Graph the line with slope 2 passing through the point (-3, 3).

Answers

Answer 1

Answer:

the equation of the line is y = 2x + 9

graph below

Step-by-step explanation:

The slope intercept form is y = mx + b

y = y coordinate (given: 3)

m = slope (given: 2)

x = x coordinate (given: -3)

b = y intercept need to find

The y - intercept is when x = 0

y = mx + b

3 = 2(-3) + b

3 = -6 + b

3 + 6 = -6 + 6 + b

9 = b

y = 2x + 9

A particle moves in a straight line and has acceleration given by a(t)=4t−1. Its initial velocity is v(0)=−3 cm/s and it's initial displacement is s(0)=4 cm. Find its position function s(t).

Answers

The position function s(t) for a particle with acceleration a(t) = 4t - 1, initial velocity v(0) = -3 cm/s, and initial displacement s(0) = 4 cm is s(t) = t^2 - t + 4t + 4 cm.

To find the position function s(t), we need to integrate the acceleration function a(t) with respect to time twice. Given that a(t) = 4t - 1, we first integrate it once to obtain the velocity function v(t). The integral of 4t - 1 with respect to t is 2t^2 - t + C1, where C1 is a constant of integration. Since the initial velocity is v(0) = -3 cm/s, we can substitute t = 0 and v(0) = -3 into the velocity function to find C1. Solving for C1, we get C1 = -3.

Next, we integrate the velocity function v(t) = 2t^2 - t - 3 with respect to t to find the position function s(t). The integral of 2t^2 - t - 3 with respect to t is (2/3)t^3 - (1/2)t^2 - 3t + C2, where C2 is another constant of integration. Using the initial displacement s(0) = 4 cm, we substitute t = 0 and s(0) = 4 into the position function to find C2. Solving for C2, we get C2 = 4.

Therefore, the position function s(t) for the particle is given by s(t) = (2/3)t^3 - (1/2)t^2 - 3t + 4 cm. This function represents the particle's position at any given time t based on its initial velocity, acceleration, and displacement.

In this problem, we use your critical values table to explore the significance of r based on different sample sizes

Answers

To explore the significance of r based on different sample sizes using a critical values table, we need to first calculate the value of r for our sample. Once we have this value, we can use the critical values table to determine if our r value is statistically significant at a given level of significance (usually 0.05).

The critical values table provides us with the critical values for r at different levels of significance and sample sizes. For example, if we have a sample size of 30 and a significance level of 0.05, we would look up the critical value of r in the table for n=30 and α=0.05.

If our calculated value of r falls within the critical values for our sample size and level of significance, then we can conclude that there is a significant correlation between the two variables. However, if our calculated value of r falls outside of the critical values, then we cannot conclude that there is a significant correlation.

Remember to also check the direction and strength of the correlation, as r values can range from -1 to 1, with -1 indicating a perfect negative correlation and 1 indicating a perfect positive correlation.

I hope this helps! Let me know if you have any further questions. And don't worry about giving Brainliest, I'm just here to help.
Hi! I'd be happy to help you with your question. When using a critical values table to explore the significance of the correlation coefficient (r) based on different sample sizes, it is important to consider the following:

1. Sample size (n): This refers to the number of observations in your data set. Larger sample sizes typically yield more reliable results.

2. Significance level (α): This represents the probability of making a Type I error, which is rejecting the null hypothesis when it is true. Common significance levels are 0.05 and 0.01.

3. Critical values: These are values from the table that correspond to a specific sample size and significance level. If the absolute value of your correlation coefficient (r) is greater than the critical value, you can conclude that there is a significant relationship between the two variables.

To use the critical values table, follow these steps:

1. Determine your sample size (n) and significance level (α).
2. Locate the row in the table that corresponds to your sample size (n - 2 degrees of freedom) and the column that corresponds to your chosen significance level (α).
3. Compare the absolute value of your correlation coefficient (r) to the critical value from the table. If the absolute value of r is greater than the critical value, you can conclude that there is a significant relationship between the two variables at the chosen significance level.

The traffic intensity is greater than 50% C. The system resources are inefficiently utilized D. None of the above

Answers

TCP provides error checking to ensure reliable data delivery, making option A the correct answer. Only the propagation delay is not caused by the store-and-forward strategy employed by switching devices.

TCP (Transmission Control Protocol) provides error checking as part of its services. It ensures reliable data delivery by using acknowledgments and sequence numbers to detect and recover from packet loss, errors, or out-of-order delivery. When a TCP receiver receives data, it sends an acknowledgment (ACK) back to the sender to confirm the successful reception of packets. If the sender does not receive an ACK for a particular packet within a specified timeout period, it assumes the packet was lost or damaged and retransmits it.

TCP provides error checking to ensure reliable data delivery, making option A the correct answer.

The propagation delay is the time it takes for a signal to travel from the source to the destination. It is determined by the physical distance between the devices and the speed of signal propagation in the transmission medium. The propagation delay is an inherent characteristic of the medium and cannot be eliminated by switching devices or other strategies.

