The degree of freedom, df value for the chi-square statistic is 3.

In this question,

The chi-square goodness of fit test evaluates whether proportions of categorical or discrete outcomes in a sample follow a population distribution with hypothesized proportions. As a hypothesis test, the chi-square goodness of fit test allows you to use your sample to draw conclusions about an entire population.

Here,

Sample, n = 100

Number of categories, the sample is divided = 4

df is the degrees of freedom.

If there is a K category in the dataset and we want to apply chi-square goodness of fit test. Then, their degree of freedom df will be of k-1.

Thus, degree of freedom, df = k - 1

⇒ df = 4 - 1

⇒ df = 3

Hence we can conclude that the degree of freedom, df value for the chi-square statistic is 3.

The answer would be D..

Step-by-step explanation:

gallons to quarts have the ratio 1:4.

there are 4 quarts in a gallon (hence the name of quarts by the way).

so, the question is really, which order pair have also a 1:4 ratio between x and y ?

(1, 4)

(2, 8)

(3, 12)

the (4, 1) would represent a 4:1 ratio.

and as you know, 4/1 is different to 1/4.

a ratio is nothing else than a fraction. just the "whole" is different.

the pure fraction 1/4 means that the whole is 4/4, has 4 times 1/4.

a ratio 1:4 (you can also write as 1/4) means that the whole has 5 (1+4) parts.

other than that they are compared and calculated with the same way as normal fractions.

Step-by-step explanation:

The volume of the square pyramid in terms of x is (1/3) * x^4.

The volume V of a square pyramid can be calculated using the formula:

V = (1/3) * Base Area * Height

In this case, the base of the pyramid is a square with side length x, so the base area is given by:

Base Area = x^2

The height of the pyramid is given as x^2, so substituting these values into the volume formula, we have:

V = (1/3) * x^2 * x^2

Simplifying, we get:

V = (1/3) * x^4

Therefore, the volume of the square pyramid in terms of x is (1/3) * x^4.

First, we must determine b using slope-intercept form*, the given point, and the given slope.

\(-4 = -\frac{1}{3}(-9) + b\\\\-4 = -3 + b\\\\-1 = b\)

Second, we need to set up the equation of the line in slope-intercept form.

\(y = -\frac{1}{3}x - 1\)

Third, we convert the above equation to STANDARD FORM**.

\(y = -\frac{1}{3}x - 1\\\\\frac{1}{3}x + y = -1\)

We now have our equation: \(\frac{1}{3}x - y = -1\)

*Slope-intercept form: y = mx + b

**Standard form: ax + by = c

Answer: Given two points on a line, we can write an equation for that line by finding the slope between those points, then solving for the y-intercept in the slope-intercept equation y=mx+b.

This lane symbol is used for marking the beginning and ending of a left turn to the drivers.

What are lane symbols?

A permitted lane usage is denoted by a lane symbol. For example, a lane marked with a diamond is one that is designated for high-occupancy cars.  A lane symbol of a bicycle marks that the lane is designated for cyclists. At crossings, arrows indicate movements that are necessary or allowed. The user of the roadway must yield when there is a row of solid triangles. Likewise, two large curved arrows facing each other on a lane in the middle of a two way road with dashed lines on either sides indicate the beginning and ending of a left turn.

A Lane symbol or marking are also utilized to warn drivers of potentially dangerous situations that may be coming up. For instance, a triangle with no filling indicates a yield ahead. A speed hump is indicated by a succession of lines across a lane that get bigger and wider.

True. The is subset() method is used to check if all elements of set1 are present in set2, which means set1 is a subset of set2 if the is subset() method returns true.

True. The "is subset()" method can be used to determine whether set1 is a subset of set2. If all elements of set 1 are present in set 2, then set 1 is considered a subset of set 2. The method returns `True` if set1 is a subset of set2 and `False` otherwise.
In mathematics, if all the elements of A are also elements of B, then the set A is one of the set B; then B is a superset of A. A and B may be equal; if they are not, A is a necessary condition of B. A relationship in which one group is one of the other is called existence (or sometimes existence). A is part of B, it can also indicate that B contains (or contains) A, or that A contains (or contains) B. A k-subset is a subset with k elements.

A linked subset defines the partial order of a set. In fact, intersection and union give intersection and intersection, with subsets of the given set being Boolean algebra in the relationship, and the link itself is a Boolean coverage relationship.
Example usage:
```python
set1 = {1, 2, 3}

Given:

Price of  gold in 2001 = (0.5x+300)

Its price tripled in 2008 and then doubled in 2011. In 2016, its price dropped to \(\dfrac{2}{3}\) of the price in 2011.

To find:

An expression for the price of gold per ounce in 2016.

Solution:

We have,

Price of  gold in 2001 \(= (0.5x+300)\)

Its price tripled in 2008.

Price of  gold in 2008 \(= 3(0.5x+300)\)

Then doubled in 2011.

Price of  gold in 2011 \(= 2\times 3(0.5x+300)\)

In 2016, its price dropped to \(\dfrac{2}{3}\) of the price in 2011.

Price of  gold in 2016 \(=\dfrac{2}{3}\times 2\times 3(0.5x+300)\)

                                    \(=2\times 2(0.5x+300)\)

                                    \(=4(0.5x+300)\)

                                    \(=4(0.5x)+4(300)\)

                                    \(=2x+1200\)

Therefore, the required expression for the price of gold per ounce is (2x+1200).

Answer:

A is 6

B is 37.5

C is 6

Step-by-step explanation:

The value of "w" in the algebraic equation

4w = 96 which makes it true is equal to 24.

An algebraic equation is a mathematical statement that contains two equated algebraic expressions.

We shall evaluate for the value of w in the algebraic equation 4w = 96 as follows:

The coefficient of w is 4 and can be removed to allow w stand alone by dividing both sides of the equation by 4

4w/4 = 96/4

w = 96/4

96 = 24 × 4, so 4 can cancel out and we have;

w = 24

Therefore, 24 is the value of w in the algebraic equation 4w = 96 that makes it true.

The periodic payment required to amortize a loan of $80,000 over 12 years with an interest rate of 3.5% compounded semi-annually is approximately $796.25.

To find the periodic payment required to amortize a loan, we can use the formula:

R = (P * r/100) / (1 - (1 + r/100)^(-n))

Where R is the periodic payment, P is the loan amount, r is the annual interest rate, and n is the total number of periods.

In this case, the loan amount is $80,000, the annual interest rate is 3.5%, and the loan needs to be amortized over 12 years with compounding done semi-annually (m = 2).

Substituting these values into the formula, we get:

R = (80,000 * 3.5/100) / (1 - (1 + 3.5/100)^(-12*2))

Calculating this expression, we find that the periodic payment required to amortize the loan is approximately $796.25.

Therefore, the periodic payment required to amortize a loan of $80,000 over 12 years with an interest rate of 3.5% compounded semi-annually is approximately $796.25.

The percent of change from 12 to 6 is -50%. This indicates a decrease of 50%.

A measure of the relative difference between two values is the percent of change, also known as percentage change or percent change.

It is frequently used to convey how much a quantity has changed over time, as well as how much it has risen or fallen relative to its starting point.

To find the percent of change between two values, we use the formula:

Percent change = [(New value - Old value) / Old value] x 100%

In this case, the old value is 12 and the new value is 6.

Adding these values to the formula yields the following results:

percent change = [(6 - 12) / 12] x 100%

percent change = (-6 / 12) x 100%

percent change = -0.5 x 100%
