At 100°C, the nitrogen molecules in the container have an rms speed of 576 m/s. The pressure inside the container,

which is at a pressure of 2.4 atm, is a result of the collisions of these fast-moving molecules with the walls of the container. The area of the wall is 13 cm x 13 cm, which means there is a total surface area of 169 cm^2.

The collisions of the nitrogen molecules with this surface area will result in a force on the wall, which is what creates the pressure.

Overall, the properties of the nitrogen molecules, including their speed and number, contribute to the overall pressure inside the container.

The expected value of W is Php 4.96. This means that on average, a person who buys a 20-peso raffle ticket from a total of 1000 tickets has a chance to gain Php 4.96 from the raffle.

To find the expected value of W, we need to calculate the probability of each possible outcome and multiply it by its corresponding value.

The cost of a ticket is Php 20, and there are 1000 tickets sold, so the total revenue is 1000 x 20 = Php 20,000.

The probability of winning the raffle is 1/1000, and the prize money is Php 5000. So, the value of W in this case is 5000 - 20 = Php 4980.

The probability of losing the raffle is 999/1000, and the value of W in this case is -20.

So, the expected value of W can be calculated as follows

E(W) = (1/1000) x 4980 + (999/1000) x (-20)

E(W) = 4.98 - 0.02

E(W) = 4.96

Therefore, the expected value of W is Php 4.96.

First, we need to convert feet to miles and seconds to hours.

1 mile is equal to 5280 feet.

So, 1716 feet is equal to (1716/5280) miles or 0.325 miles.

1 hour is equal to 3600 seconds.

So, 3 seconds is equal to (3/3600) hours or 0.00083333 hours.

Now we can calculate the speed of the plane in miles per hour by using the formula:

Speed (in miles per hour) = Distance (in miles) / Time (in hours)

Speed = 0.325 miles / 0.00083333 hours

Speed = 390 miles per hour (rounded to the nearest whole number)

Therefore, the speed of the plane is 390 miles per hour.

Step-by-step explanation:

Total number of possible outcomes on one spin = 9.

Total of non multiples of 3:

1, 2, 4, 5,7 and 8

= 6

Answer is 6/9 = 2/3.

Answer:

B. 2/3

Step-by-step explanation:

Probability is written like a fraction where on the bottom you have ALL the possibilities. There's 9 numbers on the spinner, so there's a total of 9 different ways for it to land.

9 ways total. That goes on the bottom of the fraction.

On top of the fraction you put however many number of ways the event in question can happen. That goes on top.

A multiple of three is 3, 6, 9. There are 3 ways the spinner can land on a multiple of three. So there are 6 ways to land on NOT a multiple of three (1, 2, 4, 5, 7, 8) 6 ways, so 6 goes on top.

6/9 is the answer. But always simplify fractions first, like you do.

6/9 simplifies to 2/3

The correlation between the distance a student sits from the front of the room and their grades in the course is a negative correlation.

Negative correlation is a type of correlation where one variable increases while the other variable decreases. In this case, as the distance of a student in the class increasing, the grades of the student in decreasing.

This shows that distance and grades may not correlate favorably. The professor's discovery of a negative association may therefore reflect the reality that students become less attentive as they grow farther away from their teachers.

Step-by-step explanation:

we know formula for volumne of cylinder

pie × square of radius × height

that is = 3.14× 8^2 × 23

that is = 577.76

The amount of mesh required is: 1686.24cm²

The volume is: 5934.66cm³cm³

To calculate the amount of mesh we say

L = πrℓ

where r is the radius of the base, ℓ is the generatrix, and π is approximately 3.14.

Given the diameter of the cone, we can calculate the radius as follows

r = d/2 = 22/2 = 11 cm

We are also given that the generatrix ℓ is 48 cm.

Therefore, the lateral surface area of the cone i is

L = πrℓ = 3.14 x 11 x 48 = 1657.92cm²

To find the volume of the cone, we can use the formula

V = (1/3)πr²h

where h is the height of the cone.

We can use the Pythagorn theorem to find the height of the cone as shown below

h² = ℓ² - r²

h² = 48² - 11²

h² = 2197

h = √2197

h ≈ 46.86 cm

Now we can find the volume of the cone whic is

In the simplex method, choosing the pivot row involves selecting a row with a negative value in the right-hand column and dividing the elements in the last column by the corresponding elements in the selected row to obtain the ratios. The row with the smallest non-negative ratio is then chosen as the pivot row.

By choosing the pivot row in this way, we ensure that the new solution will still be feasible, meaning that all the constraints will still be satisfied. This is because choosing the smallest non-negative ratio ensures that the new solution will not violate any of the non-negativity constraints.

Therefore, requiring that the ratio associated with the pivot row be the smallest non-negative number is an important step in the simplex method to ensure that the iteration will not take us from a feasible point to a non-feasible point.

Step-by-step explanation:

This statement is true when using the simplex method to solve a linear programming problem.

In the simplex method, we start with a feasible solution and iteratively improve it until we reach an optimal solution. At each iteration, we choose a pivot row and a pivot column to pivot around. The pivot row is chosen based on the ratio of the right-hand side value to the coefficient of the entering variable in that row. This ratio is called the pivot ratio.

Choosing the pivot row with the smallest non-negative pivot ratio ensures that we pivot to a new feasible solution. This is because the pivot row represents a constraint in the linear programming problem, and the pivot ratio represents how much we can increase the value of the entering variable while still satisfying that constraint. If the pivot ratio is negative, it means that increasing the entering variable would violate the corresponding constraint, and so we cannot pivot in that direction.

Therefore, by choosing the pivot row with the smallest non-negative pivot ratio, we ensure that we pivot in a direction that preserves feasibility and does not take us to a non-feasible point.

The correct option is D, Per the Central Limit Theorem the mean of the sampling distribution of the sample mean is equal to the population Mean.

The Central Limit Theorem (CLT) is a fundamental concept in probability theory and statistics. It states that if you take repeated random samples of a population, the sample means will follow a normal distribution, regardless of the shape of the population distribution, provided the sample size is large enough. This means that as the sample size increases, the sample mean becomes more and more normally distributed.

The CLT is important because it helps us to understand the properties of large samples, even when the population is not normally distributed. It is used in many areas of research, including social sciences, finance, engineering, and more. The theorem provides a powerful tool for estimating population parameters, such as the mean or variance, and for testing hypotheses about them. It also helps to explain why the normal distribution is so commonly observed in real-world data, and why it is often used as a model for statistical analysis.

The coordinates of R'' after the translation and dilation are (6, 12).

The translation (x, y) → (x + 1, y - 1) shifts the point R(1, 5) to the point R'(2, 4) by adding 1 to the x-coordinate and subtracting 1 from the y-coordinate.

The dilation with scale factor 3 centered at the origin multiplies the coordinates of R' by 3, resulting in:

R''(32, 34) = R''(6, 12)

To find the area of the tile, we need to first find the length of the top horizontal side.

Using the Pythagorean theorem, we can find the length of the diagonal:

d² = 3² + (5+6)²

d² = 9 + 121

d = √130

Now we can use the fact that the diagonal cuts the rectangle into two right triangles to find the length of the top horizontal side:

5x = 3(6)

x = 18/5

Therefore, the length of the top horizontal side is 18/5 centimeters.

Now we can find the area of the tile:

A = (3 + 18/5) * 5/2

A = 15 + 27/5

A = 102/5

Rounding to one decimal place, we get:

A ≈ 20.4 cm²
