you can compare two marginal distributions to see if the corresponding two variables are related. true/false
True. Comparing two marginal distributions can show if the corresponding two variables are related. This can be done by calculating the correlation coefficient of the two variables.
The correlation coefficient is a numerical measure of the degree of the linear relationship between two variables and can be calculated by dividing the covariance of the two variables by the product of their standard deviations. The correlation coefficient ranges from -1 to 1, where -1 indicates a perfect negative correlation, 0 indicates no correlation and 1 indicates a perfect positive correlation.
If the correlation coefficient is close to zero, then the two variables are not significantly related. If the correlation coefficient is close to -1 or 1, then it can be inferred that the two variables are related.

What is variance in statistics?
Variance in statistics is the squared difference between a random variable's expected value and its mean value.
Data points' variance from the mean is a measure of how they vary. A variance, according to Layman, is a measurement of how widely apart a set of data (numbers) are from their mean (average) value.
Finding the expected difference of deviation from the actual number is what is meant by variance. As a result, variance is influenced by the data set's standard deviation.
Data is more dispersed from its mean the higher the variance value, and less dispersed from mean if the variance value is low or minimal. As a result, it is referred to as a measure of data spread from mean.

Create a dice rolls application that displays 5 rolls of two dice java exercise 14
Below is the code required to Create a dice rolls application that displays 5 rolls of two dice in Java.
Here is a Java program that displays 5 rolls of two dice:
import java.util.Random;
public class DiceRolls {
public static void main(String[] args) {
Random random = new Random();
int rolls = 5;
for (int i = 0; i < rolls; i++) {
int die1 = random.nextInt(6) + 1;
int die2 = random.nextInt(6) + 1;
int sum = die1 + die2;
System.out.println("Roll " + (i+1) + ": " + die1 + " + " + die2 + " = " + sum);
}
}
}
Explanation:
We start by importing the Random class from the java.util package, which we will use to generate random numbers for the dice rolls.We then create an instance of the Random class using the new operator.We set the number of rolls we want to display to 5 using an integer variable rolls.We then use a for loop to generate and display each roll.Inside the loop, we generate two random numbers between 1 and 6 (inclusive) using the nextInt method of the Random class, and store them in the die1 and die2 variables.We then compute the sum of the two dice rolls and store it in the sum variable.Finally, we display the roll number (i+1), the individual rolls of each die, and the sum of the two dice rolls using System.out.println() method.For more such questions on Java: brainly.com/question/30354647

A thermos in the shape of a cylinder will be filled with hot chocolate. if the thermos has a radius of 4 inches and is 12 inches tall, which formula could be used to find the number of cubic inches of hot chocolate needed to completely fill this thermos?
Using the volume formula the number of cubic inches of hot chocolate needed to completely fill the thermos is 192π.
What is volume?
Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.
The formula to find the volume of a cylinder is -
Volume = πr²h
where π is pi (approximately 3.14159), r is the radius of the base of the cylinder, and h is the height of the cylinder.
In this case, the radius of the cylinder is given as 4 inches and the height is given as 12 inches.
So we can use the formula above to find the volume of the thermos -
Volume of thermos = π x (4 inches)² x 12 inches
= π x 16 square inches x 12 inches
= 192π cubic inches
Therefore, volume for thermos is 192π.

16. A farmer wants to build a rectangular pasture that has an area represented by 20x6y5. He has
enough room for the length to be 5x³y4. How wide would he need to make the pasture?
The width he need to make the pasture with the given rectangle is 4x³y⁶.
How does area of a rectangle, and its length and width are related?
Area of a rectangle is the product of its length and width.
If a rectangle has length L units and width of W units, then
Area = L × W squared units.
We are given that;
Area= 20x6y5
Length= 5x³y4
We can start by using the formula for the area of a rectangle:
Area = length x width
We know that the area of the rectangular pasture is 20x6y5, and we know the length is 5x³y4. So we can plug in these values and solve for the width:
20x6y5 = (5x³y4) x width
To solve for width, we can divide both sides by 5x³y4:
width = 20x6y5 / (5x³y4)
Simplifying the expression on the right-hand side, we can divide each term in the numerator by 5x³y4:
width = (4x³y¹) x (4y5)
Simplifying further, we can add the exponents of the common factor y:
width = 4x³y⁶
Therefore, the farmer would need to make the width of the rectangular pasture will be 4x³y⁶.

75% of 500 is determined using bar model as 375.
How to use bar model to find 75% of 500?
To use a bar model to find 75% of 500, you can follow these steps:
Draw a bar to represent the whole quantity, which in this case is 500.Divide the bar into four equal parts, as there are four parts in 100%, since 75% is 3/4 of 100%, each part will represent 25%.Shade in three of the four parts to represent the 75% you are trying to find.Count the number of shaded parts. In this case, you shaded three of the four parts.Use the bar model to calculate the value of the percentage. Since each part represents 25% of the whole quantity, and you shaded three parts, the value of the percentage you are looking for is:3 parts x 25% per part = 75%
Finally, to find the value of 75% of 500, you can multiply 500 by 75% in decimal form (0.75):
500 x 0.75 = 375

how to convert 0.02 btc to usd?
0.02 Bitcoin is in dollar is 497.928000 US Dollar (USD)
1 Bitcoin = 24872.70 US Dollar (USD)
so 0.02 bitcoin in dollar is
0.02 * 42872.70 = 497.928000 US Dollar (USD)
Bitcoin has a high inverse correlation with the US Dollar Index (DXY). This makes conceptual sense as it has a fixed supply and is most commonly traded against the US dollar more than any other currency. Now, looking at the weekly data from early 2018, the correlation is around -70% (R2 is 0.5877).
Volker successfully curbed the extreme inflation of the late 1970s and early 1980s with aggressive monetary policy, pushing the dollar to a very high level. Like today, the U.S. hasn't experienced similarly high levels of inflation and may have already peaked. As a result, the US dollar is unlikely to hit her early 1980s highs.

Find the area of the triangle having the given measurements
B=47 degree
, a=2 yards, c=4 yards
herefore, the area of the triangle is approximately 2.58 square yards.
Area = (1/2) * a * c * sin(B)
where B is the angle opposite to the side of length b, and a and c are the lengths of the other two sides.
In this case, we have:
B = 47 degrees (given)
a = 2 yards (given)
c = 4 yards (given)
To use the formula, we first need to find the length of the third side, b, using the Law of Cosines:
[tex]b^{2}[/tex] = [tex]a^{2}[/tex]+ ^[tex]c^{2}[/tex] - 2accos(B)
b^2 = 2^2 + 4^2 - 224cos(47)
b^2 ≈ 13.37
b ≈ 3.657
Now we can substitute the values into the formula for the area:

how to convert millimolar to molar
One of the molar concentration units is the millimolar. The symbol or abbreviation mM stands for millimolar. 1 millimolar equals 1 mol/meter³ in terms of measurement units. In terms of molar, 1 millimolar is equivalent to 0 point 001 molar.
The term "molar concentration" (also known as "molarity," "amount concentration," or "substance concentration") refers to the amount of a substance per unit volume of solution and is used to describe the concentration of a chemical species, specifically a solute, in a solution.
The number of moles per liter, denoted by the unit symbol mol/L or mol/dm3 in SI units, is the most widely used unit for molarity in chemistry. One mol/L of a solution is referred to as one molar, or 1 M.
Because most solutions' volumes only slightly vary with temperature due to thermal expansion, the use of molar concentration in thermodynamics is frequently inconvenient. Typically, temperature correction factors are introduced to solve this issue, or a concentration measure that is not temperature dependent, like molality, is used.
