Answer:
-5 1/3
Step-by-step explanation:
This is how it should be shown
Answer:
x=-26
Step-by-step explanation:
Distributive property first (both sides)
you would get
4x+2 = 3x-24
next you will subtract 3x from both sides
1x+2=-24
add 24 to both sides
1x+26=0
move 26 to the other side but since you flipped it you have to make it negative
x=-26
Answer:
k = 63
Step-by-step explanation:
k/3 - 9 = 12
isolate variable + 9 both sides
k/3 = 21
multiply both sides by three, therefore
k = 63
check:
63/3 - 9 = 12
21 - 9 =12
12 = 12
hope this helps!
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.
