what type of statistical procedure should you use if your dependent variable is measured on a ratio scale? select one: chi-square test for goodness of fit chi-square test for independence non-parametric test parametric test

Answers

Answer 1

If your dependent variable is measured on a ratio scale, you should use statistical procedure of parametric test. The correct answer is D).

Parametric tests are statistical tests that assume a normal distribution of data and require interval or ratio scale measurements. Examples of parametric tests include t-tests, ANOVA, and linear regression. Non-parametric tests, on the other hand, do not assume a normal distribution of data and can be used for nominal, ordinal, interval, or ratio scale measurements.

Examples of non-parametric tests include the chi-square test for goodness of fit and the chi-square test for independence. However, these tests are not appropriate for ratio scale measurements, so you should use a parametric test. So, the correct option is D).

Answer:

The numerator is x²+6x+5.

We need to first factorise the expression

The coefficient of x² is 1, and the constant term of the quadratic expression is 5.

the product of coefficient of x² and constant term=5

∴ we break the middle term, 6x, such that,  the product of the coeffcients of  the two terms is 5, while their sum is 6

∴ 6x=5x+x

Now, rewriting the expression,

x²+5x+x+5

Taking x as common factor in x² and 5x,

x(x+5)+x+5

Again, taking x+5 as the common factor,

(x+5)(x+1)

Now, replacing x²+6x+5 with (x+5)(x+6) in the expression,

(x+5)(x+1)/(x+2)

Hence the value of the expression is (x+5)(x+1)/(x+2)

one group of 3 adults and 5 childern paid a total of $32.50 for admisson.another group of 4 adults and 4 children paid $34.00 for admisson. what is the cost of admisson for one child

Answers

The cost of admission for one child is $5.60.

To find the cost of cost of admisson for one child, we can set up a system of linear equations using the given information.
Let A represent the cost of admission for one adult and C represent the cost of admission for one child.

We can write two equations based on the information given:
3A + 5C = $32.50 (for the first group)---------(1)
4A + 4C = $34.00 (for the second group)---------(2)
We can solve these equations step-by-step to find the value of C:

Multiply equation (2) by -1 so that we can eliminate A when adding both equations:
-4A - 4C = -$34.00

Add equations (1) and the modified equation (2) to eliminate A:
(3A + 5C) + (-4A - 4C) = $32.50 + (-$34.00)
-A + C = -$1.50

Multiply the whole equation by -1 to get rid of the negative sign:
A - C = $1.50 ---------(3)

Add equation (2) to the equation we got in step 3 to eliminate C:
(4A + 4C) + (A - C) = $34.00 + $1.50
5A + 3C = $35.50

Divide the equation by 5 to find the value of A:
A = $7.10

Substitute the value of A back into the equation 3:
$7.10 - C = $1.50

Solve for C:
C = $7.10 - $1.50
C = $5.60

what when two variables are related such that people with high scores on one tend to have high scores on the other and people with low scores on one ten to have low scores on the other.(s) of variables are appropriate for a correlation?

Answers

When two variables are related in such a way that people with high scores on one variable tend to have high scores on the other, and people with low scores on one variable tend to have low scores on the other, it is called a positive correlation. This type of relationship between variables is appropriate for a correlation analysis.



A correlation is a statistical technique used to measure the strength and direction of the association between two variables. The most common correlation coefficient is the Pearson's correlation coefficient, which ranges from -1 to 1. A positive correlation indicates a direct relationship between the variables, while a negative correlation indicates an inverse relationship. A correlation close to 0 suggests no relationship between the variables.

To conduct a correlation analysis, the variables should be continuous or ordinal, which means that they can be measured on a scale with meaningful intervals. Examples of continuous variables include age, height, and weight, while ordinal variables could include rankings, such as class rank or satisfaction levels.

Here's a step-by-step explanation for conducting a correlation analysis:

1. Identify the two variables of interest, ensuring they are continuous or ordinal.
2. Collect the data for each variable from a sample of individuals or observations.
3. Calculate the mean and standard deviation for each variable.
4. Compute the covariance between the two variables, which measures the degree to which they change together.
5. Normalize the covariance by dividing it by the product of the standard deviations of the two variables. This produces the correlation coefficient, which represents the strength and direction of the relationship between the variables.

In summary, a correlation analysis is appropriate when examining the relationship between two continuous or ordinal variables, such as in the case of a positive correlation where high scores on one variable are associated with high scores on the other, and low scores on one variable are associated with low scores on the other.

andy's lawn has twice as much area as beth's lawn and three times as much area as carlos' lawn. carlos' lawn mower cuts half as fast as beth's mower and one third as fast as andy's mower. if they all start to mow their lawns at the same time, who will finish first?

