Which equation shows the variable terms isolated on one side and the constant terms isolated on the other side for the equation Negative one-half x + 3 = 4 minus one-fourth x?
Negative one-fourth x = 1
Negative three-fourths x = 1
7 = one-fourth x
7 = three-fourths x

We need to integrate the function

y = 2x - x² with respect to x, from x = 0 to x = 2.

The graph of the function intersects the x-axis at x = 0 and x = 2.

So,

Area of region R = ∫[0,2] (2x - x²) dx

= [x² - (1/3)x³] from 0 to 2

= [2² - (1/3)(2)³] - [0² - (1/3)(0)³]

= 4/3

Now, let's find the equation of the line y = cx. Since the line passes through the origin (0,0), we have y = cx.

To find the value of c that divides the region R into two equal subregions, we need to find the value of x where the

area under the curve y = 2x - x² is equal to the area under the line y = cx.

∫[0,a] (2x - x²) dx = ∫[0,a] cx dx

[2x²/2 - x³/3] from 0 to a = [c/2 x²] from 0 to a

2a²/2 - a³/3 = c/2 a²

We multiply both sides by 6, we get:

12a² - 2a³ = 3ac

2a² - (1/3)a³ = (1/2)ac

2a - (1/3)a² = (1/2)c

c = (4a - (2/3)a²)/2

We know that the area under the line is equal to the area under the curve up to the point of intersection, we have:

∫[0,a] (2x - x²) dx = ∫[0,a] (cx) dx - ∫[a,2] (2x - x²) dx

2a²/2 - a³/3 = c/2 a² - 2a² + (8/3)a³ - 4a + (4/3)a²

10a³/3 - 7a² + 4a = 0

a = 0, 1.4105, -0.6172

The only value of a that is within the range 0 to 2 is a = 1.4105. Substituting this value into the equation for c, we get:

c = (4a - (2/3)a²)/2 = 1.636

Histogram would be the most appropriate graphical representation for the collected data,  because it shows each individual data point.

A histogram is a graphical representation of a distribution of continuous data that is used to visualize the underlying frequency distribution of a set of data. Here are the general steps to plot a histogram:

1. Choose the appropriate number of bins: The first step in creating a histogram is to choose the number of bins or intervals that the data will be divided into. This decision is based on the number of data points and the range of the data.

2. Determine the range of the data: Determine the range of the data, which is the difference between the largest and smallest values in the data set.

3. Calculate the width of each bin: Divide the range of the data by the number of bins to determine the width of each bin.

4. Plot the horizontal axis: The horizontal axis of the histogram represents the range of the data and is divided into the chosen number of bins.

5. Plot the vertical axis: The vertical axis of the histogram represents the frequency or density of the data.

6. Count the number of observations: Count the number of observations that fall into each bin.

7. Plot the bars: Plot the bars of the histogram such that the height of each bar corresponds to the number of observations in each bin.

8. Label the axes and title: Finally, label the horizontal and vertical axes appropriately and give the histogram an appropriate title.

Histogram would be the most appropriate graphical representation for the collected data of milligrams of Vitamin C from 100 different gummy vitamins sold in the world.

A histogram is a graph that displays the distribution of a continuous data set using bars. It is useful for showing the frequency distribution of a large data set and helps to identify patterns or outliers in the data.

In this case, the milligrams of Vitamin C is a continuous variable, and the histogram would display the frequency of different milligram ranges. It would show the concentration range of the vitamin C in the gummy vitamins sold worldwide and provide an overall picture of the distribution of the data.

The calculated perimeter of the fountain when x = 2 feet is 36 feet.

The area of the rectangular fountain is given by:

16x² + 8x + 1 = (4x + 1)(4x + 1)

Since the dimensions of the rectangle have the form ax + b, we can write:

Length = 4x + 1

Width = 4x + 1

The perimeter of a rectangle is given by the formula:

P = 2(L + W)

Substituting the values of L and W, we get:

P = 2(4x + 1 + 4x + 1) = 2(8x + 2) = 16x + 4

When x = 2 feet, the perimeter of the fountain is:

The statement "random sampling helps to reduce bias" is true. Random sampling is a statistical technique where each member of the population has an equal chance of being included in the sample.

By randomly selecting participants, the sample is more likely to be representative of the population, which helps to reduce bias.

Random sampling helps to reduce bias because it eliminates systematic bias, which can occur when certain individuals or groups are overrepresented or underrepresented in the sample.

For example, if a researcher only sampled individuals from a certain demographic group, the results of the study may not be generalizable to the larger population.

Random sampling also helps to increase the precision of the estimate of the population parameter, as it reduces the variability in the sample. This allows researchers to draw more accurate conclusions about the population based on the sample data.

