Tom works 12 hours a day at a café. He is paid $8 an hour. How much
money is he paid in 10 days?

Answer:

qualitative and ordinal.

Step-by-step explanation:

They are both two types of qualitative data under Categorical data.

Nominal and ordinal are the levels of measurement for which data can be qualitative. Therefore, the correct option is option A, D.

A categorization that describes the type of information contained inside the importance attributed to variables is called level of measurement and scale of measure. The most well-known classification was created by psychiatrist Stanley Smith Stevens and included four levels or measurement scales: nominal, ordinal, interval, or ratio.

This system of defining several measurement levels originated within psychology and has drawn heavy criticism from academics in other fields. Additional classifications include those made by Chrisman, Mosteller, and Tukey. Nominal and ordinal are the levels of measurement for which data can be qualitative.

Therefore, the correct option is option A, D.

The equation of line in slope intercept form can be written as y = mx + c where m is the slope of line and c is the y intercept.

We are given three equations namely y = 2x -2, y = -x + 1 and y = x - 4 and we need to determine the description of equation, slope and y intercept. The equation y = 2x - 2 is the equation of straight line. If we compare this equation with the slope intercept form of line then, m = 2 and c = -2. Thus, slope is 2 and y intercept is -2. The equation y = -x +1 is the equation of straight line. If we compare this equation with the slope intercept form of line then, m = -1 and c = 1. Thus, slope is -1 and y intercept is 1. This equation y = x - 4is the equation of straight line. If we compare this equation with the slope intercept form of line then, m = 1 and c = -4. Thus, slope is 1 and y intercept is -4.

The technique being described is random sampling without replacement, which is option a.

This technique is called "sampling without replacement."

However, you've also mentioned convenience sampling, which is a different method.

Let me briefly explain both concepts.

Sampling without replacement is a method in which each item, score, event, or participant is chosen from the population and is not returned to the pool for further selections.

This ensures that each element can only be selected once, eliminating the chance of duplication in the sample.

This method is often used in surveys, experiments, and research to maintain the independence of observations and provide a more accurate representation of the population.
Select an item, score, event, or participant from the population.
Record the selected item and remove it from the population.

Repeat steps 1-2 until the desired sample size is obtained.
Convenience sampling, on the other hand, is a non-probability sampling method where researchers select participants based on their accessibility and ease of recruitment.

This approach may introduce bias and limit the generalizability of the study results, as it does not ensure that the sample is representative of the population.
Identify the target population.
Recruit participants who are easily accessible and willing to participate.
Collect data from the selected participants.
In summary, sampling without replacement is a technique that prevents the same item from being selected more than once, while convenience sampling is an approach that focuses on selecting participants based on their accessibility. Both methods serve different purposes in research and should be chosen based on the study's objectives and available resources.

Option a is correct.

To calculate the percent of variance that age at first birth shares with highest grade completed, we can use the coefficient of determination (R-squared). R-squared measures the proportion of the total variance in one variable that can be explained by another variable.

First, we need to perform a regression analysis to obtain the R-squared value. This can be done using statistical software or tools like Excel or SPSS.

Once you have the R-squared value, you can interpret it as the percentage of variance that age at first birth shares with highest grade completed. For example, if the R-squared value is 0.5, it means that 50% of the variance in age at first birth can be explained by the highest grade completed.

In conclusion, the R-squared value obtained from the regression analysis will provide the percentage of variance that age at first birth shares with highest grade completed. The higher the R-squared value, the stronger the relationship between the two variables.

Ivory needs to make an additional 17 successful free throws without a miss to attain a success rate of 75%.

Let's start by finding Ivory's current free-throw success rate:

\(success rate = \frac{number of successful free throws}{total numbers of free throw} =\frac{7}{15}\)

We want to find the number of additional successful free throws Ivory must make to attain a success rate of $75%$, which can be written as:

\(success rate = \frac{numbers of successful free throws}{total numbers of free throws} = \frac{3}{4}\)

Let's call the number of additional successful free throws that Ivory needs to make "x". Then, we can write an equation based on the above expressions for success rate:

\(\frac{7 + x}{15 + x } =\frac{3}{4}\)

To solve for x, we can cross-multiply:

4( 7 + x) = 3 (15 + x)

28 + 4x = 45 + 3x

x= 17

Therefore, Ivory needs to make an additional 17 successful free throws without a miss to attain a success rate of 75%.

