Answer:
Systematic-sampling method is the right answer.
Step-by-step explanation:
A method of sampling in which the sample members are selected from a larger population according to a random starting spot but with a fixed, interval, is known as the systematic sampling method.
We can use the systematic sampling method in the given situation. Individual sample members are chosen at regular intervals from the sampling data. We use to chose the intervals to ensure enough sample size. The main advantage of using this method is that it is more convenient and it is easy to administer. The benefit of using this method will be that the number of aspen trees will be sampled from all across the national park.
More than one triangle because it has to measure up to 180°
81 + 52 + 47 = 180
(Example) If you had a triangle that has the measurements 123 and 60 it would add up to be 183 so it would not be possible because the sum of all triangles cannot exceed 180°

100%-28% = 72%
Then multiply the percent left by the total number of milligrams of caffeine
130*.72 = 93.6 mg
