The side length of the regular hexagon is determined by first calculating the area of an equilateral triangle with a perimeter of 36 inches. The calculations lead to a side length of the hexagon being 2 6 ​ inches. Therefore, each side of the regular hexagon measures 2 6 ​ inches.

Jawab:Penjelasan dengan langkah-langkah:Tentu, mari kita hitung persamaan garis regresi dari data yang Anda berikan.Data:Waktu Belajar: 10, 15, 20, 12, 8, 16, 14, 22, 8, 16, 14, 22Nilai UTS: 92, 74, 84, 81, 85, 80, 84, 80, 84, 80, 74, 80Langkah-langkah Perhitungan:1. Hitung Rata-rata:Rata-rata Waktu Belajar (X̄) = (10 + 15 + 20 + 12 + 8 + 16 + 14 + 22 + 8 + 16 + 14 + 22) / 12 = 15Rata-rata Nilai UTS (Ȳ) = (92 + 74 + 84 + 81 + 85 + 80 + 84 + 80 + 84 + 80 + 74 + 80) / 12 = 81.082. Hitung Variabel (X - X̄) dan (Y - Ȳ):Ini adalah selisih antara setiap nilai waktu belajar dan nilai rata-ratanya, serta selisih antara setiap nilai nilai UTS dan nilai rata-ratanya.
