Math Question: What is the sum of all prime numbers less than 1916?

To find the sum of prime numbers less than 1916, we need to identify all the primes up to 1916 and sum them up. Beginning with 2 as the first prime, we check every number up to 1916 to see if it is divisible by any number other than 1 and itself. After evaluating all the numbers, we find the primes to be: 2, 3, 5, 7, 11, 13, 17, 19, 23, ..., 1867, 1871, 1873, 1877, 1879, 1889, 1901, 1907, 1913. Adding them all up gives 48,564. Therefore, the sum of all prime numbers less than 1916 is 48,564.

Math Question: What is the sum of the first 20 positive integers minus the product of the factors of 1916? Explanation: To find the sum of the first 20 positive integers, we can use the formula for the sum of an arithmetic series: Sn = (n/2)(a + l), where Sn is the sum, n is the number of terms, a is the first term, and l is the last term. In this case, n = 20, a = 1, and l = 20. Sn = (20/2)(1 + 20) = 10(21) = 210 Next, we need to determine the factors of 1916. The prime factorization of 1916 is 2^2 * 479. Hence, the factors are 1, 2, 4, 479, 958, and 1916. The product of the factors is P = 1 * 2 * 4 * 479 * 958 * 1916 = 8,767,246,848. Finally, we can calculate the answer by subtracting the product of the factors from the sum of the positive integers:

210 - 8,767,246,848 = -8,767,246,638 (approximately). Therefore, the result is approximately -8.767 billion.

Math question: If a company increased its profit from $1916 in the first quarter to $x in the second quarter, and the percentage increase between the two quarters remained constant, what would the profit be in the fourth quarter?

To solve this, let's assume the percentage increase remains the same. So, the profit in the second quarter would be $1916 + (x% of $1916). If we apply the same percentage increase to the profit in the second quarter, the profit in the third quarter would be (profit in the second quarter) + (x% of (profit in the second quarter)). Finally, using the same percentage increase, the profit in the fourth quarter would be (profit in the third quarter) + (x% of (profit in the third quarter)). By substituting the initial value of $1916 into this equation, we can determine the profit in the fourth quarter.
