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:
Area = (1/2) * a * c * sin(B)
Area = (1/2) * 2 * 4 * sin(47)
Area ≈ 2.58 square yards

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.

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.

What is complete the square formula?
Completing the square is a mathematical technique used to manipulate quadratic equations into a standard form that makes them easier to solve
The general form of a quadratic equation is:
ax^2 + bx + c = 0
To complete the square, you need to add and subtract (b/2a)^2 to the left side of the equation. This is because (b/2a)^2 is equal to (b/2a) times itself, which means it is a perfect square.
Here is the formula for completing the square:
ax^2 + bx + c = 0
ax^2 + bx = -c
a(x^2 + (b/a)x) = -c
a(x^2 + (b/a)x + (b/2a)^2 - (b/2a)^2) = -c
a(x + b/2a)^2 = -c + (b/2a)^2
The equation is now in the standard form:
a(x + b/2a)^2 = (4ac - b^2)/4a
By taking the square root of both sides, you can solve for x:
x = (-b +/- sqrt(b^2 - 4ac))/2a
This is the quadratic formula, which gives you the values of x that make the equation equal to zero.

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.

Step-by-step explanation:
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 a rectangle?
The internal angles of a rectangle, which has four sides, are all exactly 90 degrees. At each corner or vertex, the two sides come together at a straight angle. The rectangle differs from a square because its two opposite sides are of equal length. A quadrilateral with parallel sides that are equal to one another and four equal vertices is known as a rectangle. It is also known as an equiangular quadrilateral for this reason.
Rectangles can also be referred to as parallelograms because their opposite sides are equal and parallel.
The given figure is a rectangle.
The angle 3 = 18°
This is because they are alternate angles.
In triangle ADC,
∠DAC = 180 - ( 18 + 90) = 72°
The angles ∠DAC and ∠BCE are alternate angles.
∠BCE and 1 are congruent angles.
1 = 72°
2 = 180 - ( 72+72) = 36°
From triangle BDC,
∠CDE = 180 - (72+90) = 18
So 4 = 180 - ( 3+∠CDE ) = 180 - (18+18) = 144°

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):
