Answer:
The answer is "stratified sampling with equal allocation".
Step-by-step explanation:
Please find the complete question in the attached file.
The given question is an example of Random selection, in which the sampling is a testing process involving breaking into smaller groups called strata. In this, all stratification was established in graded or simple random sampling based on shared qualities or characteristics like salary or academic attainment of a Participant.
Answer:
5·c^2 + 30·c + 45 = 5·(c^2 + 6·c + 9) = 5·(c^2 + 2·1·3·c + 3^2) = 5·(c + 3)^2
This is a 30°-60°90° triangle, such that the ratio of the side lengths are
. If the length of the hypotenuse is 14, then the length of
is 7 units and
is
.
If you've never seen a 30°-60°90° triangle before, you can easily derive it by making an equilateral triangle (that is, with all angles of 60°) that has side lengths two. Then, you cut the triangle in half and solve for the hypotenuse using the Pythagorean Theorem.
