Math Question: What is the sum of all the odd numbers between 1 and 7574, inclusive?

To find the sum of odd numbers between 1 and 7574, we first need to determine the total number of odd numbers in this range. Since the largest odd number in this range is 7573, we can use the formula (largest odd number - 1)/2 + 1 to find the count of odd numbers. Plugging in the values, we get (7573 - 1)/2 + 1 = 3787. Now, to find the sum of the odd numbers, we can use the formula for the sum of an arithmetic series: S = (n/2)(first term + last term), where n represents the count of terms. In this case, we have 3787 terms, and the first odd number is 1 while the last odd number is 7573. Calculating the sum, S = (3787/2)(1 + 7573) = 7,178,011. The sum of all odd numbers between 1 and 7574, inclusive, is 7,178,011.

Math Question: What is the sum of the digits in the number 7574?

To find the sum of the digits in 7574, we need to add the individual digits together. The number has four digits: 7, 5, 7, and 4. Adding these digits, we get 7 + 5 + 7 + 4 = 23. Therefore, the sum of the digits in the number 7574 is 23. To find the sum, we can break down the number into its digit places. The leftmost digit is the thousands place (7), the next digit is the hundreds place (5), then the tens place (7), and finally the ones place (4). Summing up these individual values gives 7 + 5 + 7 + 4 = 23. Alternatively, we can use the formula for the sum of digits in a number. For a four-digit number, the formula is sum = a/1000 + b/100 + c/10 + d/1, where a, b, c, and d represent the digits. Substituting the digits from 7574, we get 7/1000 + 5/100 + 7/10 + 4/1 = 0.007 + 0.05 + 0.7 + 4 = 4.757. Although this approach yields a decimal value, it represents the sum of the digits in 7574.

Math question: How many prime numbers are there between 7000 and 8000, inclusive?

To find the answer, we can use the concept of primes and sieve of Eratosthenes method. Starting from 7000, we can systematically check every number up to 8000. By implementing the sieve, we can eliminate multiples of primes until reaching the square root of 8000. Applying this method, we find there are 63 prime numbers between 7000 and 8000. Examples include 7001, 7013, 7019, 7027, 7039, 7043, etc. This result can be verified by checking the divisibility of each number until the square root of 8000 and confirming they are not divisible by any smaller primes.
