<h3>Answer:</h3>
- A — 1
- B — ∑[k=0..2] 15Ck(.24^k)(.76^(15-k))
- D — 12 and 3.1
- A — 0.1091
- B — 0.83 ...
<h3>Explanation:</h3>
1. The probability is 0.52 that the officer will pull over a driver and then the expected number more. So, if x is the expected number of drivers pulled over until one is not texting, we have ...
... x = 0.52(1+x)
... 0.48x = 0.52
... x = 0.52/0.48 = 13/12 = 1 1/12 ≈ 1 . . . . matches selection A
(<em>Comment on this result</em>: I find it interesting that these are the odds in favor of finding a driver who texts. That is, if the probability of texting is 0.98, the odds are 49:1 that a driver will be texting, and the expected number of pull-overs is 49.)
2. The probability of at most 2 being cured is the probability of 0, 1, or 2 being cured. You need to add up those probabilities. The sum in answer selection B does that.
3. The mean of a binomial distribution is ...
... μx = np = 60·0.2 = 12
... σx = √(np(1-p)) = √(12·0.8) ≈ 3.0984
These match selection D.
4. 20C14(0.8^14)(0.2^6) = 38760·.043980·0.000064 ≈ 0.109100 . . . matches A
5. mean(x) = 0.94; mean(x^2) = 1.58, so ...
... σx = √(1.58 -0.94²) ≈ 0.83 . . . . matches selection B
Answer: The U.S. Senate determines the budget of the U.S. judiciary.
Explanation:
From the question, we are informed that a lobbying group interested in shaping the federal judiciary spends large amounts of money on the Senate races in the U.S.
Out or the options given, the correct option will be because the U.S. Senate determines the budget of the U.S. judiciary. Th judiciary is in charge of interpreting the law.
Since the budget is determined by the U.S senate, this will be the reason for the lobbying group spending large amounts of money on U.S. Senate races.
The answer is; gender bias
Discrimination of women of women in society may be conscious or unconscious, subtle or obvious. This is attributed to inculcated cultural tendencies, over history, that tend to treat the female gender as inferior to the male gender.
Light waves are transmitted across the cornea and enter the eyes through the pupil.
<h3>
FURTHER EXPLANATION</h3>
The eyes and the brain are important in helping people see. Light passes through the eyes and this light gets transformed into electrical signals which are sent to the brain that helps make sense of the object that is seen.
<h3 /><h3>How People See</h3>
- Light is incident on an object (or strikes an object). Some of it get absorbed, some are reflected into a human's eye.
- Light that bounces off the object is transmitted across the cornea, the transparent outer layer of the eye. It refracts the light and makes things look sharp and clear.
- Then the light enters the pupil which is the opening in the eye controlled by the iris or the colored part of the eye. The iris changes the size of the pupil and controls the amount of light that enters the eye. When there is bright light, the pupil becomes smaller. In dim light, the opposite happens and the pupil becomes bigger.
- At the back of the pupil is the lens which again helps focus the light. Its shape changes depending on the distances of the objects that is being looked at.
- The light rays are focused by the lens so that they all converge in the retina which is at the back of the eye. The retina has many specialized cells which are sensitive to light. These cells transform light energy into electrical signals or nerve impulses which form a rough inverted image of the object the person is looking at.
- The electrical signals travel to the brain through the optic nerve. The brain turns the image upright and adds more detail to the vision.

Answer:
Part A:
<u>Encoding failure</u>: This applies to the the AP exam because if the terms are not consciously read and studied, it won’t be encoded, and it won’t be remembered. This influences failure on the exam, rather than success.
<u>Predictive validity</u>: Regarding the AP exam, the test is made to predict the future behaviour of the student within the course. Therefore, if the test score is high, the retention of content in the future should be higher than that of a person with a lower test score. The same can be said for the AP course or the AP practice tests. These resources are made to predict what the test score is most likely to be, if the test has predictive validity.
<u>Distributed practice</u>: This will influence success on the AP exam because it allows for better recall rather than recognition, so writing the portion will be more successful.
<u>Proactive interference</u>: This could influence failure on the AP exam because previously learned information such as learnings from biology class or chemistry class can interfere with the newly learned information from psychology, especially since these subjects can cross content.
Part B:
<u>Procedural memory</u>: In a performance task, procedural memory comes in handy because writing letters or typing is easy without thinking about it.
<u>Acetylcholine</u>: This can lead to failure on the performance task because procedural memory might be impaired or recognition of everyday material might exacerbate the difficulty of the already challenging task.
<u>Emotional intelligence</u>: Having high emotional intelligence would influence success in the performance task because it allows for greater creativity when thinking of issues about others and when solving issues.
