0.
The possible values for the ones digit of a number are the integers from 0 to 9. This means the ones digit can be any of the following: 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9. Each digit represents the last digit in a number's decimal representation.
FSK refers to a communications protocol in which different values of encoded (binary) information are signaled by modulating the frequency, and the start and stop of different bits are determined by the expected timing of each shift in frequency. If there was no shift, the next digit is the same as the previous digit (0 and 0 or 1 and 1), and if it shifted, then the next digit is the opposite (1 to 0 or 0 to 1).
0, 2, 4, 6, 8
No. To be divisible by 5 the last digit of the number must be one of {0, 5}. As the last digit of 7529 is neither 0 nor 5, it is not divisible by 5.
9
0 is a digit
In the number 8040930, the values of the digits are as follows: the digit 8 represents 8,000,000; the digit 0 represents 0; the digit 4 represents 400,000; the digit 0 represents 0; the digit 9 represents 90,000; the digit 3 represents 3,000; and the digit 0 represents 0. Each digit's value is determined by its position in the number.
9
There are 9C3 = 84 combinations.
4069
The ones digit in the number 100 is 0. This is because the ones digit is the last digit in the number, and in 100, that digit is 0.
1 is a single digit, 0 is the absence of a digit.
999
In the number 601199, the digit 0 is in the hundreds place, which means its value is 0 multiplied by 100. Therefore, the digit value of the 0 in this context is simply 0.
59
To form a three-digit number using the digits 0-9, the first digit cannot be 0 (as it would not be a three-digit number). Thus, the first digit can be any of the digits from 1 to 9 (9 options). The second and third digits can each be any digit from 0 to 9 (10 options each). Therefore, the total number of three-digit numbers is (9 \times 10 \times 10 = 900).