Answers

In the given word problem, they all start to mow their lawns at the same time, Beth will finish first.

Let's assume that Beth's lawn has an area of x, so Andy's lawn has an area of 2x, and Carlos' lawn has an area of (1/3) × 2x = (2/3)x. Let's also assume that Beth's lawn mower can mow at a rate of 1 unit of area per hour, so Carlos' mower can mow at a rate of 1/2 = 0.5 units of area per hour, and Andy's mower can mow at a rate of 1/3 units of area per hour.  We can calculate the time it will take each person to mow their lawn by using the formula:

Time = Area / Rate.

Beth's time = x / 1

                   = x hours

Carlos' time = (2/3)x / 0.5

                    = (4/3)x hours

Andy's time = 2x / (1/3)

                    = 6x hours

According to these facts, it is quite clear that Beth would finish first followed by Carlos and Andy would finish last.

A researcger estimates that a fossil is 3200 years old.Using carbon-14 dating,a procedure used to determine the age of an object,the researcher discovers that the fossil is 3600 years old.
a.Find the percent error
b.what other estimates gives the same percent error?Explain

Answers

The percentage error between the estimated age and the carbon-14 dating age of the fossil is 12.5% and an estimated age of approximately 2978 years would give the same percent error of 12.5%.

What is the definition of percentage?

Percentage is a way of expressing a fraction or proportion as a part of 100. It is denoted by the symbol "%". The term "percent" means "per hundred". For example, if 50% of a group of people are men, it means that 50 out of every 100 people in the group are men.

Now,

a). To find the percent error between the estimated age and the carbon-14 dating age of the fossil, we can use the formula:

percent error = |(estimated age - carbon-14 dating age) / estimated age| x 100%

Substituting the given values, we get:

percent error = |(3200 - 3600) / 3200| x 100%

= |-400 / 3200| x 100%

= 12.5%

Therefore, the percent error between the estimated age and the carbon-14 dating age of the fossil is 12.5%.

b). To find other estimates that give the same percent error, we can use the formula:

percent error = |(estimated age - carbon-14 dating age) / estimated age| x 100%

If we let x be the estimated age that gives the same percent error, then we can write:

12.5% = |(x - 3600) / x| x 100%

Simplifying, we get:

0.125 = |(x - 3600) / x|

Taking the positive square root of both sides (since percent error cannot be negative), we get:

√0.125 = (x - 3600) / x

Simplifying, we get:

x = 3600 / (1 - √0.125)

x ≈ 2978

Therefore, an estimated age of approximately 2978 years would give the same percent error of 12.5% as the original estimated age of 3200 years. This means that if the fossil were actually 2978 years old, the carbon-14 dating would have given an age estimate of approximately 3299 years, which is 12.5% higher than the true age.

As elevation increases, the atmospheric air pressure decreases. The air pressure P in pascals given the altitude a in meters is a = 15,500 (5 - log₁0 P). What is the air pressure at the peak of Mount Marcy, which has an elevation of 1629 meters? Round your answer to the nearest whole pascal.​

Answers

The air pressure at the peak of Mount Marcy is approximately 164.17 pascals.

What is air pressure?

Air pressure, also known as atmospheric pressure, is the force exerted by the weight of the Earth's atmosphere on any given surface. It is the weight of the column of air that extends from the Earth's surface up to the top of the atmosphere.

What is Pascal?

The Pascal (symbol: Pa) is the SI (International System of Units) unit of pressure, named after the French mathematician and physicist Blaise Pascal. One pascal is defined as the pressure exerted by the force of one Newton on an area of one square meter. In other words, 1 Pa = 1 N/m².

According to the given information

We are given the formula that relates the altitude (a) and the atmospheric air pressure (P):

a = 15,500 (5 - log₁0 P)

We are also given that the altitude at the peak of Mount Marcy is 1629 meters. We can use this information to find the atmospheric air pressure at the peak of Mount Marcy by plugging in a = 1629 and solving for P:

1629 = 15,500 (5 - log₁0 P)

Dividing both sides by 15,500, we get:

(5 - log₁0 P) = 1629 / 15,500

Subtracting 5 from both sides, we get:

-log₁0 P = (1629 / 15,500) - 5

Simplifying the right-hand side, we get:

-log₁0 P = -1.5454

Taking the inverse logarithm (base 10) of both sides, we get:

P = 10⁻¹.⁵⁴⁵⁴

Using a calculator, we can evaluate this expression to get:

P ≈ 164.17 pascals

roughly, what do you expect the ratio of the time taken to compute lu factorization vs. back/forward substitution to be?