The slope between the two points (-2,3) (4,1) is the line perpendicular to the line through (-2,3) and (4,1) is y = 3x + 9.

To discover the slant between the two focuses (-2,3) and (4,1), able to utilize the incline equation: incline = (y2 - y1) / (x2 - x1)

slant = (1 - 3) / (4 - (-2))

= -2 / 6

= -1/3, So the slant between the two focuses is -1/3.

To discover the line that features an opposite slant, we have to keep in mind that the slants of opposite lines are negative reciprocals of each other. That's, in case the incline of one line is m, at that point the slant of a line opposite to it is -1/m.

So, the incline of the line opposite to the line through (-2,3) and (4,1) is:

-1/(-1/3) = 3

y - 3 = 3(x - (-2))

y - 3 = 3x + 6

y = 3x + 9

Triangle is a three-sided geometric shape. It has three vertices which join together to form three sides. The sum of the three angles in a triangle is always equal to 180°. It can be classified into three types, namely equilateral, isosceles, and scalene based on the length of the sides. Triangles can also be classified as right, obtuse, or acute depending on the angles. Triangles are one of the most basic shapes in geometry and are used in many real-world applications such as architecture and engineering.

To answer this question, we need to use the Pythagorean theorem, which states that the sum of the squares of the two sides of a right triangle is equal to the square of the hypotenuse.

The surface area of the rectangular pyramid is approximately 567.9 in².

What is rectangular pyramid?

A rectangular pyramid is a type of pyramid that has a rectangular base and four triangular faces that meet at a common vertex. The rectangular base of a rectangular pyramid can be any rectangle, meaning that the length and width can be different. The four triangular faces of a rectangular pyramid are congruent, which means they are the same size and shape. The height of the rectangular pyramid is the distance between the vertex and the center of the base. The surface area of a rectangular pyramid can be calculated by finding the area of each face and adding them together.

To find the surface area of the rectangular pyramid, we need to find the area of each face and add them together.

First, let's find the area of the rectangular base:

Area of base = length x width = 13 in x 17 in = 221 in²

Next, let's find the area of the larger triangular faces:

Area of each larger triangular face = (1/2) x base x height = (1/2) x 17 in x 11 in = 93.5 in²

Total area of both larger triangular faces = 2 x 93.5 in² = 187 in²

Finally, let's find the area of the smaller triangular face:

Area of smaller triangular face = (1/2) x base x height = (1/2) x 13 in x 12.3 in = 79.95 in²

Now, we can find the total surface area of the rectangular pyramid by adding the areas of all the faces:

Total surface area = area of base + area of both larger triangular faces + area of smaller triangular face

Total surface area = 221 in² + 187 in² + 79.95 in²

Total surface area = 488.95 in²

Therefore, the surface area of the rectangular pyramid is approximately 567.9 in².

Answer:

8 is closer to 10, so 219.8 rounded is 220.

The critical value from the chi-square distribution table is 15.51 for 11 degrees of freedom and a 0.01 significance level. Since the chi-square statistic (23.9) is greater than the critical value (15.51), we can reject the null hypothesis

Chi-square goodness-of-fit test is used to compare observed data with theoretical data, in order to determine how closely the two sets of results match. It is used to assess whether a sample data fits a given distribution.

To test the claim that the rate of violent crime is the same for each month, we can use a chi-square goodness-of-fit test.

The null hypothesis is that the rate of violent crime is the same for each month, while the alternative hypothesis is that the rate of violent crime is not the same for each month.

The chi-square statistic is calculated as follows:

X₂ = Σ(Oi - Ei)2 / Ei

where Oi is the observed number of crimes for each month and Ei is the expected number of crimes for each month.

The expected number of crimes for each month can be calculated by dividing the total number of crimes (8,814) by 12, which gives us an expected value of 734.5.

Using these values, we can calculate the chi-square statistic:

X₂ = (786 - 734.5)2 / 734.5 + (704 - 734.5)2 / 734.5 + (835 - 734.5)2 / 734.5 + (826 - 734.5)2 / 734.5 + (900 - 734.5)2 / 734.5 + (868 - 734.5)2 / 734.5 + (920 - 734.5)2 / 734.5 + (901 - 734.5)2 / 734.5 + (856 - 734.5)2 / 734.5 + (862 - 734.5)2 / 734.5 + (783 - 734.5)2 / 734.5 + (797 - 734.5)2 / 734.5

X₂ = 23.9

We can compare this value to the critical value from the chi-square distribution table, which is 15.51 for 11 degrees of freedom and a 0.01 significance level.

Since the chi-square statistic (23.9) is greater than the critical value (15.51), we can reject the null hypothesis and conclude that the rate of violent crime is not the same for each month.

This indicates that there is a statistically significant difference in the rate of violent crime for each month.
