Which scenario would be most appropriate to study using a natural experiment?
I. the effects of an herbicide on human health
II. the influence of sleep on exam performance
III. the effects of an earthquake on blood pressure
a) III only
b) I and III
c) I only
d) II only
Answer:
c) I only
Explanation:
This is because, herbicides which is applied in plants for its protection could only be studied through natural experiment. This study will determine its effects on human and help comes to a logical conclusion if it was a harmful effect or not. The natural experiment would be a small sized controlled experiment in-order to minimize the consequences of such study.
Using a telescope you detect an asteroid is moving towards Earth. The total time for radio waves transmitted to the space rock and back to Earth is 7 seconds. What is the approximate distance to the asteroid?
Answer:
The approximate distance to the asteroid is 1,049,273.603 kilometres
Explanation:
Radio waves are waves due to electromagnetic radiation that travel at the speed of light, which is 299,792,458 m/s
The parameters given are;
Object detected moving towards Earth = An Asteroid
The total time for the radio waves to travel to the space rock and back = 7 seconds
The speed of radio waves = 299,792,458 m/s
Speed = Distance/Time
The distance traveled by the radio wave in 7 seconds = 2 times the approximate distance to the asteroid, d
The distance traveled by the radio wave in 7 seconds = Time × Speed = 2×d
∴ 2×d = 7 s × 299,792,458 m/s = 2,098,547,206 meters
d = 2,098,547,206 meters/2 = 1,049,273,603 meters = 1,049,273.603 kilometres
The approximate distance to the asteroid = 1,049,273.603 kilometres.

You are marking a rectangular paintball zone that must be 34 meters wide and have a perimeter of at least 140 meters but not more than 260 meters. Find the interval for the length $x$ of the rectangular paintball zone. Write your answer in interval notation.
Answer:
36m <= L <= 96m
Explanation:
Since the paintball is rectangular, the formula for the perimeter P of a rectangle is:
P = 2(L + B)
Where L = length
B = width
Given that the rectangular paintball zone must be 34 meters wide and have a perimeter of at least 140 meters but not more than 260 meters.
When the perimeter is least, the length will be achieved by substituting the perimeter and the width into the formula. That is,
140 = 2(L + 34)
L + 34 = 140/2
L = 70 - 34
L = 36m
When the perimeter is maximum, that is, 260m. Substitute it and the width into the formula
260 = 2(L + 34)
L + 34 = 260/2
L + 34 = 130
L = 130 - 34
L = 96.
Therefore, the interval for the length of the rectangular paintball zone will be:
36m to 96m. That is
36m <= L <= 96m

Which of the following map projections is MOST closely identified with distorting shape and size? A cylindrical projection A Mercator projection A conical projection A Robinson projection An azimuthal projection
Answer:
A Mercator projection
Explanation:
Mercator projection is defined as a map projection was found in 1569 by Flemish cartographer Gerardus Mercator.
The Mercator projection seems parallels around a cylindrical globe and meridians appears as straight lines, but there is distortion of scale near the poles which do not make it a practical world map.
Hence, the correct answer is "A Mercator projection".
Answer:
A Mercator projection is the correct answer
Explanation:
The Mercator projection was first presented by cartographer and Flemish geographer Gerardus Mercator in 1569. Later due to its unique representation of north as up and south as down while preserving the local angular relationships, it became the standard projection for use in navigation. One major drawback of Mercator projection is that it distorts distance and size as you get closer towards the pole.

Assume that your classmate suggested that both graphs represent constant opportunity costs because movement from combinations A to B, B to C, and C to D stays the same for each
economy. Explain why this is incorrect.
Answer:
The movement of the combinations, explained by your classmate, is presented in an equal way, which does not represent an opportunity cost. In order to be able to perceive a constant opportunity cost, the combinations should present different values, and the choice of one of them, would cause the loss of opportunity to submit to the results that would be obtained with the choice of the others. However, as all combinations are the same, choosing any one would give the same results.
Explanation:
A constant opportunity cost refers to the presentation of elements in a business that would happen differently from each other and that would present different profitable results in a constant and extended way, showing the value and benefits that each one has individually.
It should be noted that it's incorrect because movement of combination being presented in a equal way doesn't imply a constant opportunity cost.
A constant opportunity cost simply occurs when the opportunity cost is the same when the individual increases the production of a good.
In this case, the classmate suggested that both graphs represent constant opportunity costs because movement from combinations A to B, B to C, and C to D stays the same for each economy. This doesn't mean that there is a constant opportunity cost.