Answers

The ratio of the time taken to compute LU factorization vs. back/forward substitution depends on several factors such as the size and sparsity of the matrix, the specific implementation of the algorithms, and the hardware used to perform the computations.

However, in general, LU factorization takes more time than back/forward substitution. This is because LU factorization involves decomposing the original matrix into two matrices, L and U, which requires more computations than simply solving the system of equations using back/forward substitution once the L and U matrices are available.

As a rough estimate, the time taken for LU factorization can be several times larger than the time taken for back/forward substitution, especially for large and dense matrices.

However, the exact ratio can vary widely depending on the specific factors mentioned above.

In the above mentioned similar triangles the length of DE is 5.25 cm.

What is triangle?

A triangle is a three-sided polygon with three vertices. The triangle's internal angle, which is 180 degrees, is constructed.

Since triangles ABC and ADE are similar, their corresponding sides are proportional. We can use this fact to set up a proportion:

AB / AD = BC / DE

Substituting the given values, we get:

8 / AD = 6 / DE

Multiplying both sides by DE, we get:

8DE / AD = 6

Dividing both sides by 8/AD, we get:

DE = (6/8)AD

We need to find AD to solve for DE. To do this, we can use the fact that BD is an altitude of triangle ABC and triangle ADE is similar to triangle ABC. Therefore, triangle ABD is also similar to triangle ABC, and we can set up another proportion:

BD / AB = AD / AC

Substituting the given values, we get:

4 / 8 = AD / (8 + 6)

Simplifying, we get:

1/2 = AD / 14

Multiplying both sides by 14, we get:

AD = 7

Substituting this value back into the first equation, we get:

DE = (6/8)AD = (6/8)7 = 21/4 = 5.25

Therefore, the length of DE is 5.25 cm.

A linear equation is an equation that represents a straight line on a graph. It is an algebraic equation in which each term is either a constant or the product of a constant and a single variable.

Both Kwasi and Lola wrote true equations.

Kwasi's equation, b+132=180, is true because in a triangle, the sum of the interior angles is always 180 degrees. The angle measures opposite to sides b and c are a and f, respectively, so b+a+f=180. Since a+f=48+132=180- b, we can substitute and get b+132=180, which is true.

Similarly, Lola's equation, 132+f=180, is also true because the sum of the angles in a triangle is always 180 degrees, and angle A has a measure of 48 degrees,

you organize a chess tournament and 15 people sign up. you would like each person to play against 5 others to decide who makes the elimination round. is this possible? explain why or why not

Answers

It is not possible to have each of the 15 participants play against exactly 5 others in your chess tournament.

Here's why:
1. In a tournament where each person plays against 5 others, the total number of matches played can be calculated using the combination formula: C(n, k) = n! / (k!(n-k)!),

where n is the number of participants and k is the number of opponents each player faces.

In this case, n = 15 and k = 5.
2. Applying the formula, we get C(15, 5) = 15! / (5!(15-5)!) = 15! / (5!10!) = 3,003 matches in total.

However, since each match involves two players, the actual number of matches played is 3,003 / 2 = 1,501.5.

This is not a whole number, so it is impossible to have exactly 5 matches per player in this scenario.
3. To further confirm this, we can also analyze the problem using graph theory.

Each participant can be represented as a node in a graph, and a match between two participants can be represented as an edge connecting the corresponding nodes.
4. In this case, we want each node to have a degree of 5 (i.e., 5 edges connecting to it).

The Handshaking Lemma states that the sum of the degrees of all nodes in a graph is equal to twice the number of edges in the graph.

Thus, in our scenario, the sum of all degrees would be 15 * 5 = 75.

A problem-solving technique known as the unitary method is determining the value of only one unit and utilising that value to determine the value of another quantity which is either a multiple or indeed a fraction of the unit. It is frequently employed in maths, particularly in numeracy and algebra. In the unitary technique, a ratio or percentage is used to solve a problem where two quantities are related to one another by a constant number, that is, the value of one unit. This approach can be used to solve issues involving rates, costs, ratios, and other comparable quantities.

given

Let's start by calculating the price per load of the 5-pound package.

Cost per load is calculated as Box Cost / Number of Loads ($3.50 / 20 = $0.175).

