Answer:

The area of each square is 16 square units.

Step-by-step explanation:

Given,

The two squares are identical.

Hence, their areas are of the same values.

Area of square 1:

\( = 3x + 7 \)

Area of square 2:

\( = 5x + 1 \)

As, their areas are equal,

\(3x + 7 = 5x + 1\)

\(7 - 1 = 5x - 3x\)

\(6 = 2x\)

\( \frac{6}{2} = x\)

\(3 = x\)

Therefore,

\(5x + 1 = 5(3) + 1 = 15 + 1 = 16\)

\(3x + 7 = 3(3) + 7 = 9 + 7 = 16\)

The  359.68 football fields fit in the area of land occupied by SHSU campus.

To determine  Conversion Factor how many football fields fit in the area of land occupied by SHSU campus (1.49 km^2), we need to convert the area to acres and then divide by the area of one football field.

First, let's convert 1.49 km^2 to acres. We know that 1 mile is equal to 1.61 km, and 1 mi^2 is equal to 640 acres.

1.49 km^2 * (1 mi / 1.61 km)^2 * (640 acres / 1 mi^2) = 0.562 mi^2 * 640 acres/mi^2 = 359.68 acres

Now we have the area of the SHSU campus in acres, which is 359.68 acres.

Since 1 acre is equal to 1 football field, we can conclude that 359.68 football fields fit in the area of land occupied by SHSU campus.

The manufacturer would lose a total profit of $100,000 and a per-unit profit of $10 by producing 70,000 units instead of the demanded 80,000 units.

To calculate the total profit and per-unit profit lost, we need to consider the difference between the actual production and the demand, as well as the profit per unit.

Let's assume the profit per unit is $10.

The manufacturer produces 70,000 units, but the demand is for 80,000 units, resulting in a shortage of 10,000 units.

Total profit lost = shortage * profit per unit = 10,000 * $10 = $100,000

Therefore, the total profit lost in this scenario is $100,000.

To calculate the per-unit profit lost, we divide the total profit lost by the shortage:
Per-unit profit lost = total profit lost / shortage = $100,000 / 10,000 = $10

Therefore, the per-unit profit lost in this scenario is $10.

By understanding the difference between the actual production and the demand, as well as the profit per unit, we can determine the total profit and per-unit profit lost when producing fewer units than the demand.

The required image of the dog would be 26.6 cm tall on the screen.

To find the height of the image of the dog on the screen, we need to calculate 140% of its original height when printed on a sheet of paper.

Let's start by converting 140% to decimal form:

140% = 140/100 = 1.4

Next, we multiply the original height of the image (19 cm) by 1.4 to find the height on the screen:

19 cm * 1.4 = 26.6 cm

Therefore, the image of the dog would be 26.6 cm tall on the screen.

For hotels in New York City, a travel web site wants to provide information comparing hotel costs (high, average, low) versus the quality ranking of the hotel (excellent, good, fair, poor). A useful way to summarize these data is to construct a scatter plot.

A scatter plot is a graph that shows the correlation between two variables. A horizontal x-axis and a vertical y-axis are used to plot data points in a scatter plot. Each data point represents a single observation on both the x-axis and the y-axis, and each point on the scatter plot represents a single observation.

The data set, including hotel costs and quality rankings, would be plotted on a scatter plot. The data is plotted using the independent variable on the x-axis and the dependent variable on the y-axis. The data points are spread over the plot in a scattered pattern.

For example, the independent variable is hotel costs, and the dependent variable is quality rankings in this example. A scatter plot is a helpful tool for identifying trends and predicting outcomes. To make sense of the data, a scatter plot can be used to generate a trend line that connects the data points. The trend line is also referred to as a regression line and is used to predict future values of the dependent variable based on the independent variable.

The coordinates of your position If we start at the origin, we are moving only along the x-axis  of  a distance of 7 units in positive direction and then only in the negative y-axis direction and  z-coordinate is zero are (7,-6,0).

The origin is the point in space that has a position of (0, 0, 0), which represents the point where the x, y, and z axes intersect.

The first step is to move 7 units in the positive x direction. The positive x direction is the direction in which x values increase. Therefore, we move to the right along the x-axis to the point (7, 0). This means that we have moved 7 units along the x-axis, and our position is now (7, 0, 0).

The second step is to move downward a distance of 6 units. Since we are not moving in the x direction, we are only changing our position along the y-axis. Moving downward in the y direction means decreasing our y-coordinate. Therefore, we move 6 units downward from our current position to the point (7, -6, 0).

Therefore, the coordinates of our position are (7, -6, 0)

As the sample size rises, the sample distribution approaches a normal distribution.

The sample distribution approaches a normal distribution as the sample size grows. The sampling distribution's mean equals the population's mean if the number of consecutive samples is "infinite".

The Gaussian distribution is the official name for the normal distribution. However, the word "normal" was coined in the nineteenth century after a scientific inquiry revealed that numerous natural events appeared to "deviate from normal" from their typical values.

In his 1889 work Natural Inheritance, naturalist Sir Francis Galton popularized the notion of normal variability as the standard curve.