The linear equation is y = 6.75x  + 5.5, while the rate of change is 6.75

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

The given parameter is the table of values

On the table of values, we have the following points

(x, y) = (1, 12.25) and (10, 73)

The rate of change is calculated as

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

So, we have

m = (73 - 12.25)/(10- 1)

Evaluate

m = 6.75

The linear equation is calculated as

y = m(x - x1) + y1

So, we have

y = 6.75(x - 1) +12.25

Evaluate

y = 6.75x  + 5.5

The initial speed of the object launched at an angle of 11.7 degrees from the horizontal can be calculated by using the range formula, and it is rounded to 1 decimal place.it is approximately 9.9m/s.

To find the initial speed of the object, we can use the range formula for projectile motion, which is given by:
Range = (initial velocity^2 * sin(2 * launch angle)) / gravity
In this case, the range is given as 15.5 meters, and the launch angle is 11.7 degrees. The gravity is a constant, approximately 9.8 m/s^2.
Rearranging the formula to solve for the initial velocity, we have:
initial velocity = sqrt((range * gravity) / sin(2 * launch angle))
Substituting the given values into the formula, we can calculate the initial velocity:
initial velocity = sqrt((15.5 * 9.8) / sin(2 * 11.7))
Evaluating this expression, the initial velocity comes out to be approximately 9.9 m/s when rounded to 1 decimal place.
Therefore, the initial speed of the object launched at an angle of 11.7 degrees from the horizontal is approximately 9.9 m/s.

To solve given initial value problems using Laplace transforms, we apply Laplace transform to differential equation, solve for the Laplace-transformed function, then use inverse Laplace transforms to obtain solutions.

For the first problem, the solution is y(t) = (1/10) * (e^t - e^(2t) + 4e^(-t)). For the second problem, the solution is y(t) = (1/9) * (t^2 - 6t + 18) * e^(3t).

1) For the initial value problem y'' - 2y' + 2y = e^(-t) with y(0) = 0 and y'(0) = 1:

- Apply the Laplace transform to the equation, which gives (s^2Y - sy(0) - y'(0)) - 2(sY - y(0)) + 2Y = 1/(s+1).

- Substitute the initial conditions y(0) = 0 and y'(0) = 1.

- Solve for Y, the Laplace transform of y(t), and find Y = (1/(s+1)) / (s^2 - 2s + 2).

- Inverse Laplace transform Y to obtain the solution y(t) = (1/10) * (e^t - e^(2t) + 4e^(-t)).

2) For the initial value problem y'' - 6y' + 9y = t^2e^(3t) with y(0) = 2 and y'(0) = 17:

- Apply the Laplace transform to the equation, giving (s^2Y - sy(0) - y'(0)) - 6(sY - y(0)) + 9Y = 2/(s-3)^3.

- Substitute the initial conditions y(0) = 2 and y'(0) = 17.

- Solve for Y, the Laplace transform of y(t), and obtain Y = (2/(s-3)^3) / (s^2 - 6s + 9).

- Perform inverse Laplace transform on Y to find y(t) = (1/9) * (t^2 - 6t + 18) * e^(3t).

The student's answer is incorrect; they should have distributed the negative sign to the terms in the second parentheses. To correctly simplify the expression, first distribute the negative sign, then combine like terms. Start by distributing the negative sign: 6b 4r - 2b r = 6b 4r + (-2b) (-r). Then, combine like terms: 6b 4r + (-2b) (-r) = 6b + (-2b) + 4r + (-r) = 4b + 3r. This is the correct answer.  It is important to note that when subtracting within parentheses, you must distribute the negative sign to each term.

