The statement that is true about the graphs include the following: D. both graphs have the same horizontal asymptotes.

In Mathematics, a horizontal asymptote can be defined as a horizontal line (y = b) where the graph of a function approaches the line as the input values (domain or independent value) approach negative infinity (-∞) to positive infinity (∞).

In this context, the line passing through the ordered pair (0, 3) on the graph of this exponential decay function represents a horizontal asymptote and it has an equation of y = -4, as shown in the image attached above.

This hypothesis test can be set up as a one-tailed test, where the null hypothesis is that the mean is equal to $23,000 and the alternative hypothesis is that the mean is greater than $23,000.

The p-value, which is the probability of obtaining a test statistic as extreme or more extreme than the one observed, given that the null hypothesis is true, can then be used to determine whether to reject or fail to reject the null hypothesis.

In this case, if the p-value is very small, it indicates strong evidence against the null hypothesis and in favor of the alternative hypothesis.

This means that it is highly unlikely that the mean subscription cost per customer is equal to $23,000, given the sample data and the assumptions of the test.

Therefore, it is appropriate for the software company to make the conclusion that the mean is greater than $23,000. However, it is important to note that the conclusion should be based on the assumptions of the test being met and the sample being representative of the population of customers.

Additionally, it is always good practice to report the results of the test, including the p-value, the sample mean, the sample standard deviation, and the sample size, to provide context for the conclusion.

If Stephanie recorded the time, in minutes, she took to walk from home to work {15,16,18,20,21} and the time, in minutes, she took to walk from work to home {14,21,21,25,27} the best conclusion Stephanie can make is:

D. Stephanie’s walk times are more spread out going to work than coming home.

The data Stephanie collected shows that the range of times for walking to work is greater than for walking home. The range for walking to work is 15-21 minutes, while the range for walking home is 14-27 minutes. This indicates that Stephanie’s walk times are more spread out going to work than coming home.

This suggests also that Stephanie may be taking a more direct or efficient route when walking home, while she may be taking a more leisurely or meandering route when walking to work. It is possible that this could be due to a variety of factors, such as traffic, terrain, or the presence of stops along the way.

The data also reveals that the average time for walking to work is 18.4 minutes, while the average time for walking home is 20.6 minutes. This indicates that, on average, Stephanie takes slightly longer to walk home than to work.

Option C has an x larger than or equal to 5 domain and a y less than or equal to 3 range. y = negative Start Root x minus 5 End Root + 3.

What is Domain and Range of Functions?

Let's consider a function y=f(x) where x is a set of values such as f exists. All the values of x are called the domain of f. Similarly, f takes a set of values when x takes values in its domain. All the values f could take is its range. We know the domain and range of f are, respectively x≥5,y≤3. Since all the options contain a square root, we already know the domain will be restricted by the argument of a square root, that is, it must be non-negative. From the given domain, we construct the argument of the square root x≥5 x-5≥0. It corresponds to the argument of a square root that must be non-negative. So our function must contain √x-5. Now about the range, the square root is assumed as positive or zero, and the range is restricted as less or equal to zero, so we operate the inequality for y

y≤3=>0≤3-y=>3-y≥0

Now we can safely say

3-y=√x-5

The estimated volume of the given cuboid is 736 inch³

In geometry, a cuboid is a three-dimensional figure or geometrical shape that has 6 faces, 12 edges, and 8 vertices. The space occupied by the cuboid is known as the Volume of the cuboid.  

The dimensions of the cuboid are Length, Width, and Height. The formula for the volume of the cuboid is given by

Volume of cuboid = Length × Width × Height  

Here we have

Measurements cuboid are

Length = 22.8 inches  

On rounding to a whole number, Lenght = 23 inches

Width = 1.8 inches

On rounding to a whole number, Width = 2 inches

Height = 15.8 inches

On rounding to a whole number, height = 16 inches  

As we know

Yes, it is possible to choose a random natural number in such a way that every number is equally likely to be chosen.

Suppose we use a fair die with an infinite number of sides, where each face corresponds to a different natural number, and roll the die to determine the randomly selected number. Here, each natural number has an equal probability of being chosen.

Alternatively, we could use a pseudorandom number generator to generate a sequence of numbers that appear to be randomly distributed and choose one of the numbers in the sequence as the randomly selected natural number. In this case, while the process of generating the numbers is deterministic, the numbers themselves appear to be randomly chosen and each natural number has an equal probability of being chosen.

It is also possible for every number to have a positive (nonzero) probability of being chosen, as long as the probabilities are defined in such a way that they sum up to 1. This can be achieved by using a uniform distribution where each natural number has a positive but nonzero probability of being chosen.

The x-axis is the horizontal center line on the coordinate plane (left to right). The y-axis is the vertical center line on the coordinate plane. The point where the x and y axis interact, identified by 0, is called the origin.

This point is located at coordinates (0,0). The x-axis is usually associated with the horizontal axis in a two-dimensional graph and is typically used to represent different categories of data. The y-axis is associated with the vertical axis and is used to represent a range of values from high to low.

The formula for determining the coordinates of a point is (x,y). The x-coordinate is the distance from the origin on the x-axis and the y-coordinate is the distance from the origin on the y-axis. For example, if a point has an x-coordinate of 4 and a y-coordinate of -3, the coordinates of the point would be (4,-3). To calculate the distance between two points, you can use the distance formula, which is the square root of the sum of the squares of the differences between the x-coordinates and the y-coordinates. For example, if the coordinates of point A are (2,3) and the coordinates+ of point B are (7,1), the distance between A and B would be calculated by taking the square root of (5-2)^2+(1-3)^2, which would equal 5.

The equation of the line that passes through (-2,1) and is perpendicular to y = -5x² is y = -10x + 21

The equation of a line is a mathematical representation of the relationship between its x and y values.

In this case, we are given a line that passes through the point (-2,1) and is perpendicular to y = -5x².

To find the equation of this line, we first need to find the slope of the line that is perpendicular to y = -5x².

The slope of a line can be found by finding the derivative of the original equation.

In this case, the derivative of

=> y = -5x² is -10x,

which gives us the slope of -10x.

Since we know that the line passing through (-2,1) is perpendicular to

y = -5x²,

we can use the point-slope form of the equation of a line.

The point-slope form of the equation is given by

=> y - y1 = m(x - x1),

where m is the slope and (x1, y1) is a point on the line.

Plugging in the values, we have

=> y - 1 = -10(x + 2).

We can simplify this equation further by distributing the -10 and combining like terms.
