Step-by-step explanation:
2tan 30° / 1 + tan² 30° =
2(⅓√3) /1 + (⅓√3)² =
⅔√3 / 1+ ⅓ =
⅔√3 / 4/3 =
2/4 √3 =
½√3 = sin 60° (proven)
6x = 30
x = 30 / 6
x = 5

Answer:
2 Six graders: 6/55 chance
2 Seventh graders: 21/55 chance
Step-by-step explanation:
Total: 11 students
6 graders: 4
4/11 for first student and 3/10 for second
4/11 * 3/10 = 12/110 = 6/55
7 graders: 7
7/11 for first student and 6/10 for second
7/11 * 6/10 = 42/110 = 21/55
