What is margin of error

Answers

Answer 1
The margin of error is a statistic expressing the amount of random sampling error in the results of a survey. The larger the margin of error, the less confidence one should have that a poll result would reflect the result of a survey of the entire population.

A bucket contains 72 red, 48 blue, 48 green, and 48 yellow crayons. The art teacher also has 120 pieces of drawing paper. What is the largest number of identical kits the art teacher can make with all of the crayons and all of the paper?

Answers

The art teacher can make a maximum of 24 identical kits using all the crayons and drawing paper for proper distribution.

To determine the largest number of identical kits the art teacher can make using all the crayons and drawing paper, we need to find the greatest common divisor (GCD) of the quantities.

The GCD represents the largest number that can divide all the quantities without leaving a remainder.

The GCD of the quantities of crayons can be found by considering the prime factorization:

72 = 2³ × 3²

48 = 2⁴ × 3

48 = 2⁴ × 3

48 = 2⁴ × 3

The GCD of the crayons is 2³ × 3 , which is 24.

Now, we need to find the GCD of the quantity of drawing paper:

120 = 2³ × 3 × 5

The GCD of the drawing paper is also 2³ × 3 , which is 24.

Since the GCD of both the crayons and drawing paper is 24, the art teacher can make a maximum of 24 identical kits using all the crayons and drawing paper.

Each kit would contain an equal distribution of crayons and drawing paper.

Graph the image of the quadrilateral belowusing a scale factor of k= 2/3, using theorigin as the center

Answers

Thus, the  image after the dilation of scale factor of 2/3 with origin for quadrilateral CDEF the are C'(0,0), D'(2, 4),  E'(6, 6),  F'(15, 3).

Explain about the scale factor:

The ratio between comparable dimensions of an object and a representations of that object is known as a scale factor in mathematics. The copy will just be larger if the scaling factor comprises an entire number. A fractional scaling factor means that the duplicate will be smaller.

Scaling up requires a scale factor that is bigger than 1.Scaling down requires a scale factor that is smaller than 1.

For the given coordinates quadrilateral CDEF, to find the coordinates of the image after the dilation of 2/3 with origin are-

Multiply each coordinate with 2/3:

C' - C(0*2/3,0*2/3) = C'(0,0)D' - D(3*2/3, 6*2/3) = D'(2, 4)E' - E(9*2/3, 9*2/3) = E'(6, 6)F' - F(15*2/3, 3*2/3) = F'(15, 3)

Thus, the image after the dilation of scale factor of 2/3 with origin for quadrilateral CDEF the are C'(0,0), D'(2, 4),  E'(6, 6),  F'(15, 3).

(d) State any two(2) properties of a semiconductor material.​

Answers

Answer:

Semiconductors are somewhere in-between conductors and insulators. This means that they are specific when it comes to conducting electricity meaning that their conduction of electricity varies based on their condition at the time.

For instance, they can conduct electricity when heated.

Properties:

    1. Perfect insulator at Absolute Zero.

As mentioned above, semi conductors are better at conducting electricity when they are heated. At Absolute zero - the lowest temperature possible -  therefore, these materials would conduct absolutely no electricity thereby making them perfect insulators.

   2. More resistance than Conductors but less than Insulators

As mentioned above, they have properties in-between those of insulators and conductors. One of those is their resistance. They can resist more than conductors but less than insulators.

Answers

Answer:

  9) D: (-4, 4]; R: [-6, -4]

  10) D: [-5, -5]; R: (-7, ∞)

Step-by-step explanation:

You want the domain and range of the relations shown on the given graphs.

Domain

The domain of a relation is the set of x-values for which it is defined. An open circle indicates that point is not included in either the domain or range.

Range

The range of a relation is the set of y-values that the relation produces. An open circle indicates the y-value at that point is not in the range.

9)

The graph has an open circle at x = -4 on the left, and a solid dot at x = 4 on the right. All of the x-values between these have corresponding y-values.

The domain is (-4, 4].

The bottom (minimum) of the curve lies on the line y = -6, so that is the lowest value in the range. The relation produces all y-values between -6 and -4. The solid dot at (4, -4) means -4 is included in the range.

