Side a of a triangle =1.5cm. Side b=9.2cm. What is side c if a^2+b^2 =c^2?

Answers

Answer 1

The value of AD is  2.4cm

What is Thales Theorem?If a line drawn perpendicular to one side of a triangle intersects the other two sides at unique points, then the ratio of the other two sides is the same. His most well-known claim was that water is the basic component of everything. He thought of the world as a flat body floating in a huge ocean. Thales opened the way for the Socratic age and the ancient philosophers to provide the foundation for the main ideas of Western philosophy. One of the seven wise men, Thales of Miletos, is credited with being the first to study physical philosophy. Water, according to him, serves as both the beginning (or basic principle) and the end of all things.

We have to find [tex]$\mathrm{AD}=$[/tex] ?

Since,

[tex]$$\mathrm{DB}=7.2 \mathrm{c} . \mathrm{m} .$$[/tex]

[tex]$$\mathrm{AE}=1.8 \mathrm{c} . \mathrm{m} .$$[/tex]

[tex]$$\mathrm{EC}=5.4 \mathrm{c} \cdot \mathrm{m} .$$[/tex]

So, We know that (using Thales Theorem)

[tex]\frac{\mathrm{AD}}{\mathrm{DB}}=\frac{\mathrm{AE}}{\mathrm{CE}}[/tex]

Then,

[tex]$\frac{\mathrm{AD}}{7.2}=\frac{1.8}{5.4}$[/tex]

[tex]$\mathrm{AD}=\frac{1.8 \times 7.2}{5.4}$[/tex]

[tex]$\mathrm{AD}=\frac{7.2}{3}$[/tex]

Create a bar graph using the following data: 30 students; 10 male and 20 female

Answers

The number of peaks, symmetry, tendency to skew, and homogeneity of a distribution are all indicators of its shape.

Explain about the shape of the distribution?

There are two types of data item distributions: symmetric and asymmetric. The "normal distribution" and the "skewed distribution" are two prevalent illustrations of both symmetry and asymmetry. The distribution's two halves are mirror images of one another in a symmetrical distribution.

The number of peaks, the presence of symmetry, the propensity to skew, and the homogeneity of a distribution all help to explain its shape. (Graphs with skewed distributions show a greater number of points on one side than the other.) PEAKS: Graphs frequently show maximums or peaks in a certain area.

Either a normal distribution or a normal curve. When dealing with such a distribution, the mean should be reported.

Simple Frequency Distribution:

A simple frequency distribution is a table that lists each unique score in the data set and the number of times that score appears.

Score Frequency:

1.0 3

1.1 3

1.2 1

1.3 1

1.5 1

2.0 1

2.2 2

2.3 2

2.5 1

3.0 2

3.2 1

3.4 2

3.5 2

3.7 1

3.8 1

4.0 5

Grouped Frequency Distribution:

A grouped frequency distribution is a table that groups the scores into ranges (also known as bins) and lists the number of scores that fall into each range.

Score Range Frequency

1.0-1.9 9

2.0-2.9 7

3.0-3.9 10

4.0-4.9 4

Frequency Polygon:

A frequency polygon is a graph that is created by connecting the midpoints of the top of the bars in a histogram. The x-axis represents the scores and the y-axis represents the frequency.

Histogram:

A histogram is a graph that represents the frequency distribution of a set of continuous data. It is similar to a bar graph, but the bars are adjacent to each other and there are no spaces between the bars.

