A three-term expression is called a trinomial.

Math is a powerful tool that can be used to solve a range of problems. From simple arithmetic to complex equations, math provides us with powerful tools to explore the world around us. One such tool is the trinomial, a three-term expression that can be used to represent a wide variety of mathematical problems. In this essay, we will explore the possibilities of trinomials, examining their structure, uses, and potential applications.

Trinomials are composed of three terms: a variable, a coefficient, and a constant. Each term can be used to represent a different aspect of a problem. The variable is typically either an x or a y, and is used to represent the unknown quantity in an equation. The coefficient is a number used to modify the variable, and the constant is a number that is not affected by the variable. Together, these three terms form a trinomial, which can be used to represent a wide range of mathematical problems.

AAA ( Angle - Angle - Angle) congruence rule is one of congruence postulate but not preferable, for showing the similarity in two triangles

Two triangles are said to be congruent if one can be superimposed on the other exactly by rigid body motion, and the congruence theorem gives the conditions under which this occurs.

AAA Congruence rule:

It is stands for angle-angle-angle Congruence rule. When all three angles of one triangle is equals to the corresponding angles of another triangle. but it is possible if and only if the corresponding sides of both triangles are equal and when all three sides of two triangles are equal to each other then we use SSS Congruence rule. So, it not considered as preferable congruence rule . For example, In ∆ABC and ∆PQR

The mean formula in statistics for a set is defined as the sum of the observations divided by the total number of observations.

One of the most significant and often employed metrics of central tendency is the mean. In mathematics, there are various different kinds of means. In statistics, the mean is the product of all the values in a set of data divided by the total number of values in the data for a particular set of observations.

To put it another way, calculating the mean of a data set only requires adding up all the values and dividing the result by the total number of values.

However, depending on whether grouped or ungrouped data is provided, the basic approach and formulae change. Ungrouped data is a collection of random observations, whereas grouped data is a collection of individual observations of a variable aggregated into separate groups.

To put it another way, all that is necessary to determine the mean of a set of data is to sum up all the values and divide the total by the number of values.

However, the fundamental approach and equations vary according on whether grouped or ungrouped data are presented. Ungrouped data is a collection of arbitrary observations, whereas grouped data is a collection of distinct groupings of individual observations of a variable.

Answer:

the result of subtracting (3x^3 −2x^2 +6x−1) from the sum of (2x^3 −3x+2) and (5x^2 +4x−6) is −x^3 +3x^2 +7x−5.

Step-by-step explanation:

To find the result of subtracting (3x^3 −2x^2 +6x−1) from the sum of (2x^3 −3x+2) and (5x^2 +4x−6), we can first add the two given expressions to find the sum, and then subtract the third expression from that sum.

The sum of (2x^3 −3x+2) and (5x^2 +4x−6) is:

(2x^3 −3x+2) + (5x^2 +4x−6) = 2x^3 +5x^2 −3x+4x −6 = 2x^3 +5x^2 +x−6

Subtracting (3x^3 −2x^2 +6x−1) from this sum gives us:

(2x^3 +5x^2 +x−6) − (3x^3 −2x^2 +6x−1) = (2x^3 −3x^3) + (5x^2 −2x^2) + (x+6x) − (−1−6) = −x^3 +3x^2 +7x−5

Therefore, the result of subtracting (3x^3 −2x^2 +6x−1) from the sum of (2x^3 −3x+2) and (5x^2 +4x−6) is −x^3 +3x^2 +7x−5.

You can tell how skewed the data is by looking at the standard deviation. It gauges how far away from the mean each observed value is.

                      Any distribution will have roughly 95% of its values within two standard deviations of the mean. Think about the following data: 2, 1, 3, 2, 4. The average and the sum of squares representing the observations' variances from the mean will be 2.4 and 5.2, respectively.

Variance is simply the square of the standard deviation (v=σ2) .

The Median of 23 will be 23.

How to calculate the Median?

A data set's median value is the point where 50% of the data points have values that are lower or equal to it, and 50% of the data points have values that are higher or equal to it. In a list of odd numbers, one would select the middle number with an equal number of numbers on either side of it to determine the median value. The numbers should be arranged in order, typically from lowest to highest, before calculating the median.

The middle pair must be identified, added, then divided by two in order to calculate the median value in a list of even integers. Once more, group the figures from lowest to highest.

The median will be the average of the two middle numbers, in our questions 23 and 23, the mean of which is 23 because there are an even number of values.

Test value for a test of the difference between these two population proportions would be 2.44

What is Proportion?

A proportion in math is when two ratios are equivalent, that means they are equal to each other.

To calculate the test value for the difference between the two population proportions, you will need to first calculate the sample proportions for each group.

The sample proportion for the group of students attending 2-year colleges is 105/300 = 0.35.

The sample proportion for the group of students attending 4-year universities is 20/225 = 0.089.

Next, you can use these sample proportions to calculate the test value using the following formula:

      test value =  [tex]\frac{p1-p2}{\sqrt{[(p1(1-p1)/n1) + (p2(1-p2)/n2)]} }[/tex]

where p1 is the sample proportion for the first group, p2 is the sample proportion for the second group, n1 is the sample size for the first group, and n2 is the sample size for the second group.

Plugging in the values from the problem, we get:

test value = [tex]\frac{(0.35 - 0.089)}{\sqrt{[(0.35(1-0.35)/300) + (0.089(1-0.089)/225)]} }[/tex]

Simplifying this expression gives us a test value of approximately 2.44. This is the test value for the difference between the two population proportions.

Answer:

Elga is 22 years old

Step-by-step explanation:

Let A = Alvin's age

Let E = Elga's age

We have the equations:

A = E - 11

A + E = 33

Substitute A = E - 11 from the first equation into the second equation and solve for E

So, we have

A + E = 33

(E - 11) + E = 33

2E - 11 = 33

2E = 44

E = 22 years old

So, Alvin is 11 years old and Elga is 22 years old

Multiplicity of 3 is the number of times that the value 3 appears as a root of an equation  is the multiplicity of 3 is 3

Multiplicity of 3 (also known as a 3-fold root) is a mathematical concept used to describe the number of times a certain value appears as a root (or solution) of an equation. Specifically, it refers to the number of times a certain value appears as a root of a given equation when the equation is solved.

For example, the equation x2 = 9 has three solutions: x = 3, -3, and 0. This means that the multiplicity of 3 is 3, because 3 appears three times as a root of the equation. The general formula used to calculate the multiplicity of a given root is:

Multiplicity of x = Number of times x appears as a root of the equation

In this case, the multiplicity of 3 is 3, because 3 appears as a root of the equation three times. Similarly, if there are two solutions, x = -2 and x = 0, the multiplicity of -2 is 2, because -2 appears as a root of the equation twice.

In summary, multiplicity of 3 is the number of times that the value 3 appears as a root of an equation when the equation is solved. In the example above, the multiplicity of 3 is 3.
