The calculated area of one of its bases is 41 square units

From the question, we have the following parameters that can be used in our computation:

Volume = 164 cubic units

Height = 4 units

using the above as a guide, we have the following:

Base area = Volume / Height

substitute the known values in the above equation, so, we have the following representation

Base area = 164/ 4

Evaluate

Base area = 41

Hence, the area of one of its bases is 41 square units

Step-by-step explanation:

Hey there!

The equation of a st.line passing through points (4,5) and (8,9) is;

\((y - y1) = \frac{y2 - y1}{x2 - x1} (x - x1)\)

Put all values.

\((y - 5) = \frac{9 - 5}{8 - 4} (x - 4)\)

Simplify them to get equation.

\((y - 5) = \frac{4}{4} (x - 4)\)

\((y - 5) = 1(x - 4)\)

\((y - 5) = x - 4\)

\(x - y + 1 = 0\)

Therefore the required equation is: x - y + 1=0.

The probability that a selected individual's height will be less than 45 inches is approximately 0.0228.

We can use the normal distribution to find the probability that a selected individual's height will be less than 45 inches. We'll need to first calculate the z-score for a height of 45 inches, and then use a standard normal distribution table or calculator to find the corresponding probability.

The formula for calculating the z-score is:

z = (x - μ) / σ

Where x is the height we're interested in, μ is the population mean (given as 53 inches), and σ is the population standard deviation (given as 4 inches).

Plugging in the values, we get:

z = (45 - 53) / 4 = -2

Now, we can use a standard normal distribution table or calculator to find the probability of a z-score less than -2. Using a table, we find that the probability is approximately 0.0228.

When two angles in a plane share a vertex and a side but no common interior points, they are called adjacent angles

The terms adjacent, neighboring, contiguous, and juxtaposed all denote being close by. Although adjacent might indicate a touch or not, it is usually assumed that there is nothing of the same sort in between. a home with a garage close by. Adjoining clearly means coming together and touching at a certain location or line.

When two angles have a similar vertex and side, they are referred to as neighboring angles. The vertex of an angle is the point at which the rays that make up its sides come to a stop. When adjacent angles have the same vertex and side, they might be a complimentary angle or supplemental angle.

Thus, adjacent angles are two angles that lie in the same plane and have a common vertex and a common side but have no common interior points.

Step-by-step explanation:

You may use this formula to find the slope of a line going through points \((x_1,y_1) \text{ and } (x_2,y_2)\):

\(\frac{y_2-y_1}{x_2-x_1}\)

Notice the numerator is just a subtraction of the y's while the denominator is a subtraction of the x's. The order you choose your y's on top will matter to how you subtract the x's.

You could just line up the points and remember that the y difference goes on top and the x difference goes on bottom.

Mean mode formula  - Mean = {Sum of Observation} ÷ {Total numbers of Observations}

What does the mode mean?

By summing all the numbers in a data collection and dividing by the total number of values in the set, the mean (average) of the data set can be determined.

              A data collection is ordered from least to largest, and the median is the midpoint number. A data set's mode is the number that appears the most frequently.

What are the mean, median, and example?

The most frequent number, or the one that happens the most frequently, is known as the mode. Example: Since the number 2 appears three times, more than any other number, it is the mode of the numbers 4, 2, 4, 3, and 2.

A spurious correlation is a correlation between two variables that appears to be causally linked but is actually due to the influence of a third variable that is not considered. The correct answer is  spurious correlation.

Spurious correlations are correlations that exist between two variables, but they are not actually causally related to one another, despite the fact that they appear to be causally related at first glance. The relationship between two variables may be accounted for by a third variable that was previously overlooked or not considered, causing the original correlation to be explained away. Spurious correlations are commonly found in science and research, and they can lead to misleading results if not properly identified and accounted for. It is critical to account for all potential confounding variables in order to establish causal links between variables and avoid spurious correlations. Therefore, researchers must carefully consider all variables that might influence the relationship between two variables to avoid drawing inaccurate conclusions.

A 3x3 matrix, the rank can be 0, 1, 2, or 3, depending on the values of the entries in the matrix.

The rank of a matrix is the number of linearly independent rows or columns in the matrix.  The rank of a 3x3 matrix can be found by performing row reduction to obtain an echelon form, and then counting the number of non-zero rows.

For example, let's consider the following 3x3 matrix:

a11 a12 a13

a21 a22 a23

a31 a32 a33

Performing row reduction, we can obtain an echelon form:

a11 a12 a13

0   a22' a23'

0   0    a33'

Here, a22' and a33' represent the pivots of the matrix, and the number of non-zero rows in the echelon form is equal to the rank of the matrix.

Therefore, for a 3x3 matrix, the rank can be 0, 1, 2, or 3, depending on the values of the entries in the matrix.

Step-by-step explanation:

In the trigonometric function, the value of \(sin\theta = \frac{1}{2}\) and \(cos\theta=\frac{\sqrt3}{2}\).

The functiοns οf an angle in a triangle are knοwn as trigοnοmetric functiοns, cοmmοnly referred tο as circular functiοns. In οther wοrds, these trig functiοns prοvide the relatiοnship between a triangle's angles and sides. There are five fundamental trigοnοmetric functiοns: sine, cοsine, tangent, cοtangent, secant, and cοsecant.

Here the given  \(\theta = \frac{-\pi}{6}\)

Now put   \(\theta = \frac{-\pi}{6}\) into sin\(\theta\) then,

=> sin \((\frac{-\pi}{6})\)

=>  \(\frac{1}{2}\)

Now put    \(\theta = \frac{-\pi}{6}\) into cos\(\theta\) then,

=> cos \((\frac{-\pi}{6})\)

=> \(\frac{\sqrt3}{2}\)

Hence the value of \(sin\theta = \frac{1}{2}\) and \(cos\theta=\frac{\sqrt3}{2}\).

 f(t) = L^(-1){1 / (s^2 + s)} Inverse Laplace transform tables or techniques, determine the time-domain function f(t) that satisfies the given integral equation.

The Laplace transform is a powerful mathematical tool that can be used to solve complex integral equations, like the one you've provided: f(t) + t * ∫(t - τ)f(τ)dτ = t.

To solve this equation using the Laplace transform, follow these steps:

1. Apply the Laplace transform to both sides of the equation. The Laplace transform of f(t) is F(s), and the Laplace transform of t is 1/s^2. The integral equation becomes:

  L{f(t)} + L{t * ∫(t - τ)f(τ)dτ} = L{t}

  F(s) + L{t * ∫(t - τ)f(τ)dτ} = 1/s^2

2. Next, apply the convolution theorem to the integral term. The convolution theorem states that L{f(t) * g(t)} = F(s) * G(s). In this case, f(t) = t and g(t) = (t - τ)f(τ):

  F(s) + L{t} * L{(t - τ)f(τ)} = 1/s^2

3. Now, substitute the known Laplace transforms for t and f(t):

  F(s) + (1/s^2) * F(s) = 1/s^2

4. Combine the terms containing F(s):

  F(s) * (1 + 1/s^2) = 1/s^2

5. Isolate F(s) by dividing both sides of the equation by (1 + 1/s^2):

  F(s) = (1/s^2) / (1 + 1/s^2)

6. Simplify the expression for F(s):

  F(s) = 1 / (s^2 + s)

7. Finally, apply the inverse Laplace transform to F(s) to obtain the solution for f(t):

  f(t) = L^(-1){1 / (s^2 + s)}

Using inverse Laplace transform tables or techniques, you can determine the time-domain function f(t) that satisfies the given integral equation.

Answer:

Step-by-step explanation:

I got it right

Point (3, - 4) is located on the line represented by the equation

y + 4 =- 5(x - 3).

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

Given, Equation is y + 4 = -5(x - 3).

We'll confirm the points by the given options putting the value of x and checking the corresponding y value.

y + 4 = -5(x - 3).

y + 4 = - 5x + 15.

y = - 5x + 11.
