What are the 3 methods to find the mean?

Answers

The three methods to find the mean are arithmetic, geometric and harmonic .

The arithmetic mean method: This method involves adding up all the values in the set and dividing by the total number of values. This gives the average value of the set.The geometric mean method: This method involves finding the product of all the values in the set and taking the square root of that product. This gives the average value of the set when the values represent quantities that are multiplied together (such as interest rates or growth rates).The harmonic mean method: This method involves taking the reciprocal of each value in the set (1/value), adding those reciprocals up, and taking the reciprocal of that sum. This gives the average value of the set when the values represent quantities that are inversely related (such as speeds or rates).

What exactly does the term "counter map" mean?

The geographic mapping used as a form of activism against prevailing power systems is known as counter-mapping.

How Do You Interpret Contour Lines on a Map?

Contour lines are described as the faint lines drawn on a map that link places of equal height above sea level. This indicates that even if you followed a contour line physically, the elevation (height of the land) would stay constant.

According to the contour map, the contour lines indicate that the coordinate (2, 1) in the x-direction has a value of 10.

Therefore;   fx(2, 1) = 10

Using the same idea, we can deduce from the attached contour map that the coordinate (2, 1) in the y-direction will have a value between 0 and 6. Therefore;

Average = (0 + 6) divided by 2 = 3

Thus;   fy(2, 1) = 3

Is the equation 3x² 11x 10 0 a quadratic equation?

Answers

Yes , the equation 3x² + 11x + 10 = 0 is a quadratic equation and the roots are x = -5/3 and x = -2

What is Quadratic Equation?

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c = 0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

where ( b² - 4ac ) is the discriminant

when ( b² - 4ac ) is positive, we get two real solutions

when discriminant is zero we get just one real solution (both answers are the same)

when discriminant is negative we get a pair of complex solutions

Given data ,

Let the equation be represented as A

Now , the value of A is

3x² + 11x + 10 = 0   be equation (1)

Now , the equation is of the form ax² + bx + c = 0 , where the value of a = 3 , b = 11 and c = 10

So , the coefficient a is has the variable x² and equation 3x² + 11x + 10 = 0 is a quadratic equation

The roots of the quadratic equations are

x = [ -b ± √ ( b² - 4ac ) ] / ( 2a )

Substituting the values in the equation , we get

x = [ -11 ± √ ( ( 11 )² - 4 ( 3 ) ( 10 ) ) ] / 2 ( 3 )

On simplifying the equation , we get

x = [ -11 ± √ ( 121 - 120 ) ] / 6

x = ( -11 ± 1 ) / 6

So , the two roots of the equations are

x = ( -11 - 1 ) / 6 and

x = ( -11 + 1 ) / 6

x = -2 and

x = -5/3

Therefore , the values of x are -5/3 and -2

Hence , the roots of the quadratic equations are -5/3 and -2

How do you prove SSS and SAS?

Answers

The triangles are congruent if all three sets of comparable sides are present. The side-side-side shortcut is a congruence technique (SSS).

Triangles are considered congruent by SAS if their two sides match up with their corresponding two sides on the other triangle, and if their included angles match up in both triangles.

We can prove two triangles, either by SSS or SAS by simply taking two triangles and checking whether the sides and the angles of the corresponding triangles are congruent or not.

By simply comparing it on the basis of their sides and angles we can easily prove the corresponding triangles by SSS or SAS.

What is the slope y =- 5x 3?

Answers

Parallel lines are two straight lines that never cross. For this to happen, the lines have to have the same slope.

In this case, the equation given is in what's called "slope-intersect" form. The general form of the slope intercept formula is y=mx + b where m is the slope of the line and b is the point on the Y-axis where the line crosses.

The equation given is y=5x+3 and since the 5 is in the place of m from the general equation, 5 is the slope. Since parallel lines have the same slope, 5 is the answer.

Slope-Intercept Form:

When we're given a linear equation we can immediately see if it's in the slope-intercept form if it follows the format  y=mx+b. As long as y does not have a coefficient the slope and y-intercept are the values of m and b.

What is the ratio?

An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0.

For instance, you could express the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls) There are 1 in 4 boys and 3 in 4 girls.

So, let n be the number of victories so that:

n/2n = 1/2 and n+3/2n+4 > 503/1000

Now, cross multiply as follows:

1000n + 3000 > 1006n + 2012

Are isosceles triangles equal to 180?

Answers

Yes, the isosceles triangles are equal to 180 degrees.

We know that isosceles triangles are triangles which have two equal sides. Since the sides are equal, they subtend equal angles as well.

However, the two equal angles subtended by the equal sides and one more angle which is subtended by the third side of the isosceles triangle all add up to a total of 180 degree as we know that the sum of all the angles of a triangle is always equal to 180 degrees.
