Answer:
79.31%
First we need to find the total number of students.
We do that summing all the four values in the table:
Total students = 2 + 18 + 3 + 6 = 29
Then, the students that play a sport or an instrument are all student but the ones that don't play both:
Students(sport or instrument) = 29 - 6 = 23
So the probability of a random student playing a sport or an instrument is 23/29 = 0.7931 = 79.31%

Which class is the best one to take? Also could you please explain why you chose the one that you did?
1. AP Euro
2. AP Psych
3. AP World
Answer:
AP Psych
Explanation:
In my opinion, it will take you farther in college than AP Euro or World would. You'll be suprised to find how many majors require Psychology. First, it is both a social science and biological science. If you are taking, AP bio/AP chemistry or any other science AP psych is the way to go. You go over neurotransmitters and their major functions and how relate to our behavior. I would also take this class if you have previously taken AP biology/chemistry because you will begin the class already knowing about neurotransmitters, inhibitors, and receptors. I took AP bio last year and am taking AP Psych this year and I currently have an A because I am educated on neurological functions. Even if you haven't taken bio or chemistry I would still highly suggest psychology because it prepares you for college and enhances your understanding of society and your own emotions.

The caravel was a ship used to explore the New World in the 15th and 16th Century, during the Age of Discovery. The Caravel was developed and modified from simple fishing ships to sailing ships by Portuguese to explore the African coast and the Atlantic Ocean.
The new and improved caravel made it possible for European to explore and colonize the New World. With the desire to expand their boundaries of politics, economy, religion, and science, they explored the New World using the Caravel.
Therefore, option B is correct.
Concentrated nitric acid has a molarity of 15.9 M and a density of 1.42 g/mL. Calculate the following concentrations using 1.00 L of HNO3.
a) % by mass
b) molality
c) mole fraction
Answer: a) percent by mass = [tex]70.5\%[/tex]
b) molality = 38.01mol/kg
c) mole fraction = 0.40
Explanation:
Given molarity = 15.9 M
moles of [tex]HNO_3[/tex] = 15.9 moles in 1.00 L of solution
mass of [tex]HNO_3[/tex] = [tex]moles\times {\text {Molar mass}}=15.9mol\times 63g/mol=1001.7g[/tex]
Density of solution of = 1.42 g/ml
Volume of solution = 1.00 L = 1000 ml
Mass of solution = [tex]Density\times volume= 1.42g/ml\times 1000ml=1420g[/tex]
mass of solvent = mass of solution - mass of solute = (1420-1001.7) g = 418.3 g = 0.4183 kg
moles of solvent = [tex]\frac{\text {given mass}}{\text {Molar mass}}=\frac{418.3g}{18g/mol}=23.2mol[/tex]
percent by mass =[tex]\frac{\text {mass of nitric acid}}{\text {mass of solution}}\times 100=\frac{1001.2}{1420}\times 100=70.5\%[/tex]
molality = [tex]\frac{\text {no of moles of solute}}{\text {mass of solvent in kg}}=\frac{15.9mol}{0.4183kg}=38.01mol/kg[/tex]
mole fraction = [tex]\frac{\text {moles of solute}}{\text {total moles}}=\frac{15.9}{15.9+23.2}=0.40[/tex]

mid point of 0 and 3 is 1.5, -1 to 0 is 1, so the average value over that is 1.5
then 3 to 1, mid point is 2, with a lenght of 1, so 1.
midpotni of 1 and 5 is 3, over a length of 2, so 6
5 and 8 -> 6.5, length of 2 -> 13
8 and 4 -> 6, length of 1 -> 6
4 and 9 -> 6.5, length of 1 -> 6.5