The amount of paper, R, recycled by a city with population p is given by =(). R is measured in tons per week, and p is measured in thousands of people. A. The city of Galveston has a population of 50,000 and recycles 7 tons of garbage each week. Express this information in terms of the function f. B. Explain the meaning of the statement (20)=3.
Answer:
a) f(50) = 7
b) for a population of 20000 people, the amount of paper being recycled is 3 tons.
Explanation:
A function shows the relationship between two or more variables (an independent variable and a dependent variable), relating the input to output. The independent variable does not depend on any variable and it is also the input while the dependent variable depends on other variables and it is the output
a) Since the function is given as R = f(p), a population of 50,000 and recycles 7 tons of garbage each week is represented as:
f(50) = 7
f(50) means 50000 people and the 7 means 7 tons
b) f(20) = 3 means that for a population of 20000 people, the amount of paper being recycled is 3 tons.

How did some students and tutors find shortcuts to learning? How did the Chinese government react to these shortcuts?
According to a different source, this question refers to the text "The Chinese Civil Service Exam System” by Ichisada Miyazaki.
In this text, we learn that the Chinese civil service examination system originated in Ancient China nearly fourteen hundred years ago. Therefore, it is one of the oldest examination systems in the world.
The system was intended to identify the most capable young men in China, and educate them so that they might become part of the government. However, this was a long, difficult and tedious process, and many students and tutors found useful shortcuts to learning. For example, rapid-study methods were devised, such as compiled collections of examination answers.
The Chinese government was aware of such methods, which were strongly condemned. Students who employed them were failed. The government also issued frequent prohibitions of the publication of such materials. However, the success of the business meant that such prohibitions were often unsuccessful.
Solve the following equation.
2x + 1 = 5
1. 2
2. 5
3. 8
Answer:
2
Explanation:
2x + 1 = 5
The solution to the above equation can be obtained as follow:
2x + 1 = 5
Subtract 1 from both side
2x + 1 – 1 = 5 – 1
2x = 4
Divide both side by the coefficient of x i.e 2
2x/2 = 4/2
x = 2
Therefore, the solution to the equation is 2.

Read the information under the heading, "How Many Senses?". Explain what astronauts experienced upon their arrival in space and on Earth and what this might tell researchers about the vestibular system. (Site 1)
Example Answer:
We know that all humans have five senses these are sight, taste, smell, hearing and touch. But actually, there is a “sixth sense” which is known as vestibular system.
Vestibular system helps us to sense our body movement combined with our ability to maintain body balance. A body has ability to sense and determine in which direction and with which speed the body is moving and with the help of this information body can maintain its balance. A blind man rely on his vestibular sense for this information. Body vestibular system is designed to work on the ground. So in space it can provide erroneous or disorienting information. Astronouts are trained for adaptation strategies to enter in a microgravity environment. When astronouts return back to earth in normal environment they feel dizziness and disorientation.
Hope this helps!
As humans, we basically have 5 senses which are the hearing, touch, sight, taste and smell.
It is learned that there is a sixth sense in human called the Proprioception. This sense has the ability to sense the orientation of our body in any environment. This sense helps the body sense movement and body balance.
What is the Vestibular system?
It is the sensory inner ear which helps the body to maintain posture. It coordinates the position of the head and movement of the eye.
This sense called vestibular system is designed to work on the ground. It allows one to keep track of the body even in space.
Due to this sixth sense, Astronauts are trained for adaptation strategies to get into the micro-gravity world and survive there.
This causes them (astronauts) to feel dizzy and disoriented when they return to earth.