Shape of the distribution:

The shape of the distribution is right-skewed, which means that the majority of the data is concentrated on the left side of the distribution and there is a long tail of data points on the right side. This is indicated by the fact that the majority of the scores are between 1 and 3, while only a few scores are at 4.0 or above.

quadratic factoring 9x^2-8x-20

The value of the quadratic equation is A = ( 9x + 10 ) ( 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 quadratic equation be represented as A

Now , the value of A is

A = 9x² - 8x - 20   be equation (1)

On simplifying the equation , we get

A = 9x² - 18x + 10x - 20

On factorizing the equation , we get

A = 9x ( x - 2 ) + 10 ( x - 2 )

Taking the common factors in the equation , we get

A = ( 9x + 10 ) ( x - 2 )

So , when A = 0

( 9x + 10 ) = 0

x = -10/9

And , when ( x - 2 ) = 0

x = 2

Hence , the quadratic equation is A = ( 9x + 10 ) ( x - 2 )

- Find the range of the function f(a) = 5+ 1/2a when the domain is (0,4,6)

Answers

Step-by-step explanation: The range of the function is the set of all its output values. To find the range of f(a) = 5 + 1/2a when the domain is (0, 4, 6), we can substitute these values into the function and see what the output is:

f(0) = 5 + 1/2 * 0 = 5

f(4) = 5 + 1/2 * 4 = 7

f(6) = 5 + 1/2 * 6 = 8

So the range of f(a) is the set of values {5, 7, 8}.

The assumed line's and direction's parametric equation is x = 5 + t; y = -1; z = 3 -2t

How can the parametric equation be found?

The absence of points and lines renders the question insufficient.

I will therefore utilize the following presumptive parameters:

As the line traverses: (5, -1, 3)

The direction is  ~v = <1, 0, -2>

The parametric equation of the line is represented as:

r<x,y,z> = Line + t<direction>

This gives

r<x,y,z> = (5, -1, 3) + t<1, 0, -2>

Express the equation in terms of x, y and z

x = 5 + t * 1

y = -1 + 0 * t

z = 3 -2 * t

Solve the equations

x = 5 + t

y = -1

z = 3 -2t

Consequently, the assumed line's and direction's parametric equation is x = 5 + t; y = -1; z = 3 -2t

Answers

The diagonals of a parallelogram are equal in length if and only if the parallelogram is a rectangle. The sum of squares of diagonals is equal to the sum of squares of sides.

We should consider a parallelogram shape that has sides named as and .

a. The corner to corner lines of the parallelogram can be marked as and . These two inclining lines cross each other at the focal point of the parallelogram, isolating each other into halves. This implies that the two inclining lines and have a similar length.

b. Assuming the inclining lines of the parallelogram have similar length, this implies that the parallelogram is really a square shape. This is on the grounds that in a square shape, every one of the sides are equivalent long. Then again, on the off chance that the parallelogram is a square shape, its inclining lines should have a similar length.

c. We can utilize the Pythagorean hypothesis to show that the amount of the squares of the lengths of the slanting lines is equivalent to the amount of the squares of the lengths of the sides. The Pythagorean hypothesis expresses that in a right triangle, the amount of the squares of the two more limited sides is equivalent to the square of the length of the longest side (the hypotenuse). On the off chance that we view at the parallelogram as two nearby right triangles, we can apply the Pythagorean hypothesis to every triangle. This gives us two conditions, and when we add these two conditions, we observe that the amount of the squares of the lengths of the inclining lines is equivalent to the amount of the squares of the lengths of the sides.

c) The function is defined as follows: y = 0.03x² - 2.4x + 45.

How to define the quadratic function?

The quadratic function with roots x* and x** is given by the equation presented as follows:

y = a(x - x*)(x - x**)

The roots = zeros are the values of x for which the graph of the function crosses the x-axis, hence:

x* = 30, x* = 50.

Then the function is:

y = a(x - 30)(x - 50)

y = a(x² - 80x + 1500).

When x = 0, y = 45, hence the leading coefficient a is obtained as follows:

1500a = 45

a = 45/1500

a = 0.03.

Hence the definition of the function is given as follows:

y = 0.03(x² - 80x + 1500).

y = 0.03x² - 2.4x + 45.

The determinant of the 3*3 matrix A where A = [[1,2,3], [4,5,6], [7,8,9]] is zero (0).

What is the determinant of a matrix?

A matrix's determinant refers to the scalar value calculated for a given square matrix. The determinant is a concept in linear algebra, and its components are square matrixes. It may be viewed as the matrix transformation's scaling factor.

