The only combination you will not find in a valid deductive argument is "false premises and a true conclusion."

A deductive argument is considered valid when the conclusion logically follows from the premises. In other words, if the premises are true, the conclusion must also be true. Therefore, in a valid deductive argument, the premises and conclusion must have a consistent truth value.

Let's examine the given answer choices:

1. True premises and a false conclusion: This combination would result in an invalid deductive argument because the conclusion contradicts the truth of the premises. For example:

Premise 1: All mammals are warm-blooded.

Premise 2: Elephants are mammals.

Conclusion: Elephants are cold-blooded.

2. True premises and a true conclusion: This combination represents a valid deductive argument. If the premises are true and the conclusion logically follows, the argument is valid.

3. False premises and a false conclusion: This combination may or may not represent a valid deductive argument. Although the premises and conclusion have the same truth value, it does not necessarily mean that the argument is valid. It is possible for a deductive argument with false premises and a false conclusion to be valid, as long as the reasoning is sound.

4. False premises and a true conclusion: This combination represents an invalid deductive argument. The truth of the conclusion cannot be guaranteed if the premises are false. Therefore, this combination is the one you will not find in a valid deductive argument.

In a valid deductive argument, you will not find the combination of false premises and a true conclusion. This combination would render the argument invalid because the conclusion would not be guaranteed to follow logically from the false premises.

The image attached shows a linear equation passes in the following points:  (0,5) and (-5/3,0).

An equation can be represented by a linear function. The standard form for the linear equation is: y= mx+b , for example, y=10x+5. Where:

m= the slope. It can be calculated for Δy/Δx.

b= the constant term that represents the y-intercept.

For the given example: m=10 and b=5.

A linear function presents an x-intercept and a y-intercept. The x-intercept represents the point (x,0) that the line crosses the x-axis, on the other hand, the y-intercept represents the point that crosses the y-axis (0,y).

The question gives: 3x-y= -5.

For finding the x-intercept, you need to consider y=0, then:

3x-y= -5

3x-0= -5

3x=- 5

x=-5/3

For finding the y-intercept, you need to consider x=0, then:

3x-y= -5

3*0-y= -5

-y= -5

y=5

Now, plot a line that passes for the points (0,5) and (-5/3,0)

In this case, 114.098 rounds up to 115 when rounded to the nearest whole number. Thus, James needs 115 one-gallon jugs to hold all of the soda.

To find the total volume of soda in gallons, we first need to convert the total volume of soda from liters to gallons. We can use the conversion factor 1 gal = 3.785 L.

So, we start by multiplying the number of 2-liter bottles by 2 to get the total volume of soda in liters:

216 x 2L = 432 L

Then, we can convert this value to gallons by dividing by the conversion factor:

432 L / 3.785 L/gal = 114.098 gal

Since we can't have a fraction of a jug, we need to round up to the nearest whole number of jugs. In this case, 114.098 rounds up to 115 when rounded to the nearest whole number.

Therefore, James needs 115 one-gallon jugs to hold all of the soda.

Answer: Choice F. Hyperbola opening up and down.

======================================================

Explanation:

The subtraction symbol between the two fractions indicates right off the bat that we're dealing with a hyperbola. The question now is "How does it open? Does it open up/down? Or does it open left/right?"

To answer this new question, we just need to look at which fraction is negative. The fraction with x in it is negative, so that means the y fraction is positive. The y fraction being positive is the indication of the hyperbola opening up/down.

Answer:

The initial value is $5.00

Step-by-step explanation:

The question required us to find the y-intercept or c in the equation of the straight line.

We are given 4 different points on the graph and we are also told the hourly fee. As we know that the graph has total hours on x axis and total cost on y axis, we can calculate the gradient or slope of the graph.

m = (23 - 18.5) / (4 - 3)

m = 4.5

Taking point (3,18.5) for calculating c or y intercept from the equation of straight line that is,

y = m (x) + c

18.5 = 4.5 (3) + c

18.5 = 13.5 + c

18.5 - 13.5 = c

c = 5

So the admission fee is $5.

Therefore, after using three-fourths of the rice in the box, 4 and 1/4 cups of rice remained.

To find the number of cups of rice that remained in the box, we need to calculate three-fourths (3/4) of the total amount of rice in the box.

The total amount of rice in the box is given as five and two-thirds cups. To work with a fraction, we can convert the mixed number to an improper fraction:

5 and 2/3 = (5 * 3 + 2) / 3 = 17/3 cups

Now, we can find three-fourths (3/4) of 17/3:

(3/4) * (17/3) = (3 * 17) / (4 * 3) = 51/12 = 4 and 3/12 = 4 and 1/4 cups

Therefore, after using three-fourths of the rice in the box, 4 and 1/4 cups of rice remained.

The pros and cons of Kernel Density Estimation (KDE) over histogram has been compared and advantage and disadvantage to each has been given.

Kernel Density Estimation (KDE) and histograms are both methods used for visualizing and estimating probability density functions.

KDE offers advantages such as its ability to capture smooth and continuous distributions, while histograms have benefits like simplicity and ease of interpretation.

However, KDE can be computationally intensive, and histograms may suffer from binning bias.

Kernel Density Estimation (KDE) is a non-parametric method used to estimate the probability density function of a random variable. It offers several advantages over histograms.

Firstly, KDE is able to capture smooth and continuous distributions, providing a more accurate representation of the underlying data.

Additionally, KDE does not rely on binning, allowing for a more precise estimation of the density at any point.

Furthermore, KDE can handle missing or irregularly spaced data.

On the other hand, histograms have their own advantages. They are simple and intuitive, making them easy to understand and interpret.

Histograms also tend to be less computationally intensive compared to KDE, making them suitable for large datasets.

Moreover, histograms can reveal the presence of outliers or gaps in the data due to the discrete nature of the bins.

However, there are also drawbacks to consider. KDE can be computationally intensive, especially for large datasets, requiring more processing power and time compared to histograms.

This can be a limitation when dealing with real-time or interactive applications. In contrast, histograms suffer from binning bias, where the choice of bin size can affect the visual representation and interpretation of the data.

Selecting an inappropriate bin size can lead to either over-smoothing or over-detailing the data distribution.

In summary, KDE offers advantages in capturing smooth distributions and avoiding binning bias, but it may be computationally intensive.

Histograms, on the other hand, are simple and computationally efficient but can suffer from binning bias.

The choice between KDE and histograms depends on the specific characteristics of the data and the objectives of the analysis.
