What is mass?Mass, in physics, quantitative measure of inertia, a fundamental property of all matter. It is, in effect, the resistance that a body of matter offers to a change in its speed or position upon the application of a force. The greater the mass of a body, the smaller the change produced by an applied force. The unit of mass in the International System of Units (SI) is the kilogram, which is defined in terms of Planck’s constant, which is defined as equal to 6.62607015 × 10−34 joule second. One joule is equal to one kilogram times metre squared per second squared. With the second and the metre already defined in terms of other physical constants, the kilogram is determined by accurate measurements of Planck’s constant.To learn more about International System of Units (SI) refer to:

What is the change of variables method?
In mathematics, a change of variables is a basic technique used to simplify problems in which the original variables are replaced with functions of other variables. The intent is that when expressed in new variables, the problem may become simpler, or equivalent to a better-understood problem.
We can evaluate the triple integral by using the change of variables method. We can set u = x, v = y, and w = z, and find the corresponding bounds for each variable in terms of the original bounds.
Then, we have
∭ (x + y + z) dV = ∭ (u + v + w) det(J) du dv dw,
where J is the Jacobian matrix of the transformation and det(J) is its determinant.
We know that 0 <= x <= 3, 0 <= y <= 3, and 0 <= z <= 9 - x^2 - y^2. Therefore, we have:
u = x, 0 <= u <= 3
v = y, 0 <= v <= 3
w = z, 0 <= w <= 9 - u^2 - v^2
The determinant of the Jacobian matrix is 1, so we can simplify the integral to:
∭ (u + v + w) du dv dw = ∫(0,3) ∫(0,3) ∫(0,9-u^2-v^2) (u+v+w) dw dv du
= ∫(0,3) ∫(0,3) (u+v)(w) + (1/3)(w^3) dv du
Hence, By solving this iteratively we get the final answer as 342.

The coefficient of determination (R²) measures how well a statistical model predicts an outcome. The outcome is represented by the model’s dependent variable.
The lowest possible value of R² is 0 and the highest possible value is 1. Put simply, the better a model is at making predictions, the closer its R² will be to 1.
Suppose that you perform a simple linear regression that predicts students’ exam scores (dependent variable) from their time spent studying (independent variable).
If the R2 is 0, the linear regression model doesn’t allow you to predict exam scores any better than simply estimating that everyone has an average exam score.
If the R2 is between 0 and 1, the model allows you to partially predict exam scores. The model’s estimates are not perfect, but they’re better than simply using the average exam score.

2. Evan runs a t-shirt business. He sells shirts for $10. After selling 10 shirts, Evan has $70. Assume x represents the number of shirts sold, and y represents the profit, use this information to fill in the blanks in the statement: How much money did Evan have before he sold any shirts?
A) -$30
B) $30
C) $100
D) $0
Answers
Answer:
D
Step-by-step explanation:
The statement says that Evan sells shirts for $10 and after selling 10 shirts, he has $70. We know that the profit is the revenue (the amount of money earned) minus the costs. In this case, the revenue is the amount of money Evan earns from selling shirts and the costs are the amount of money Evan has spent on producing and buying the shirts. We can use this information to set up the equation y = 10x - c where y is the profit, x is the number of shirts sold, and c is the costs.
Given that Evan has $70 after selling 10 shirts, we can substitute 10 for x and 70 for y into the equation to get:
70 = 10(10) - c
Solving for c we get:
c = -30
This means that the costs were $30. To find out how much money Evan had before he sold any shirts we need to subtract the costs from the initial amount. Evan had $0 before he sold any shirts, so the answer is D) $0.

According to the question of equilateral triangles, 6.7√3 cm is the vertical height of the hexagon.
What is equilateral triangles?An equilateral triangle is a triangle with all three sides having the same length and all three angles measuring 60 degrees. It is one of the three basic shapes in geometry and is considered to be the most symmetrical triangle. The sides of an equilateral triangle are always congruent, meaning all three sides have the same length. The sides of an equilateral triangle are also always perpendicular, meaning all three angles are equal to 60 degrees. The area of an equilateral triangle can be calculated using the formula A = (1/2)bh, where b is the length of the base and h is the length of the height.
The vertical height of the hexagon can be calculated using the Pythagorean Theorem. The length of each side of the equilateral triangle is x/2 and the height of the triangle is x√3/2.
The total vertical height of the hexagon is therefore 6 x x√3/2, which is equal to 6.7√3 cm.