The range is [-6, -4].

10)

The vertical line at x=-5 means -5 is the only value in the domain.

The domain is [-5, -5].

The vertical line extends upward from an open circle at y = -7. The open circle means -7 is not part of the range.

The range is (-7, ∞).

Answer:

9)  Domain:  (-4, 4]

    Range:  [-6, -4]

10)  Domain:  [-5]

    Range:  (-7, ∞)

Step-by-step explanation:

Definitions

An open circle indicates the value is not included in the interval.

A closed circle indicates the value is included in the interval.

An arrow shows that the function continues indefinitely in that direction.

Interval notation

( or ) : Use parentheses to indicate that the endpoint is excluded.

[ or ] : Use square brackets to indicate that the endpoint is included.

Domain & Range

The domain is the set of all possible input values (x-values).

The range is the set of all possible output values (y-values).

Question 9

From inspection of the graph, the minimum x-value is x = -4 and the maximum x-value is x = 4.

There is an open circle at endpoint (-4, -4).  Therefore, x = -4 is not included in the domain.

There is an closed circle at endpoint (4, -4).  Therefore, x = 4 is included in the domain.

Therefore, the domain of the relation is restricted:  (-4, 4]

From inspection of the graph, the minimum y-value is y = -6 and the maximum y-value is y = -4.

This maximum value is included in the range since there is a closed circle at (4, -4).

Therefore, the range of the relation is restricted:  [-6, -4]

Question 10

From inspection of the graph, the line is a vertical line at x = -5.

Therefore, the domain of the relation is restricted to x = -5:  [-5]

From inspection of the graph, the minimum y-value is x = -7.  

This minimum value is not included in the range since there is an open circle at (-5, -7).

There is an arrow on the other endpoint of the line, indicating that the line continues indefinitely in that direction.

Therefore, the range of the relation is restricted:  (-7, ∞)

Answers

The result of the expression 20 - 6 is 14.

To solve the given expression, 20 - 6, and isolate the variable, we need to clarify whether there is an equation involved. However, in this case, the expression does not contain any variable to isolate, and it is not an equation that needs balancing. It is a straightforward arithmetic expression.

Step 1: Start with the given expression, 20 - 6.

Step 2: Evaluate the subtraction operation: 20 - 6 = 14.

Step 3: The simplified expression is now 14. However, since there is no variable present, there is no need to isolate any variable.

This means that when you subtract 6 from 20, the answer is 14. Remember that isolating a variable and balancing an equation are relevant when dealing with equations that involve variables. In this case, the expression is a simple subtraction operation, yielding a constant value of 14 as the answer.

A piece of material measures 38 inches. Courtney cuts the piece of material into two pieces. One piece measures 19 inches. Write an addition equation that could be used to find the length, m, of the other piece of material.

Answers

Answer:

As a whole, the piece first measured 38 inches. No matter how many times you cut it, all of the pieces will still add up to 38 inches. You know that 19 inches is the length of one of the two pieces, so all you need to find is the other unknown piece. Add the two together, with m being the unknown length.

19+m=38

If you want to solve the equation, just subtract 19 from both sides.

19+m=38

m=19

If there are 1,000 future terrorists in a population of 400 million, and one of these 400 million is randomly selected, scrutinized by the system, and identified as a future terrorist, what is the probability that he/she actually is a future terrorist

Answers

Answer:

1.236 × 10^(-3)

Step-by-step explanation:

Let A be the event that the person is a future terrorist

Let B the event that the person is identified as a terrorist

We are told that there are 1,000 future terrorists in a population of 400 million. Thus, the Probability that the person is a terrorist is;

P(A) = 1000/400000000

P(A) = 0.0000025

P(A') = 1 - P(A)

P(A') = 1 - 0.0000025

P(A') = 0.9999975

We are told that the system has a 99% chance of correctly identifying a future terrorist. Thus; P(B|A) = 0.99

Thus, P(B'|A) = 1 - P(B|A)

P(B'|A) = 1 - 0.99

P(B'|A) = 0.01

We are told that there is a 99.8% chance of correctly identifying someone who is not a future terrorist. Thus; P(B'|A') = 0.998

