Not completely sure of what this question is asking, but the orientation is the same. The actual triangle moved diagonally.
An experimental study involves the researcher seeking to affect the results on purpose. The given situation is an observational study.
<h3>What are surveys, experiments, and observational studies?</h3>
- Surveys are one type of observational study since the researchers have no control over the results. Statistical surveys collect data from a sample group in order to learn more about the overall population.
- The sample population being examined is measured, or surveyed, in observational research. The researcher watches the individuals and measures variables but makes no attempt to influence the population or intervene in the study.
- In contrast to an observational study, an experimental study involves the researcher seeking to affect the results on purpose. The objective is to find out what influence a certain therapy has on the result.
Since the researcher needs to find if a certain medicine improves the symptoms of the flu, therefore, the objective is to find out what influence a certain therapy has on the result. Hence, the given situation is an observational study.

Well 25% is the same as .25 or 1/4. So first you need to add X and Y so X+Y and since it is both you choose D
Answer:
y = 3
Step-by-step explanation:
2x - 5y = 1 ----------------(i)
-3x + 2y = -18 ---------------(ii)
(i) * 3 6x - 15y = 3
(ii)*2 <u> -6x + 4y = -36</u>
add==> -11y = -33
y = -33/-11
y = 3
Answer : 60 degrees
Explanation: All triangles's angles add up to 180. Since all angles are equal, you can divide 180 by 3. 180/3 is 60
