Hi there!
A)
We can evaluate an integral to solve:
[tex]\int\limits^{10}_0 {2 + 0.4t^{2}} \, dt = 2(10) + 4/30(1000) = 153.333 L[/tex]
B)
Use the FTC to solve:
F(0) - ∫(0 to x min)f(t) = F(x) = 0
[tex]75 - \int\limits^{t}_0 {2 + 0.4t^2} \, dt = 0[/tex]
Solve:
[tex]75 = \int\limits^{t}_0 {2 + 0.4t^2} \, dt[/tex]
Evaluate:
[tex]75 = 2t + 4/30t^{3}[/tex]
Use a graphing utility to solve:
t = 7.65 min
C)
Use the slope formula to find the AROC:
f(10) - f(0) / 10 - 0 = 42 - 2 / 10 - 0 = 4 L/m²
For each of the following, come up with a hypothesis to explain the given fact. Explain why your hypothesis is adequate and indicate how you would tell whether the hypothesis is true. In other words, how would you test your hypothesis?
1. When we spend a lot of time looking forward to something, and expect to enjoy it, we are often disappointed.
Hypothesis:
Testing Procedure:
2. In midterm elections (those held midway through a president’s term), the president’s party usually loses seats in Congress.
Hypothesis:
Testing Procedure:
Answer:
1. Hypothesis: High expectations in a situation generate frustration.
Testing Procedure: Interview some volunteers and ask them to describe their expectations about a given situation. Reproduce the situation below the volunteers' expectations and ask them to describe the emotions they felt when living the experience below expectations.
2. Hypothesis: The president-elect's party loses voters, because of the agenda the president is following that disappoints the voters he had.
Testing Procedure: Select a group of volunteers who voted for the president-elect and ask them to explain their level of satisfaction with the current government and how likely they are to vote for the president-elect's party candidates in midterm elections.
Explanation:
In a scientific experiment, the hypothesis is an assumption that the researcher makes about what will be researched, that is, the hypothesis is something that the researcher thinks happens and that he will prove that it is true or not through texts that make up the experiment. These tests will generate data, which the researcher will evaluate and be able to interpret, generating a conclusion. This conclusion is able to show whether the researcher's hypothesis was correct or not.
