Math question: What is the sum of the digits of the number 9812?

To find the sum of the digits in the number 9812, we break it down and add them up: 9 + 8 + 1 + 2 = 20. Therefore, the sum of the digits in the number 9812 is 20.

Math question: What is the sum of the first 20 even numbers greater than 4900?

To find the sum of the first 20 even numbers greater than 4900, we start by identifying the first even number larger than 4900, which is 4902. From there, we add 2 repeatedly to find the consecutive even numbers. The sequence is: 4902, 4904, 4906, 4908, 4910, 4912, 4914, 4916, 4918, 4920, 4922, 4924, 4926, 4928, 4930, 4932, 4934, 4936, 4938, 4940. Adding up these numbers, we find their sum to be 98,120.

Math Question: If you randomly rearrange the digits of the number 9812 to form a new four-digit number, what is the probability that it will be divisible by 7?

To calculate the probability, we need to determine the total number of possible arrangements of the digits. Since we have four different digits (9, 8, 1, and 2), there are 4!=24 ways to arrange them. Now, let's find the number of four-digit arrangements divisible by 7. Since 7 is a prime number, we only need to check the divisibility of the last three digits since the leading digit doesn't affect divisibility by 7. By analyzing all 3! = 6 permutations of the last three digits (812, 821, 182, 128, 218, 281), we can see that none of them are divisible by 7. Therefore, the number of four-digit arrangements of 9812 divisible by 7 is 0. Consequently, the probability of randomly rearranging the digits of 9812 to form a four-digit number divisible by 7 is 0/24 = 0.