Let's now calculate the price per load for the 15-pound box:

Cost each load is box price / the number of loads, which is $10.00 / (3 x 20) = $10.00 / 60 = $0.1667 per load.

to calculate the amount you will save per load if you purchase the 15-pound package.

Expense per load of a 5-pound box minus savings per load - The price per 15-pound box load.

Savings per load are equal to $0.175 - $0.1667, or $0.0083. (rounded to the nearest cent)

Hence, if you purchase the 15-pound box rather than the 5-pound box, you will save roughly $0.0083 every load.

The cost of oranges is $0.80 per pound, so the cost of (11.75 - x) pounds of oranges is 0.8(11.75 - x).

The total cost of the fruit purchase is $8.00, so we can write:

0.4x + 0.8(11.75 - x) = 8

Simplifying this equation:

0.4x + 9.4 - 0.8x = 8

-0.4x = -1.4

x = 3.5

Therefore, Ms. Wells bought 3.5 pounds of bananas.

So the answer is (B) 3.50 pounds.

Answers

Answer: 120 %

Step-by-step explanation:

part/whole = percent/100

Let x be the percentage we are trying to find, then we can write:

5.40/4.50 = x/100

To solve for x, we can cross-multiply:

4.50x = 5.40 * 100

Dividing both sides by 4.50, we get:

x = (5.40 * 100) / 4.50 = 120

Therefore, $5.40 is 120% of $4.50.

a computer is printing out subsets of a 6 element set (possibly including the empty set). (a) at least how many sets must be printed to be sure of having at least 2 identical subsets on the list?

Answers

To find the minimum number of subsets that must be printed to ensure at least two identical subsets on the list, we can use the concept of Pigeonhole Principle. At least 65 sets must be printed to be sure of having at least 2 identical subsets on the list.

1. First, we need to find the total number of possible subsets in a 6-element set. We use the formula 2^n, where n is the number of elements. In this case, n = 6.
2. Calculate the total number of subsets: 2^6 = 64.
3. According to the Pigeonhole Principle, if there are N pigeonholes (subsets) and more than N pigeons (printed subsets), at least one pigeonhole will have more than one pigeon.
4. To ensure that we have at least 2 identical subsets, we need to print one more subset than the total number of possible subsets: 64 + 1 = 65.

can there be a right triangle with sides of lengths 1, 2, and 3? why or why not? can you find a right triangle whose side lengths are consecutive natural numbers?

Answers

No, there cannot be a right triangle with sides of lengths 1, 2, and 3. This is because of the Pythagorean theorem.

The theorem states that in a right triangle, the square of the hypotenuse (the longest side) is equal to the sum of the squares of the other two sides. Mathematically, this can be written as:

[tex]c^2 = a^2 + b^2[/tex]

where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

If we substitute the values of 1, 2, and 3 for a, b, and c, respectively, we get:

[tex]3^2 = 1^2 + 2^2[/tex]

which simplifies to:

9 = 1 + 4

This is not true, so the sides 1, 2, and 3 do not form a right triangle.

However, there exist right triangles with consecutive natural numbers as their side lengths. One such example is the Pythagorean triple (3, 4, 5), where:

[tex]3^2 + 4^2 = 9 + 16 = 25 = 5^2[/tex]

This is a right triangle where the lengths of the sides are consecutive natural numbers. There are infinitely many such Pythagorean triples, and they can be generated using the formula:

[tex]a = 2mn, b = m^2 - n^2, c = m^2 + n^2[/tex]

where m and n are any two positive integers with m > n.

the statistic that half of all marriages end in divorce is an accurate depiction of the situation. question 12 options: true false

Answers

The actual divorce rate in the United States is around 39%, and it is important to consider the specific factors that contribute to divorce rates rather than relying on a generalization about marriage.

The statistic that half of all marriages end in divorce is not an accurate depiction of the situation.

The statement is false.The statement that half of all marriages end in divorce is a widely held belief that has been perpetuated by popular media, but it is not an accurate depiction of the situation.

The actual divorce rate in the United States has been declining since the 1980s and is currently around 39%.The misconception about the high divorce rate is due in part to the fact that many people get divorced more than once, inflating the overall divorce rate.

Additionally, certain demographics are more likely to get divorced than others, such as those who marry at a young age or those with lower levels of education. Therefore, it is important to consider the specific factors that contribute to divorce rates rather than relying on a generalization about marriage.In conclusion, the statement that half of all marriages end in divorce is false.
