The formula to find the sum of consecutive numbers is x+x+2+x+4=66
In a simplified version is
3x+6=66
Now subtract the 6 from both sides and then divide both side by 3
x is 20. so the 3 numbers are 20, 22, and 24
We are going to rewrite the functions correctly:
f (x) = (1/4)
f (x) = (0.4) ^ x
f (x) = 4 ^ x
f (x) = (1/2) ^ x
We observe that we have functions of the form:
f (x) = A (b) ^ x
When
b> 1 The function grows
b <1 Function decreases
Therefore, the function that is growing is:
f (x) = 4 ^ x
Answer:
The function that is increasing is:
f (x) = 4 ^ x
option C)
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.
