit 2 appears 19 times. the digit 3 appears 19 times. the digit 4 appears 19 times. the digit 5 appears 19 times. the digit 6 appears 19 times. the digit 7 appears 19 times. the digit 8 appears 19 times. the digit 9 appears 9 times.

The smallest one in that range is 1,000. The largest one in that range is 6,000.All the numbers between 1,000 and 6,000 are 4-digit numbers. There are6,000 - 999 = 5,001of them.

1089.ExplanationA two digit palindrome will have the form AA, with A a digit between 1 and 9 (if A were zero, then this would not be a two digit number). So there are 9 possibilities for A and nine two-digit palindromes.A three digit palindrome will have the form ABA, with A a digit between 1 and 9 (if A were 0, this would not be a three digit number) and B a digit between 0 and 9. So there are 9 possibilities for A and 10 for B. There are thus 9*10=90 three digit palindromes.A four digit palindrome will have the form ABBA, with A a digit between 1 and 9 (if A were 0, this would not be a three digit number) and B a digit between 0 and 9. So there are 9 possibilities for A and 10 for B. There are thus 9*10=90 four digit palindromes.A five digit palindrome will have the form ABBBA, with A a digit between 1 and 9 (if A were 0, this would not be a three digit number) and B and C each a digit between 0 and 9. So there are 9 possibilities for A, 10 for B, and 10 for C. There are thus 9*10*10=900 five digit palindromes.Adding the above, we get a total of 9+90+90+900=1089 palindromes in the range.

The first 5 digit number is 10,000 and the last is 99,999. Thus there are 90,000 numbers between that range. Half of them are odd & half are even. 45,000 each

72. (with the range of two digit numbers being from 10 to 99).

I am less than 100 so the range is 01 - 99, but as I am divisible by 2 then I am even. As my tens digit and ones digit are the same then I am a 2 digit number so the range is now 10 - 98. The sum of my digits is 8, my tens digit and my ones digit are the same . . so the only solution is 44.

A 3.5 digit LCD (or LED) is a 3 digit display with a partial fourth digit that displays only 1 or 0 (or blank). Typical range is 000 to 1999, or 0000 to 1999.

3^333 ~ 7.61e+158 and is beyond the range of most calculators. I think "0" would be in the unit digit place.

In any given set, the mode is the number that appears most often. If no number appears more frequently than any other, there is no mode. The range is obtained by subtracting the smallest number from the largest.

For any integer greater than 5, where the units digit is 5 then that number can be expressed as the product of n and 5. As such, the number is composite. Therefore all numbers in the range 150 to 200 that have a units digit of 5 are composite,.

Its range, median, and mode.Range is the distance between the two farthest numbers out.Median is the middle number.And mode is the number that appears the most.

While the median is the middle number in a data set, and the mode is the number that appears most in that set. The range is the difference between the smallest and biggest number in your set. For example, in the set 1, 2, 3, 4, 5, 5, 8, the median is 4, the mode is 5, and the range is 8 minus 1 or 7.
