 - We do this because in order to add the fractions together, they have to have the same denominator. In this case you find the LCF, (Least Common Factor) of 8 and that turns into the denominator for both.

 - \(\frac{5}{8}\) stays the same, but \(\frac{3}{4}\) changes to \(\frac{6}{8}\) because the LCF if 8, and to get to 8 we had to multiply 4 by 2. So since we multiplied the denominator, you must do the same to the numerator, hence why we went from 3 to 6.

 - Since \(\frac{5}{8}\) and \(\frac{6}{8}\) have the same denominator, all you have to do is add the numerator.

If h > 42 and h < 60, where h is in inches, then we can say 42 < h < 60.

This translates to "the person's height must be between 42 inches and 60 inches, excluding both endpoints".

So for example, if someone is h = 50 inches, then they can go on the ride. This is because 42 < 50 < 60 is true. I've simply replaced h with 50.

On the other hand, something like 42 < 70 < 60 is false, meaning that h = 70 isn't allowed as they are too tall.

The person cannot have a height of h = 42, and they can't have a height of h = 60 either since we're leaving the endpoints out.

As a final example, if the person is h = 40 inches, then they can't ride either because 42 < 40 < 60 is false. They are too short in this case.

Commission is a term commonly used in the sales industry, and it refers to a form of compensation where an individual receives a percentage of the sales they make. In other words, commission is when you make money based on the percentage of the sales you generate.

This type of payment structure is often used to motivate salespeople to work harder and increase their productivity. For example, let's say that you work for a company that sells cars. You are a salesperson, and your job is to sell as many cars as possible. Your commission rate might be set at 3% of the total price of the car. If you sell a car for $30,000, you would earn a commission of $900. Commission is often used in conjunction with a base salary, which is a fixed amount of money that an individual receives regardless of their sales performance. For salespeople, the commission component of their compensation package can be significant, especially if they are highly motivated and successful at generating sales. In summary, commission is when an individual earns money based on a percentage of the sales they generate. It is a common form of compensation used in the sales industry to motivate individuals to work harder and increase their productivity.

The part of the graph that represents the velocity of the ball is the slope of the position-time graph. It corresponds to the steepness or the rate of change of the position of the ball with respect to time.

To determine what is happening to the velocity of the tennis ball with respect to time, we need to analyze the slope of the position-time graph

.If the slope of the graph is increasing, it means the velocity of the ball is increasing over time.

This indicates that the ball is speeding up or accelerating.

If the slope of the graph is decreasing, it means the velocity of the ball is decreasing over time.

This indicates that the ball is slowing down or decelerating.If the slope of the graph is constant, it means the velocity of the ball is constant, indicating a constant speed or no acceleration.

To determine the behavior of the velocity of the tennis ball with respect to time, we need to analyze the shape of the position-time graph or the changes in its slope.

Step-by-step explanation:

Because x =24 and y=17 are both less than 25

answer: 11

because this is a test

Answer:

x = 3/4

Step-by-step explanation:

Step 1: Find possibilities.

Step 2: Solve possibility 1.

Therefore, x = 3/4.

99% confidence that the difference in the proportion of people identifying as "dog person" is between -0.4391 and -0.0653, where the negative sign indicates that a higher proportion of people in the rural area identify as "dog person" compared to those in the city.

To find the 99% confidence interval for the difference in the proportion of people who identify as "dog person" between those living in the city (P1) and those living in the rural area (P2), we can use the formula for the confidence interval for the difference of two proportions.

The formula is given as:

CI = (P1 - P2) ± Z * sqrt((P1 * (1 - P1) / n1) + (P2 * (1 - P2) / n2))

where P1 and P2 are the sample proportions, n1 and n2 are the sample sizes, and Z is the Z-score corresponding to the desired confidence level.

n1 = 201 (sample size for the city)

n2 = 91 (sample size for the rural area)

x1 = 73 (number of people in the city identifying as "dog person")

x2 = 56 (number of people in the rural area identifying as "dog person")

First, we calculate the sample proportions:

P1 = x1 / n1

P2 = x2 / n2

Then, we calculate the standard error:

SE = sqrt((P1 * (1 - P1) / n1) + (P2 * (1 - P2) / n2))

Next, we determine the Z-score for a 99% confidence level. The critical value for a 99% confidence level is Z = 2.576.

Finally, we calculate the confidence interval:

CI = (P1 - P2) ± Z * SE

Now we can substitute the values and calculate the confidence interval.

P1 = 73 / 201 ≈ 0.3632

P2 = 56 / 91 ≈ 0.6154

SE = sqrt((0.3632 * (1 - 0.3632) / 201) + (0.6154 * (1 - 0.6154) / 91)) ≈ 0.0725

Z = 2.576

CI = (0.3632 - 0.6154) ± 2.576 * 0.0725

= -0.2522 ± 0.1869

Rounded to 4 decimal places, the 99% confidence interval for the difference in the proportions is approximately -0.4391 to -0.0653.
