A function can have zero to many parameters, and it can return only one (option c).

In mathematics, a function is a rule that maps each element from one set, called the domain, to a unique element in another set, called the range.

The number of parameters a function can take determines the number of arguments required to call the function.

For instance, a function f(x) takes one parameter, and it requires one argument to be called.

On the other hand, a function g(x,y,z) takes three parameters, and it requires three arguments to be called. However, a function h() takes no parameters and does not require any argument to be called.

Hence the correct option is (c).

We are 92% confident that the true population proportion of Americans who support legalizing marijuana is between 0.61 and 0.65. Therefore, option B. is correct.

To construct a 92% confidence interval for the true population proportion of Americans who support legalizing marijuana, we need to follow these steps:

1. Calculate the sample proportion (p):
p = (number of people in favor) / (total number surveyed)

= 1147 / 1821 ≈ 0.6298

2. Determine the critical value (z*) for a 92% confidence interval using a standard normal (z) table or calculator. In this case, z* ≈ 1.75.

3. Calculate the margin of error (ME):
ME \(=z^{*} \times \sqrt{\frac{p \times(1-p)}{n}}\)

≈ \(1.75 \times \sqrt{[(0.6298 \times (1 - 0.6298)) / 1821]}\) ≈ 0.0198

4. Construct the confidence interval:
Lower bound = p - ME ≈ 0.6298 - 0.0198 ≈ 0.61
Upper bound = p + ME ≈ 0.6298 + 0.0198 ≈ 0.65

So, the 92% confidence interval for the true population proportion of Americans who support legalizing marijuana is between 0.61 and 0.65 (rounded to 2 decimal places).

Answer: B. We are 92% confident that the true population proportion of Americans who support legalizing marijuana is between .61 and .65.

The null distribution in this case is a normal distribution with the same mean as the sample mean (2.515) and the same standard deviation as the sample standard deviation (1.630).

To identify the null distribution in this scenario, we need to determine the appropriate distribution that represents the population from which the soil specimen data was sampled.

In this case, we are given a sample of 30 soil specimens, and the variable of interest is the percentage of organic matter in the soil. The sample mean is 2.515 and the sample standard deviation is 1.630.

Based on the given information, we can make use of the Central Limit Theorem (CLT). The CLT states that for a large enough sample size, the sampling distribution of the sample mean will approach a normal distribution, regardless of the shape of the population distribution.

Since the sample size of 30 is reasonably large, we can assume that the sample mean of the percentage of organic matter in the soil follows a normal distribution.

Therefore, the null distribution in this case is a normal distribution with the same mean as the sample mean (2.515) and the same standard deviation as the sample standard deviation (1.630).

To find the result of 2A - 3BC, we first need to perform matrix multiplication. Let's calculate each component of the resulting matrix step by step.

First, we calculate 2A by multiplying each element of matrix A by 2.

2A = 2 * |1 2 3| = |2 4 6|

Answer:

173.2 cm²

Step-by-step explanation:

Use the equilateral triangle area formula, A = \(\frac{\sqrt{3}}{4}\)a²

Plug in the side length and solve:

A = \(\frac{\sqrt{3}}{4}\)a²

A = \(\frac{\sqrt{3}}{4}\)(20)²

A = \(\frac{\sqrt{3}}{4}\)(400)

A = 173.2

So, the area of the triangle is approximately 173.2 cm²

Hence the average rate of change, in simplest form is -10 .

What is average rate of change?

Using the coordinate points from the table  ( 4,53) ( 8, 13 )

Substitute the coordinate into the expression

Average rate of change  = y₂ - y₁/x₂ - x₁

The width of the enclosure is 7 feet.

