The sampling technique used is Simple Random Sampling option fourth would be the best choice.
<h3>What is simple random sampling?</h3>
Simple random sampling is a sampling strategy in which every item in the population has an equal probability of being chosen for the sample.
Simple random sampling selects a sample of objects at random from a population, with each item having an equal chance of being chosen.
Simple random sampling selects items for its sample from a table of random numbers or an electronic random number generator.
Thus, the sampling technique used is Simple Random Sampling option fourth would be the best choice.

Answer:
21 emperor penguins
Step-by-step explanation:
1. Convert 35% to decimal form
0.35
2. Multiply 0.35 by 60
21
3. The answer is 21
Answer:
Step-by-step explanation:
The cotangent of theta is:
For pi/2 < theta< pi
This means that the angle is in the second quadrant. In the second quadrant, the cosine is negative and the sine is positive. This means that the cotangent will be negative.
Secant:
In this question
So
Using cross multiplication
Now we apply the following trigonometric identity:
Since the angle is in the second quadrant, the sine is positive.
Finally, the cotangent:
