3y = 60°, 2y = 40° ,     4x = 104°, x = 26°, y = 50°

Step-by-step explanation:

Triangle g

180° = 80° + 3y + 2y

100° = 5y

y = 20°

Triangle h

y = 180° - 130°

y = 50°

180° = 4x + x + 50°

130° = 5x

x = 130 / 5

x = 26°

The statement cross-tabulation with two variables is known as twice-tabulation is false because there is no such term as "twice-tabulation" in the context of statistical analysis.

Cross-tabulation, also known as contingency table analysis, involves the analysis of categorical variables by creating a table that shows the frequency or distribution of one variable based on the levels of another variable.

It allows for the examination of the relationship between two variables, highlighting any associations or patterns that may exist. Each cell in the cross-tabulation table represents the count or proportion of observations that fall into specific combinations of categories from the two variables.

The term "twice-tabulation" does not exist in statistical literature and is not commonly used to refer to cross-tabulation with two variables. The correct term to describe this statistical technique is simply cross-tabulation or contingency table analysis.

the inequality that represents the possible sale prices, in dollars, when the total profit will be less than $2,600 is: 11z² - 162z + 550 > 0.

How to solve?

To represent the possible sale prices, in dollars, when the total profit will be less than $2,600, we need to set the expression -22z² + 324z + 1,500 to be less than 2,600 and solve for z:

-22z² + 324z + 1,500 < 2,600

Simplifying:

-22z² + 324z - 1,100 < 0

Dividing by -2 gives:

11z² - 162z + 550 > 0

Therefore, the inequality that represents the possible sale prices, in dollars, when the total profit will be less than $2,600 is:

11z² - 162z + 550 > 0.

Answer:C 151

Step-by-step explanation:

7 * 15=105 + 46=151

Answer: 788

Step-by-step explanation:

In fluid mechanics, the steady two-dimensional flow of a fluid can be described using a mathematical concept known as the stream function. The stream function is a scalar function denoted by Ψ(x, y), where (x, y) represents the coordinates in the fluid domain. The stream function provides a way to visualize and analyze the flow patterns of the fluid.

The stream function is a fundamental concept in fluid mechanics that helps describe the motion of a fluid in two dimensions. It is particularly useful for analyzing incompressible and irrotational flow, where the fluid velocity can be expressed as the derivatives of a scalar function.

The stream function is defined such that its partial derivatives with respect to the spatial coordinates (x and y) give the velocity components in the x and y directions, respectively. That is, u(x, y) = ∂Ψ/∂y and v(x, y) = -∂Ψ/∂x, where u(x, y) and v(x, y) represent the velocity components in the x and y directions, respectively.

By defining the stream function in this way, the velocity field can be easily obtained from the stream function, and vice versa. This provides a convenient way to analyze the flow patterns without directly solving the complex fluid equations.

The streamlines in a fluid flow correspond to the contours of constant stream function. These lines represent the path traced by fluid particles as they move through the flow field. By visualizing the streamlines, we can gain insights into the flow behavior, such as identifying regions of high or low velocity, areas of stagnation, and the overall flow pattern.

Moreover, the stream function also helps in determining properties of the flow, such as the mass flow rate, circulation, and vorticity. It is a powerful tool for solving various fluid mechanics problems, including the design and analysis of fluid systems, aerodynamics, and hydrodynamics.

In summary, the stream function is a mathematical function used to describe the steady two-dimensional flow of a fluid. It allows us to visualize and analyze the flow patterns, determine the velocity components, and obtain valuable insights into the behavior of the fluid. It is a fundamental tool in fluid mechanics that simplifies the analysis and understanding of fluid flow.

a) The total number of different sequences of process and control samples each day is 823,543. b) The total number of different sequences of process and control samples each day is 120. c) The total number of different sequences of process and control samples each day, considering the first test as a control sample, is 46656.

a) To calculate the number of different sequences of process and control samples each day, we can consider the samples as distinguishable. We have 5 process samples and 2 control samples.

For each position in the sequence, we have 7 choices (5 process samples or 2 control samples). Since the samples are independent and can be selected in any order, we can use the multiplication principle.

Therefore, the total number of different sequences of process and control samples each day is 7⁷ = 823,543.

b) Now, let's consider the five process samples to be different and the two control samples to be identical.

We have 5! (5 factorial) ways to arrange the process samples among themselves. However, the two control samples are identical, so they remain fixed in their positions.

Therefore, the total number of different sequences of process and control samples each day is 5! = 120.

c) If the first test of each day must be a control sample, we need to consider the control sample fixed in the first position. We have 1 choice for the first position (control sample) and 6 choices for the remaining 6 positions (5 process samples and 1 control sample).

Therefore, the total number of different sequences of process and control samples each day, considering the first test as a control sample, is 1 * 6⁶ = 46656.