Hence: P(B|A') = 1 - P(B'|A')

P(B|A') = 1 - 0.998

P(B|A') = 0.002

We want to find the probability that someone who is identified as a terrorist, is actually a future terrorist. This is represented by: P(A|B)

We can find it from bayes theorem as follows;

P(A|B) = [P(B|A) × P(A)]/[(P(B|A) × P(A)) + (P(B|A') × P(A')]

Plugging in the relevant values;

P(A|B) = [0.99 × 0.0000025]/[(0.99 × 0.0000025) + (0.002 × 0.9999975)]

P(A|B) = 0.00123597357 = 1.236 × 10^(-3)

Which statement best describes the meaning of one of the bars in the histogram? O 110 snacks have between 100 and 120 mg of sugar O 110 snacks have 7 mg of sugar. O 7 snacks have about 110 mg of sugar. O The largest number of snacks have 12 mg of sugar

Answers

The correct answer is option A. 110 snacks have between 100 and 120 mg of sugar.

A bar in a histogram represents a range of values and the height of the bar represents the frequency of the values in that range. In this case, the bar represents the range of values between 100 and 120 mg of sugar and the height of the bar represents the frequency of snacks with that amount of sugar. So, the statement that best describes the meaning of one of the bars in the histogram is: 110 snacks have between 100 and 120 mg of sugar.

In summary, the bar in the histogram represents a range of values and the height of the bar represents the frequency of the values in that range. In this case, the bar represents the range of values between 100 and 120 mg of sugar and the height of the bar represents the frequency of snacks with that amount of sugar.

How to find the area of a composite figure?

The composite figure consist of a rectangle and two semi circles. Therefore, the area of the composite figure is the sum of the area of the individua shapes.

Hence,

area of the composite figure = area of the rectangle + 2(area of semi circle)

Therefore,

area of the composite figure = 9 × 8 + 2(1 / 2 πr²)

area of the composite figure = 72 + πr²

From my point of view, if there are no other alternatives, and if it is possible that this will contribute to science, animals may be used for experimental research.Although the animal rights activists claim that people and animals are equal and thus they should be treated equally, I think that people and animals cannot be seen equal, and therefore the death of an animal cannot be the same thing as the death of a person. For that reason, causing animals to die for science, for the sake of saving human lives, may be considered ethical to some extent if it will contribute to the advancement of science and will be to the benefit of humanity in general.Furthermore, animal rights supporters label scientists as cruel for causing animals to die in medical experiments, while they do not oppose the people, mostly farmers, who kill animals for food, even though they know that 99% of animals deaths is caused by farmers while only a small percentage, i.e. 1% is caused by scientists. The underlying reason for that is they find scientists easier to attack and cannot deal with farmers who are organized and strong.Another basic argument of animal rights defenders is that people and animals are different genetically and therefore it is useless to use animals in experiments to see the effects of some substances on people. They claim that it will make no good to use animals in experiments because they are too different to be compared to people. Some of them even assert that it is better to use people directly as they think that the results of experiments on animals cannot be valid and reliable as long as the same observation has not been done on man also. However, these people cannot foresee the disastrous results of such a practice. Many people are likely to die until a healthy result is obtained.People and animals may not be the same, but to some degree there are similarities which can at least give scientists an idea about their experiments. From this point of view, scientists are right to use animal models to provide themselves with information about what is happening at level of detail that could not be achieved in humans. Although there might have been some incidents when animal testing did not prove to be useful and some effects of some drugs observed on animals could not be observed on people, there are also a lot of examples that show that using animals resulted in significant developments and helped to cure some serious illnesses.On the other hand, there may be alternative methods that should be used instead of animal experimentation. Then, of course, it is cruel and unethical to use animals. For example, in some experiments in-vitro methods can be used as an alternative to using live animals. In such occasions, it is certainly much better and right to employ these alternatives.All in all, it can be said that using animals for medical research is ethical a long as it contributes to scientific development and helps scientists find ways to improve human health. And this practice is only acceptable on the condition that necessary pains are taken and animals are treated humanely.
