On a distance-time graph, a constant slope indicates a constant speed or velocity. The slope of a line on a distance-time graph represents the rate of change of distance with respect to time.

If the slope remains constant, it means that the distance covered per unit of time is consistent throughout the entire duration represented by the graph.

When the slope is constant, it implies that the object or subject being represented is moving at a steady pace. This means that for each unit of time, an equal amount of distance is covered. For example, if the slope of the graph is 2, it indicates that for every unit of time (e.g., 1 second), the object or subject is covering 2 units of distance (e.g., 2 meters).

A constant slope can also suggest uniform motion, where the speed remains constant without any acceleration or deceleration. In this case, the object is moving at a steady rate, maintaining the same speed throughout the given time interval.

It's important to note that the slope's magnitude doesn't provide information about the actual speed; it only indicates that the speed remains constant. The actual speed can be determined by examining the scale and units on the graph.

In summary, a constant slope on a distance-time graph indicates that the object or subject is moving at a constant speed or velocity, covering the same amount of distance per unit of time, suggesting either uniform motion or a steady pace.

Answer:

c

b

Step-by-step explanation:

Step-by-step explanation:

The correct statement in the following is b. The variance of a random walk process increases as a linear function of time. This is because of the fact that it keeps adding the variance of the next increments to the variability we have in getting to where we are now.

Answer:

A

Step-by-step explanation:

The rule for negative exponents is:

\(a^{-n} = \frac{1}{a^n}\)

We have:

\(5^{-2}\)

So, we can create a fraction with 1 as the numerator, and our exponent raised to a positive number as the denominator, and rewrite it as:

\(\frac{1}{5^2}\)

Evaluate the exponent in the denominator

\(\frac{1}{5*5}\\\frac{1}{25}\)

Therefore, choice A, 1/25 is correct.

The corresponding equation is 4q + 3p = 22.

What is the slope of a line ?

The ratio of the change in the y coordinate to the change in the x coordinate is known as a line's b in mathematics.

Y and X, respectively, stand for the net change in the y-coordinate and the net change in the x-coordinate. Locate two locations along the chosen line and find their coordinates.

Find the y-coordinate difference between these two places (rise). Find the difference between the x-coordinates of these two points (run). Subtract the difference in y-coordinates from the difference in x-coordinates (rise/run or slope).

The slope is defined as the relationship between the rise, or vertical change, between two points and the change, or horizontal change, between the same two points and can be represented as an equation.

Given that, coordinates are (p, 1/2) and (-8, q), slope is 3/4.

m = (y2 - y1)/(x2 - x1)

34 = (q - 1/2)/-8 - p

-24 - 3p = 4q - 2

4q + 3p = 22

The corresponding equation is 4q + 3p = 22.

The maximum and minimum voltage for an outlet can vary, but in standard residential outlets in the US, the voltage is typically 115 volts.

For alternating electric current, the number of oscillations per second is determined by its frequency. The frequency is measured in hertz (Hz), which represents the number of complete oscillations per second.

a) In 0.05 seconds, the number of oscillations can be calculated by dividing the time (0.05s) by the period (T), which is the inverse of the frequency. The formula is: Number of oscillations = Time / Period. However, the period can also be expressed as 1/frequency. So, the formula becomes:

Number of oscillations = Time x Frequency.

Given that the time is 0.05 seconds, you need to know the frequency of the alternating current to determine the number of oscillations.

b) The maximum and minimum voltage for an outlet depend on the type of alternating current.

In the case of standard residential outlets in the United States, the voltage is 115 volts.

However, it's important to note that the voltage is not always equal to 115 volts.

In summary, to determine the number of oscillations in 0.05 seconds, you need to know the frequency of the alternating current.

The statement that states the difference between the population parameters between two groups is zero is referred to as the null hypothesis. Therefore, the correct answer is option b: null hypothesis.