Ebecca reads a book at a rate of 1 page every 4 minutes. If her reading rate remains the same, which method could be used to determine the number of minutes for her to read 16 pages. Group of answer choices add 4 and 16 divide 16 by 4 multiply 4 by 16 subtract 4 from 16.
Answer:
Multiply 4 by 16
Explanation:
Given
[tex]Rate = 1\ page/4\ minutes[/tex]
Required
Select the method that maintains her rate for 16 pages
To get the method for 16 pages, we simply multiply 4 by 16. This is shown below
[tex]Rate = 1\ page/4\ minutes[/tex]
Calculate the unit rate
[tex]Rate = \frac{1}{4} page/min[/tex]
[tex]Rate = 0.25 page/min[/tex]
For 16 pages, it is:
[tex]Rate = \frac{16 page}{4 min * 4}[/tex]
[tex]Rate = \frac{16 page}{4 min * 16}[/tex] -- Here, we multiply 4 by 16
[tex]Rate = \frac{16 page}{64\ min}[/tex]
[tex]Rate = \frac{16}{64} page/min[/tex]
[tex]Rate = 0.25 page/min[/tex]
See that the unit rates remain the same.

Describe the process and results you used to determine the force exerted by the hockey stick on the puck.
Answer:
If you know the mass and can find the final speed of the puck, then you know how much impulse was applied to it. If you then take the known (from your video) period of time that the stick was contacting the puck, you can calculate the average force over that time.
If you want to get more sophisticated, you might be able to figure out the forces applied by looking at how the stick bends at any given instant, again from your video.

the study, those in long-term marriages were more likely to be more physically
active, at a healthy weight, and nonsmokers. Those who were not married were
about 20% more likely to be deceased. What conclusion can we draw from this

What is a number-grading system?In education, number-grading systems are systems based on numbers used to measure students' performance. There are two common systems all around the world.
1 to 10: In this system, the highest grade is 10 and the lowest grade is 1. This means a student that is given a 1 is performing poorly.1 to 5: This system is quite similar to the first system because 5, which is the highest number represents the best performance.What student is doing the best?The student that is doing the best is Julia, she got a score of 5 and therefore she is the one that has the best performance on the coursework.

impact.
O B. It must protect the environment at all costs.
OC. t must serve present society at the cost of future generations.
D. It must use only traditional farming practices.
Answer:
A. It must meet society's needs while minimizing environmental
impact.
Explanation:
Given that sustainability is the practice of utilizing and maintaining natural resources without causing defects to biodiversity balance.
Hence, for an agricultural technique to be considered sustainable "It must meet society's needs while minimizing environmental impact."
This implies that there should be a balance between natural resource exploitation and ecological balance, such that humans can enjoy both the resources and nature without one affecting the other and at the same time, with no negative effect on humans.

Warmer temperatures at the Earth's poles could change atmospheric circulation and wind patterns. Propose a solution for how communities near the poles can prepare for these changes in wind.
Warmer temperatures at the poles could alter wind patterns and atmospheric circulation.
What is atmospheric circulation?Through atmospheric circulation, heat is transferred over the surface of the Earth. This has an effect on the water cycle, including cloud formation and precipitation events. The movement of air masses determines our everyday weather, and long-term patterns in circulation have an impact on regional climate and ecosystems.
This pattern, called atmospheric circulation, is a result of the Earth being heated by the Sun more at the equator than in the poles. The rotation of the Earth has an effect on it as well. In the tropics, near the equator, warm air rises.
Atmospheric circulation, or the movement of heat and air over the earth's surface, is governed by Hadley, Ferrel, and polar cells.
Thus, Warmer temperatures at the poles could alter wind patterns.

If men were angels, no government would be necessary. . . . you must first enable the government to control the governed; and in the next place oblige it to control itself. A dependence on the people is . . . the primary control on the government.
–Federalist 51, 1788
In a national government, unless cautiously and fortunately administered, the disputes will be the deep-rooted differences of interest, where part of the empire must be injured by the operation of general law.
–A Maryland farmer, 1788
How is the first passage, taken from the Federalist papers, an example of the stance of a Federalist?
It favors state governments over the federal government.
It promotes the concept of a strong federal government.
It opposes separating powers in the federal government.
It dismisses the importance of the federal government.
Answer:
It promotes the concept of a strong federal government.
Explanation:
The first text reinforces the need to promote strong federal government. This concept was the main idea defended by the federalists and can be defended by the text when the author states that a people needs to be governed by a system that has the power to organize men, to control them in relation to their defects. The text shows that men are not angels, so it is necessary that a powerful system has the power to lead them. That powerful system is the federal government.
