Answer:
Cos y = t / 8
Step-by-step explanation:
Using the hints given in the question, the omitted tribagke will look like the triangle attached on the picture ;
From trigonometry :
Sin y = opposite / hypotenus
Sin y = s / 8
Opposite side = s ; hypotenus = 8
Tan y = opposite / Adjacent
Tan y = s / t
Adjacent side = t
Then ;
Cos y = Adjacent / hypotenus
Hence,
Cos y = t / 8

Step-by-step explanation:
2x -6 ≥ 6(x-2)+8
Distribute
2x - 6≥6x -12+8
Combine like terms
2x - 6≥6x -4
Subtract 2x from each side
2x-6-2x ≥6x-2x-4
-6 ≥4x-12
Add 4 to each side
-6+4 ≥4x-4+4
-2 ≥4x
Divide by 4
-2/4 ≥4x/4
-1/2≥x
Closed circle at -1/2

The samples he chose may not be a representative sample because the number of students per foreign language class may not be the same. One class may have a very large number of students while another may have only a few. Taking equal number of students per class is not a representative sample.<span />
Step-by-step explanation:
- In the line 2, only variables were operated with a reduction of similar terms in each side of the equation, giving as result -4x at one side, and 2x at the other side.
- In the line 3, terms with variables were joined together in one side of the equation, and then, they were operate it, given as result -6X.