In statistical hypothesis testing, we compare the observed data from two groups or samples to determine if there is evidence to support a difference or relationship between the populations they represent. The null hypothesis (option b) is a statement that assumes there is no difference or relationship between the population parameters being compared.

The null hypothesis is typically denoted as H0 and is the default position that we aim to test against. It asserts that any observed differences or relationships are due to chance or random variation.

On the other hand, the alternative hypothesis (option c) states that there is a difference or relationship between the population parameters. The null hypothesis is formulated as the opposite of the alternative hypothesis, assuming no difference or relationship.

Therefore, the correct answer is option b: null hypothesis.

According to the questions there are 5000 students at mountain high school, and 3/4 of these students are seniors. Then, 2125 students do not favor the idea of forming a debate team

To find the number of students who do not favor the idea of forming a debate team, we need to calculate the following:

Number of senior students: 3/4 * 5000 = 3750

Number of senior students in favor: 1/2 * 3750 = 1875

Number of non-senior students: 5000 - 3750 = 1250

Number of non-senior students in favor: 4/5 * 1250 = 1000

Number of students not in favor: Total students - (Senior students in favor + Non-senior students in favor)

Number of students not in favor: 5000 - (1875 + 1000) = 2125

Therefore, 2125 students do not favor the idea of forming a debate team.

Answer:

The function graphed below is \(x = y^{2} - 2\) or \(y = \pm \sqrt{x+2}\).

Step-by-step explanation:

The graph represents a second order polynomial function (a parabola), whose axis of symmetry is the x-axis and whose form is presented as follows:

\(x - h = C\cdot (y-k)^{2}\)

Where:

\(x\), \(y\) - Dependent and independent variable, dimensionless.

\(h\), \(k\) - Horizontal and vertical components of the vertex, dimensionless.

\(C\) - Vertex constant, dimensionless. If \(C > 0\), then vertex is an absolute minimum, otherwise it is an absolute maximum.

After a quick observation, the following conclusions are done:

1) Vertex is an absolute minimum (\(C > 0\)) and located at (-2, 0).

2) Parabola pass through (2, 2).

Then, the value of the vertex constant is obtained after replacing all known values on expression prior algebraic handling: (\(x = 2\), \(y = 2\), \(h = -2\), \(k = 0\))

\(2+2 = C\cdot (2-0)^{2}\)

\(4 = 4\cdot C\)

\(C = 1\)

The function is:

\(x = -2 + 1\cdot y^{2}\)

\(x = y^{2}-2\)

The inverse function of this expression is \(y = \pm \sqrt{x+2}\)

The function graphed below is \(x = y^{2} - 2\) or \(y = \pm \sqrt{x+2}\).

An unnormalized relation refers to a table in a relational database that contains more than one row. This means that there are duplicate rows in the table, which violates the rules of normalization.

Normalization is a process in database design that aims to eliminate data redundancy and ensure data integrity. It involves breaking down a database into multiple tables and defining relationships between them. By doing so, we can efficiently store and retrieve data while minimizing inconsistencies.

In an unnormalized relation, duplicate rows can lead to various problems. For example, it can result in data inconsistencies, as updating one instance of a row may not reflect changes in other duplicate rows. Additionally, it can cause unnecessary storage and maintenance overhead.

To normalize an unnormalized relation, we need to identify the functional dependencies in the table and create separate tables for related data. This helps organize the data and reduces redundancy.

In summary, an unnormalized relation is a table in a relational database that has duplicate rows. It is important to normalize such relations to ensure data integrity and efficiency.

Answer:

C = 7.72 ~ 7.7

Step-by-step explanation:

So when you solve this equetion you must 1st find x then c

we can find x by using cos(60)

cos(60) = x/14

x = cos(60) × 14

x = 1/2 ×14

x = 7

so after we find x we are going to solve c by using cos (25)

cos (25) = X/C = 7/c

cos(25) × C = 7

C = 7/cos (25)

C = 7.72 ~ 7.7

so the solution is 7.7