The meaning of the interval is "there has been no change in support for the candidate". Thus, option (a) is correct.
The 90% two-proportion z-confidence interval (-0.0199, 0.0510) represents the likely range of the genuine difference between the two polls in support of candidate X.
Because the interval comprises 0, the difference in support between the two polls is unlikely to be statistically significant. In other words, there is no compelling evidence that there has been a significant shift in support for the candidate.

Open MINITAB file rateMP.mpj from your email. This data represents information on 700 instructors from the popular website ratemyprofessors.com. All instructors are sampled from the Foothill-De Anza Community College District. Here is a description of the data: College: Foothill or De Anza Smiley: Positive - Neutral Negative Photo: Instructor has a photo Hot: Instructor has a chili pepper Gender: Male or Female Dept: Academic Department (example - Mathematics) Division: Academic Division (example - PSME) Num: Number of Ratings for that faculty member Overall: Average Overall Quality Rating (1-5 scale, lowest to highest) Easiness: Average Easiness Rating (1-5 scale, hardest to easiest) We are going to use Minitab to make some graphs for this data. Specifically, we are going to look at the average easiness rating of Foothill-De Anza Community College instructors, and we will use the 700 instructors as a sample. First, let's ask some questions about this data.
Answers
What is the average easiness rating of Foothill-De Anza Community College instructors? What are the distributions of easiness ratings for instructors with a photo, chili pepper, and no chili pepper? Is there a relationship between gender and easiness ratings?
To answer these questions, we first need to open the MINITAB file rateMP.mpj. Upon opening the file, we can see that it contains data on 700 instructors from Foothill-De Anza Community College, including the college they teach at, their gender, the department and division they teach in, the number of ratings they have received, their overall quality rating, and their easiness rating. To answer the first question, we can use the average function on the easiness column to find the overall average easiness rating of Foothill-De Anza Community College instructors. To answer the second question, we can use a bar chart to compare the distributions of easiness ratings for instructors with a photo, chili pepper, and no chili pepper. To answer the third question, we can use a two-way table to examine the relationship between gender and easiness ratings. After creating these graphs and tables, we can then interpret our results.

Submit your answer in scientific notation.
Answers
The result of the given expression in the scientific notation is 2.7 × 10⁻⁸.
What is the scientific notation answer?
Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10⁸.
To compute the expression (3.0 × 10⁻³)³, we can use the following steps.
Multiply 3.0 × 10⁻³ by itself three times.
The expression (3.0 × 10⁻³)³ can be calculated as follows:
(3.0 × 10⁻³)³ = (3.0)³ × (10⁻³)³ = 27 × 10⁻⁹
So the answer in scientific notation is 2.7 × 10⁻⁸.
Therefore, the answer in scientific notation is 2.7 × 10⁻⁸.

approximately where does the particle achieve its greatest possible acceleration on the interval 0 to b?
Answers
The greatest positive acceleration occurs at the midpoint of the interval, when the particle is changing velocity most rapidly.
What is velocity?
Velocity is a measure of the rate of change of an object's position over a period of time. It is a vector quantity, which means it has both magnitude (or size) and direction. Velocity is usually expressed in terms of distance traveled per unit of time, such as meters per second (m/s). Velocity can be determined by dividing the distance traveled by the time taken. For example, if an object travels 20 meters in 5 seconds, its velocity would be 4 m/s. Velocity can also be calculated by taking the derivative of the object's position with respect to time.
The particle will achieve its greatest positive acceleration at the midpoint of the interval, at t = b/2.
This is because the acceleration is greatest when the velocity is changing most rapidly.
At the beginning of the interval, the particle has zero velocity, so it has no acceleration.
At the end of the interval, the particle has reached its maximum velocity, and the rate of change of velocity is zero, so it has no acceleration. Therefore, the greatest positive acceleration occurs at the midpoint of the interval, when the particle is changing velocity most rapidly.
