Answer:
A/C
Step-by-step explanation:
Since the sum of the angles in a triangle equals 180°, and angle C is 90°.
That means angles A and B add up to 90°, that is, they are complementary angles. Therefore the cosine of B equals the sine of A.
We saw on the last page that sin A was the opposite side over the hypotenuse, that is, a/c. Hence, cos B equals a/c.

Answer:
The correct option is (C) convenience sample.
Step-by-step explanation:
Convenience sampling is a kind of non-probability sampling, i.e. all items does not have an equivalent chance or probability of being selected. This type of sampling method does not comprises of random collection of items.

She did so because her staff did not have that much time in hand and it is quite convenient to check the last 200 vouchers.
This is because it is quite easy to review the last 200 payroll vouchers since they would be the most recent ones and quite easily accessible.
So, the sampling method used by the Chief Financial Officer of Harrison Haulers, Inc. is Convenience sampling.
Thus, the correct option is (C).