The other three options—processing delay, queuing delay, and transmission delay—are all caused by the store-and-forward strategy used by switching devices. Processing delay refers to the time taken to examine and process the packet headers. Queuing delay occurs when packets have to wait in a queue before being transmitted. Transmission delay is the time it takes to push the bits onto the transmission medium.

Among the given options, only the propagation delay is not caused by the store-and-forward strategy employed by switching devices.

3. The correct answer is A. The system is very well-engineered.

In a statistical multiplexing system, the queuing delay is the delay experienced by packets waiting in a queue before being transmitted. If the average queuing delay is very close to zero, it indicates that the system is well-engineered and efficiently managing its resources. A well-designed system can minimize or eliminate queuing delays by appropriately allocating resources and ensuring efficient scheduling algorithms.

Traffic intensity, which represents the ratio of the average traffic load to the transmission capacity, does not directly determine the queuing delay. It is possible to have low queuing delays even with high traffic intensity if the system is well-designed.

When the average queuing delay is close to zero, it suggests that the system is well-engineered and efficiently utilizing its resources, as stated in option A.

which of the following is a condition in order for a setting to be considered binomial: group of answer choices the probability of success is the same for each trial. each observation/trial has 3 possible outcomes. the number of outcomes varies on the first success. the trials are dependent on one another.

Answers

The main condition for a setting to be considered binomial is that the probability of success remains the same for each trial, and the other conditions include having 3 possible outcomes for each observation, no variation in outcomes based on the first success, and independence of trials from one another.

A condition for a setting to be considered binomial is that the probability of success is the same for each trial.

In order for a setting to be considered binomial, there are certain conditions that need to be met. The first condition is that the probability of success remains constant for each trial or observation. This means that the likelihood of achieving the desired outcome remains unchanged throughout the entire process.

The second condition states that each observation or trial must have exactly 3 possible outcomes. This implies that there are only three options or choices for each trial, typically categorized as success, failure, or a neutral outcome.

The third condition is that the number of outcomes should not vary based on the occurrence of the first success. This means that the probability of success is not affected or altered by the outcome of previous trials.

Lastly, the fourth condition is that the trials or observations must be independent of one another. This implies that the outcome of one trial should not impact the outcome of subsequent trials.

Therefore, the main condition for a setting to be considered binomial is that the probability of success remains the same for each trial, and the other conditions include having 3 possible outcomes for each observation, no variation in outcomes based on the first success, and independence of trials from one another.

Answers

The odds of choosing a red and a blue are 6/20 (4/20), or 3/5.

What is meant by probability?The area of mathematics known as probability deals with numerical descriptions of how likely it is for an event to happen or for a claim to be true.A number between 0 and 1 is the probability of an event, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty. Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability. The likelihood that something will happen is known as probability. The number of possible outcomes is divided by the total number of possible outcomes to determine probability.

The balls in the bag are unaware of what was drawn the first time because the two choices are separate.

Six of the 20 pebbles in the bag are red. The odds of selecting a red are 6/20.

How many times does 6 go into 60?

Answers

The number-of-times the "number-6" go into the "number-60" is exactly "10-times".

When we divide the "number 60" by "6", we are asking how many times the "number 6" can be evenly divided into "60" without any remainder.

In other words, we are searching for the quotient of the division operation.

To find the quotient, we divide the "number 60" by "6",

On dividing "60" by "6", the result is "10", which means that the "number 6" can go into "60" exactly "10 times", because "6" multiplied by "10" equals "60", with no remainder.

This means that there is a 50% chance that the outcome of a trial will be 17.

The given table represents the frequency distribution of a discrete random variable X, which has four possible outcomes: 15, 16, 17, and 18. The frequency of each outcome indicates the number of times that outcome occurs in 16 trials.

To calculate the probability of a specific outcome, we divide its frequency by the total number of trials. In this case, we want to find P(X=17), which is the probability that the outcome of a trial is 17.

Linda i putting brick around her yard, which i 15 meter by 11 meter. Each brick i 15 meter long. How many brick doe he need?

Answers

The Linda will need to use 4 bricks to surround her yard.

To find the number of bricks Linda needs, we need to find the total length of the perimeter of the yard and then divide that by the length of each brick.

The perimeter of the yard is equal to 2 times the sum of the length and width:

2(15 + 11) = 2 x 26 = 52 meters.

52 meters / 15 meters/brick = 3.46 brick

Therefore, Linda needs 3.46 brick (rounded up to 4 bricks).

Perimeter refers to the total length of the boundary of a two-dimensional shape. It is a measure of how long the edge of a shape is. Perimeter is a crucial concept in geometry and is widely used in mathematical and real-life applications. The formula for perimeter varies based on the shape of the object. For a rectangle, the perimeter is found by adding the lengths of all four sides, while for a circle, it is calculated using the formula 2πr, where r is the radius. The perimeter of a triangle can be calculated by adding the lengths of all three sides.

Perimeter is used in various fields, including architecture, construction, engineering, and landscaping. In architecture, perimeter is used to calculate the amount of material required to build the walls of a building. In construction, perimeter is used to determine the length of fencing required to enclose a site. In engineering, perimeter is used to calculate the length of the road required to construct a highway. In landscaping, perimeter is used to determine the amount of material required to build a retaining wall.
