Method 2. (Picture 3)
ΔLOM and ΔMON are isosceles triangles. Therefore the two angles opposite the legs are equal.
The sum of the internal angles in each triangle is 180°. Thereofre in ΔLMN we have:


The dependent variable is money
614.40 because 204.80 divided by 4 is 51.20 and 51.20 multiplied by 12 is 614.40
Answer:
The answer is "Option a, Option b, and Option d".
Step-by-step explanation:
In the given question it is used to stratifying the sampling if the population of this scenario it flights takes off when it is divided via some strata.
-
In option a, In this case, it stratified the sampling, as the population of planes taking off has been divided into the days of the week.
-
In option b, It also used as the case of stratified sampling.
-
In options c, it is systematic sampling, that's why it is wrong.
-
In option d, It is an example of stratifying the sampling.
67.65 + 57.93 = 125.58
200.00 - 125.58 = $74.42 change back