The formula for the perimeter of a rectangle is P = 2L + 2W, where L is the length and W is the width. Since the length of the enclosure is given as 11 feet and the total length of fencing used is 36 feet,

we can set up an equation:

P = 2L + 2W = 36

Substituting the given value of L, we have:

2(11) + 2W = 36

Simplifying the left side, we get:

22 + 2W = 36

Subtracting 22 from both sides, we get:

2W = 14

Dividing both sides by 2, we get:

W = 7

There are two stiff transforms to use:

The fact that the real domain is the domain of quadratic functions makes it possible to identify the solution set.

Thus, we must decide which rigid transformations to apply to f(x) in order to produce g(x). Rigid transformations are transformations applied to geometric loci in the field of Euclidean geometry so that Euclidean distances within the latter are conserved (x).

Following thorough consideration, we come to the conclusion that the two stiff transformations listed below must be used:

Vertical translation 7 units to the plus side.

If the shape is made up of one half-circle attached to an equilateral triangle with side lengths 20 inches then, the perimeter of the shape is 91.4 inches.

To find the perimeter of the shape, we need to know the length of the curved boundary (the circumference of the half-circle) and the length of the straight boundary (the perimeter of the equilateral triangle).

The radius of the half-circle is half the length of the side of the equilateral triangle, which is 10 inches. Therefore, the circumference of the half-circle is:

C = πr = π(10) = 31.4 inches.

The perimeter of the equilateral triangle is 3 times the length of one side, which is 20 inches. Therefore, the perimeter of the triangle is:

P = 3s = 3(20) = 60 inches

Finally, the perimeter of the entire shape is the sum of the lengths of the curved and straight boundaries:

Perimeter = C + P = 31.4 + 60 = 91.4 inches.

In the given stem-and-leaf plot, we can conclude that there are at least 5 outliers

The number of outliers in the given stem-and-leaf plot can be determined by identifying values that are significantly higher or lower than the majority of the data.

To find the number of outliers in the stem-and-leaf plot, we need to analyze the data distribution and identify values that deviate significantly from the rest of the scores.

Looking at the stem-and-leaf plot, we observe that the majority of the scores are concentrated between 20 and 90. The numbers 2, 3, 4, 5, 6, 7, 8, 9, and 10 represent the tens digit of the scores, while the leaves represent the ones digit.

Upon examining the plot, we notice that there are a few values that stand out from the rest. These values are 00, 01677, 6899, 233569999, and 01268. Outliers are typically defined as values that fall outside the "typical" range of the data, and these values appear to deviate significantly from the majority of the scores.

To determine the exact number of outliers, we need to apply specific criteria. One common method is to use the 1.5 × IQR (interquartile range) rule. The IQR is calculated as the difference between the third quartile (Q3) and the first quartile (Q1) of the data. Any values below Q1 - 1.5 × IQR or above Q3 + 1.5 × IQR are considered outliers.

In this case, we don't have the exact raw data to calculate the quartiles and IQR. However, based on visual inspection of the stem-and-leaf plot, we can still identify the values mentioned earlier as outliers due to their significant deviation from the majority of the scores.

Therefore, in the given stem-and-leaf plot, we can conclude that there are at least 5 outliers

Actually, not all of the options are correct. The statement "Most economic data can be modeled as a higher-order ARMA(p, q) model" is not entirely accurate. While it is true that many economic time series exhibit some degree of autocorrelation and can be modeled using ARMA models, not all economic data can be accurately represented by these models.

In fact, some time series may require more complex models such as state-space models, VAR models, or GARCH models to capture the underlying dynamics.

Regarding the other statements:

Spikes in the autocorrelation function do indicate autoregressive terms, as autocorrelation measures the correlation between a time series and its past values.

Spikes in the partial-autocorrelation function do indicate moving-average terms, as partial-autocorrelation measures the correlation between a time series and its past values, controlling for the effects of intermediate lags.

For an ARMA(p, q) model, the autocorrelation function should show an abrupt stop at lag p, indicating the presence of p autoregressive terms. The partial-autocorrelation function should show an abrupt stop at lag q, indicating the presence of q moving-average terms.