Answer:

\(-\frac{22}{91} = x\)

Step-by-step explanation:

To solve the equation \(3x - 23 = 94x - 1\), we'll follow these steps:

Start by simplifying the equation by combining like terms. In this case, we have terms with x on both sides, as well as constants:

\(3x - 23 = 94x - 1\)

To isolate the x terms, we can subtract 3x from both sides of the equation:

\(3x - 3x - 23 = 94x - 3x - 1\)

Simplifying further, we get:

\(-23 = 91x - 1\)

Next, we want to isolate the constant term on one side of the equation. We can do this by adding 1 to both sides:

\(-23 + 1 = 91x - 1 + 1\)

Simplifying further:

\(-22 = 91x\)

Finally, we can solve for x by dividing both sides of the equation by 91:

\(-\frac{22}{91}=\frac{91x}{91}\)

Simplifying further:

\(-\frac{22}{91} = x\)

Therefore, the solution to the equation \(3x - 23 = 94x - 1\) is \(-\frac{22}{91} = x\)

130 estimated to the nearest integer is 130 itself as 130 itself is an integer.

Integers are numbers which includes the set of natural numbers, 0 and the negatives of all those natural numbers.

Set of integers are usually denoted as Z.

A number is normally rounded to the nearest integer when it is decimal.

First we have to look at the tenths place.

When the digit in the tenths place is 5 or numbers greater than 5, then increase digit in the ones place by 1.

If the digit in tenths place is less than 5, then leave the ones place as such.

Suppose that the number is 1.30.

Then the digit in tenths place is 3, less than 5. So leave the digit in one place which is 1, as such.

So 1.30 rounded to the nearest integer is 1.

Here 130 itself is an integer.

Hence 130 rounded to nearest integer is 130.

Answer:

  3.56 kg

Step-by-step explanation:

You want the mass of a model that is 45 cm tall and has a density of 1200 kg/m³ when the statue it is modeling is 270 cm tall, has a density of 2500 kg/m³, and a mass of 1600 kg.

The ratio of volumes of the model to the statue is the cube of the ratio of their heights:

  Vm/Vs = (Hm/Hs)³

  Vm = Vs(Hm/Hs)³ = (1600 kg)/(2500 kg/m³)·((45 cm)/(270 cm))³

  Vm ≈ 0.002963 m³

The mass of the model is the product of its volume and its density:

  Mm = Vm·ρ = (0.002963 m³)(1200 kg/m³) ≈ 3.56 kg

The mass of Justin's model is about 3.56 kg.

__

Additional comment

The relationship between density, volume, and mass is ...

  ρ = mass/volume

This can be rearranged to ...

  volume = mass/ρ

Which is the expression we used for Vs in the first section above.

(We used V and H for volume and height with 'm' and 's' signifying the model and the statue, respectively.)

<95141404393>

The mass of Justin's model is approximately 3.57 kg., rounded to 3 significant figures.

To find the mass of Justin's model, we can use the concept of mathematical similarity.

Mathematical similarity means that corresponding dimensions of two objects are proportional. In this case, Since the densities are also given, we can use the volume ratio to find the mass ratio.

Let's calculate the volume ratio first:

Volume ratio = (Height of model / Height of statue)^3

            = (45 cm / 270 cm)^3

            = (0.1667)^3

            = 0.00463

Now, using the density ratio:

Density ratio = Density of model / Density of statue

            = 1200 kg/m³ / 2500 kg/m³

            = 0.48

Finally, we can find the mass of Justin's model by multiplying the mass of the statue by the volume ratio and density ratio:

Mass of Justin's model = Mass of statue * Volume ratio * Density ratio

                     = 1600 kg * 0.00463 * 0.48

                     = 3.5712 kg

Rounding to 3 significant figures, the mass of Justin's model is approximately 3.57 kg.

Graph C best represents the distance of the two runners from the lake, D, in meters, over time, t, in minutes.

What is the rate of change?

The rate of change is also called the slope. On a graph, the rate of change is the ratio of the change in the y-values to the change in the x-values between two data points.

As Carlos has a steady pace and his changes in distance from the lake are constant, his distance graph would be a straight line with a constant slope. On the other hand, Stephanie has a slower rate of change when she turns at the lake. Therefore, her distance graph would be a curve.

Since the graph should show the distance of the two runners from the lake over time, the X-axis should represent time (in minutes), and the Y-axis should represent the distance (in meters).

Based on the given information, the graph that best represents the distance of the two runners from the lake over time is:

Graph C:

In Graph C, the line represents Carlos's distance from the lake, and the curve represents Stephanie's distance from the lake.

The line is straight, indicating that Carlos's rate of change is constant, and the curve shows that Stephanie's rate of change is slower as she turns at the lake.

Hence, the graph C best represents the distance of the two runners from the lake, D, in meters, over time, t, in minutes.

Given that ⁵∫₀ (x)x = -9 and ⁵∫₀ (x)x = 26, we need to evaluate the integral ⁵∫₀ ((x)+(x))x. By applying the linearity property of integrals, we can split the integral into two parts: ⁵∫₀ (x)x dx + ⁵∫₀ (x)x dx. Substituting the given values, we have -9 + 26 = 17 as the result of the integral.

To calculate ⁵∫₀ ((x)+(x))x, we can apply the linearity property of integrals, which states that the integral of a sum is equal to the sum of the integrals.

Therefore, we can rewrite the integral as ⁵∫₀ (x)x dx + ⁵∫₀ (x)x dx.

Substituting the given values, we have ⁵∫₀ (x)x dx + ⁵∫₀ (x)x dx = -9 + 26 = 17.
