Identify the sampling procedure used in this situation. Sandra, a second year facilitator of the same school where Paula works,
is also assigned to look into the study habits of the second year level which
has 7 sections ranging from 43 to 45 students per section. But unlike Paula,
she asked the school registrar a copy of the 2nd year students' ranking from
highest to lowest grades. She then got the names of every 10th student on
the list and scheduled an interview for each selected student.​

Juliana says that she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6: 10. which statement explains whether juliana is correct? she is correct because she can multiply 6 and 10 by any number to form an equivalent ratio. she is correct because 6: 10 can be written as 1: 2 and there are an infinite number of ratios for 1: 2. she is not correct because the multiplication table does not include multiples of 10. she is not correct because 6: 10 is equivalent to 3: 5 and there are only 9 ratios in the multiplication table that are equivalent to 3: 5.

What is the explicit formula for this sequence? -7, -4, -1, 2, a.) an = 8 + (b - 1)3 b.) an = -7 + (n - 1)3 c.) an = 3 + (n -1) (-7) d.) an = -7 + (n - )
