Which set has the greatest range? {10, 14, 8, 19, 22, 13, 44}
{19, 16, 50, 18, 29, 23, 37}
{11, 9, 31, 29, 15, 17, 20, 24}
{12, 6, 24, 20, 44, 15, 29}

A is incorrect

Planet earth has a mass of 5.9726x10²⁴ kg.then: 5.9726x10²⁴ kg=100% of the total earth mass.if the water´s mass=5x10-4 % of the total mass, we can solve this problem by the rule of three.5.9726x10²⁴ %*10⁻⁴ %x=(5.9726x10²³ kg)(5*10⁻⁴  %) / 100 %=2.9863x10¹⁹ kganswer:   the mass of the planet´s water would be   2.9863 x 10¹⁹ kg.

Let us take option c(-3x + 6i)(x + 2i)-3x² - 6xi + 6xi + 12i²-3x² + 12i²we know that i² = -1-3x² - 12option c is the answer
