AP Statistics teachers from across the country meet annually in Kansas City to score AP Statistics exams. One social event that many teachers participate in is the annual Prediction Fun Run. Prior to the race, the teachers predict how long it will take them to complete the 1.96-mile long course. During the event, they are timed and their actual finishing times are paired with their predicted times. Here is a scatterplot of the results. - Screen shot of the scatter plot and questions below!

The acceleration, in meters per second per second, of a race car is modeled by A(t)=t3−152t2+12t+10, where t is measured in seconds. What is the car's maximum acceleration on the time interval 0≤t≤6 ?

Answers

Answer:

  10.237 m/s²

Explanation:

The maximum acceleration will be at one end of the interval, or at a turning point in the interval. The turning points can be found where the derivative of acceleration is zero

  A'(t) = 3t^2 -304t +12

The quadratic formula will tell the zeros of this.

  t = (304±√(304^2 -4(3)(12)))/(2(3)) = (304 -√92272)/6 = (152 -√23068)/3

  t ≈ 0.0394891

Then the maximum acceleration is ...

  A(0.0394891) ≈ 10.23690 . . . . m/s^2

__

Additional comment

The maximum magnitude of acceleration is at t=6, where acceleration is ...

  A(6) = -5174 . . . . m/s^2

This is more than 500 g's in the negative direction, so the race car is not expected to survive that long.

__

The attached graph shows the acceleration curve for positive acceleration. The acceleration continues to decrease to a minimum of -5174 m/s^2 at the right end of the interval [0, 6].

Answer:

10. 237 m/s²

The car's maximum acceleration on the same time interval o<t<6.

A psychological researcher designs a study to determine whether positive feedback affects student test performance. The researcher requires each student enrolled in AP Psychology to participate. Students are divided into 3 groups—positive feedback, negative feedback, and no feedback. After completing the Module 1 FRQ, students in Group 1 are provided with positive feedback about their work and encouraged to keep working hard. Students in Group 2 are given criticisms of their writing and encouraged to rethink taking the course. Students in Group 3 are only given a numeric score, no written feedback. After reading the feedback, participants complete a survey measuring self-esteem and take their Module 1 Exam. Test scores are compared for the three groups. Following the test, all participants are debriefed and the true nature of the research explained. Results of the study indicate that participants who received positive feedback on their FRQs scored on average of 8 points higher than students who received negative feedback or no feedback at all. Which of the following violations to ethical guidelines is committed in the study described?
A) Confidentiality
B) Exposure to harmful procedures
C) Failure to debrief
D) Inappropriate use of deception
E) Voluntary participation

Answers

Answer: Option D

Explanation:

The test groups were divided into three groups the positive, negative and no feedback groups. The positive groups got better scores than compared to the negative feedback group and no feedback group.

The ethical guidelines that is violated is the inappropriate use of deception. The group that got negative feedback. Intentionally their morale was downsided.

Deception is not ethical in case of psychological experiments however, in some cases it is allowed to keep the experiment unbiased.

Answer:

B) Exposure to harmful procedures

Explanation:

You are mentally hurting the children's self esteem, hence unethical. Not A or C or D because you gave them a proper debriefing and confidentiality is fine. Not E because not all AP Psych students were forced; rather, they were given the option to participate. B is correct.

How did nationalism, colonialism, and imperialism and the Cold War influence the contemporary map of the 20tg century.

Answers

The correct answer to this open question is the following.

Although there are no options attached, we can say the following.

Nationalism, colonialism, and imperialism, and the Cold War influenced the contemporary map of the 20th century in that those elements created separation and division between countries. Wealthier nations used their expansionists ideas to invaded other nations, ethnicities created major separations and international conflicts, the greed of powerful nations exploited underdeveloped nations, polarized people, and confronted one political side against the other.

Nationalistic ideas radicalized ideas of "my country is better than yours and that gives the right to impose my conditions..." and this absurd idea was the foundation of more separation and exploitation of poor nations.

(c) The demographic data for country X for the year 2020 is provided in the table below.


Crude birth rate 381,000individuals

Crude death rate 241,000individuals

Net migration rate 21,000individuals

(i) Calculate the national population growth rate for country X. Show your work.


(ii) Using the rule of 70, calculate the doubling time for this population.

Answers

Answer:

1.6% growth rate

43.75 years = doubling time.

Explanation:

40-24 = 1616/1000 = 0.016 x 100 = 1.6% growth rate

70/1.6 = 43.75 years = doubling time.

Population growth rate is the rate at which the population of a country increases.

The population growth rate is 1.6%The population of country X will double after 44 years

Given

[tex]B = \frac{38}{1000}[/tex] --- birth rate

[tex]D = \frac{24}{1000}[/tex] --- death rate

[tex]N =\frac{2}{1000}[/tex] -- net-in migration rate

(a) The population growth rate

The population growth rate is:

[tex]r = B - D + N[/tex]

So, we have:

[tex]r = \frac{38}{1000} - \frac{24}{1000} + \frac{2}{1000}[/tex]

Take LCM

[tex]r = \frac{38 -24 + 2}{1000}[/tex]

[tex]r = \frac{16}{1000}[/tex]

[tex]r = 0.016[/tex]

Express as percentage

[tex]r = 0.016 \times 100\%[/tex]

[tex]r = 1.6 \%[/tex]

Hence, the population growth rate is 1.6%

(b) Number of years to double

Using the rule of 70, the number of years (n) to double is:

[tex]n = \frac{70}{r}[/tex]

So, we have:

[tex]n = \frac{70}{1.6}[/tex]

[tex]n = 43.75[/tex]

[tex]n = 44[/tex] -- approximated

Hence, it will take 44 years for the population to double

A child in the concrete operations stage can reason differently than can a child in the sensorimotor stage. For example, if shown two identical balls of clay, one of which has been rolled into a rope, an older child (one in the concrete operational period) might decide that the ball and the rope both have the same amount of clay. What kinds of reasoning do you think the older child might use to draw that conclusion?

Answers

Answer:

The child would be using the reasoning that allows him to understand reversibility operation and reciprocity operation.

Explanation:

Through the reversibility operation the child can understand that some things after being changed can return to their original state. In the case shown in the question above, the child was able that once the clay ball was rolled on top of the rope, he could redo his clay concentration and reaching the same amount of clay as the rope. We can also state that the child understands the concept of reciprocity operation, since she understands that the changes that the ball undergoes are a consequence of the amount of clay that the ball has.