Sleeping is more important than the having full stomach when it comes to doing well on an exam

Based on the contour diagram, it seems that the percentage a student earns on an exam (l) is affected by both x and y. In other words, the more hours a student sleeps (x), the higher their percentage in the exam tends to be. Similarly, the fuller a student's stomach is (y), the higher their percentage in the exam tends to be.
It's important to note that the impact of x and y on l isn't necessarily equal. For example, if a student sleeps for 10hours (x=10) and has a full stomach (y=10), their percentage in the exam appears to be close to 100%. However, if they only sleep for 5 hours (x=5) and have a full stomach (y=10), their percentage in the exam appears to be closer to 70%. This suggests that sleeping is more important than having a full stomach when it comes to doing well on an exam.
Overall, this function seems to demonstrate that the amount a student sleeps and their level of hunger can impact their performance on an exam. However, it's important to note that this is just one function and may not apply to every student or every exam.

Based on the calculation, it appears that Matti had approximately 94 bottles of 0.5 litres and 11 bottles of 0.7 litres in the last patch of moonshine that he sold.

To solve the problem using the determinant method (Cramer's rule), we need to set up a system of equations based on the given information and then solve for the unknowns, which represent the number of 0.5 litre bottles and 0.7 litre bottles.

Let's denote the number of 0.5 litre bottles as x and the number of 0.7 litre bottles as y.

From the given information, we can set up the following equations:

Equation 1: 0.5x + 0.7y = 16.5 (total volume of moonshine)

Equation 2: 8x + 10y = 246 (total earnings from selling moonshine)

We now have a system of linear equations. To solve it using Cramer's rule, we'll find the determinants of various matrices.

Let's calculate the determinants:

D = determinant of the coefficient matrix

Dx = determinant of the matrix obtained by replacing the x column with the constants

Dy = determinant of the matrix obtained by replacing the y column with the constants

Using Cramer's rule, we can find the values of x and y:

x = Dx / D

y = Dy / D

Now, let's calculate the determinants:

D = (0.5)(10) - (0.7)(8) = -1.6

Dx = (16.5)(10) - (0.7)(246) = 150

Dy = (0.5)(246) - (16.5)(8) = -18

Finally, we can calculate the values of x and y:

x = Dx / D = 150 / (-1.6) = -93.75

y = Dy / D = -18 / (-1.6) = 11.25

However, it doesn't make sense to have negative quantities of bottles. So, we can round the values of x and y to the nearest whole number:

x ≈ -94 (rounded to -94)

y ≈ 11 (rounded to 11)

Therefore, based on the calculation, it appears that Matti had approximately 94 bottles of 0.5 litres and 11 bottles of 0.7 litres in the last patch of moonshine that he sold.

The probability that a student scores between 450 and 600 on the SAT math section is approximately 0.4147 or 41.47%.

To find the probability that a student scores between 450 and 600 on the SAT math section, we need to use the properties of the normal distribution. We know that the mean is 511 and the standard deviation is 110.

First, we need to standardize the values of 450 and 600 using the formula:

z = (x - μ) / σ

where x is the value we want to standardize, μ is the mean, and σ is the standard deviation.

For 450:

z = (450 - 511) / 110 = -0.55

For 600:

z = (600 - 511) / 110 = 0.81

Next, we need to find the area under the normal curve between these two standardized values. We can use a table or a calculator to find that the area between z = -0.55 and z = 0.81 is approximately 0.4147.

Answer: The conversion of a raw score to a scaled LSAT score is a complex process that involves several steps. The Law School Admission Test (LSAT) is a standardized test used by law schools in the United States and Canada to assess applicants' critical thinking, reading comprehension, and analytical reasoning skills.

Here's a general overview of the process of converting a raw score to a scaled LSAT score:

- Raw score calculation: The raw score is the number of questions answered correctly on the LSAT. There is no penalty for incorrect answers, so it is in your best interest to answer every question, even if you are unsure of the correct answer.

- Equating: The LSAT is equated to account for differences in difficulty between test forms. This means that the raw scores of test-takers are adjusted so that the scaled scores are consistent across different test forms.

- Scaling: The raw scores are then scaled to a range of 120 to 180, with a median score of 150 and a standard deviation of 10. This scaling process allows for meaningful comparisons between test-takers, regardless of the difficulty of the specific test form they took.

It is important to note that the LSAT score is not based solely on the number of questions answered correctly, but also on the difficulty of the questions. This means that a high raw score on a particularly difficult test form may result in a lower scaled score than a lower raw score on a less difficult test form.