To find the determinant of the given matrix A = [[1,2,3], [4,5,6], [7,8,9]];

Choose the row or column with the most 0 elements. If there are no 0 elements choose any row or column. Multiply every element in row 1 by its cofactor and add. The cofactor is "the minor" with the sign changed if the indices match the a − position on the sign chart.

From the attached steps in the image below, the next following step would be to add the determinants;

= 1 ×(−3)−2×(−6)+3×(−3)

= -3 + 12 - 9

= 12 - 12

= 0

This process that Jillian used is called the Countermatching algorithm which is a method of adding and subtracting integers.

The Countermatching algorithm

Step 1: Jillian puts a 7 tile on the table. Step 2: She then puts a negative two tile next to the 7 tile. Step 3: Jillian then counts the total amount of tiles on the table, which is 5.Step 4: She then concludes that 7+(-2)=2. In this algorithm, each number is represented by a corresponding amount of tiles.The two integers are placed side by side and then the total amount of tiles is counted.This number is the sum of the two integers. In this example, there were five tiles in total, so the sum was two.Jillian arranges two sets of integer tiles, one with a value of 7 and one with a value of -2. She then combines the two sets of integer tiles, putting the 7 together with the -2. Jillian then counts the total number of tiles, which is 5. She then reads the result of the addition, which is 2. This process of solving an addition problem using integer tiles is called a model method. This method helps students visualize the operations they are performing, allowing them to better understand the mathematics.It is especially useful for students who may have difficulty conceptualizing math operations and helps them to more easily find the solution to the problem. In addition, the model method can also be used to solve subtraction, multiplication, and division problems.

What do you mean by probability?

Probability is a branch of mathematics that deals with the likelihood or chance of an event happening. It is a number between 0 and 1 that indicates the likelihood of an event occurring, with 0 meaning that an event is impossible and 1 meaning that an event is certain to occur.

Probability is used to model and make predictions about real-world situations such as the outcome of a coin flip, the results of a survey, or the success of a marketing campaign. It is also used in many fields including statistics, finance, engineering, and sciences to make decisions based on uncertain data.

The problem requires the use of the normal approximation to the binomial distribution to estimate the probabilities. Let X be the number of flights that arrive on time out of 186 flights. Then X follows a binomial distribution with parameters n = 186 and p = 0.88.

We can use the normal approximation to estimate the probability of X taking different values. Let's denote the mean and standard deviation of X as mu and sigma respectively:

mu = np = 186 × 0.88 = 163.68

sigma = √(np(1-p)) = √(186 × 0.88 × 0.12) = 5.55

(a) P(159) = P(X = 159) can be estimated using the normal distribution using the Z-score:

Z = (159 - mu) / sigma = (159 - 163.68) / 5.55 = -0.77

P(159) ≈ P(Z < -0.77) ≈ 0.2224 (using a standard normal table)

(b) P(X ≥ 159) can be estimated using the cumulative distribution function:

Z = (159 - mu) / sigma = (159 - 163.68) / 5.55 = -0.77

P(X ≥ 159) = P(Z ≥ -0.77) = 1 - P(Z < -0.77) = 1 - 0.2224 = 0.7776

(c) P(X < 161) can be estimated using the cumulative distribution function:

Z = (161 - mu) / sigma = (161 - 163.68) / 5.55 = -0.36

P(X < 161) = P(Z < -0.36) = 0.3545 (using a standard normal table)

(d) P(161 ≤ X ≤ 174) can be estimated using the cumulative distribution function:

Z1 = (161 - mu) / sigma = (161 - 163.68) / 5.55 = -0.36

Z2 = (174 - mu) / sigma = (174 - 163.68) / 5.55 = 1.51

P(161 ≤ X ≤ 174) = P(Z1 < Z < Z2) = P(Z < 1.51) - P(Z < -0.36) = 0.9330 - 0.3545 = 0.5785

What is a function?

A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively. Initially, functions represented the idealized relationship between two changing quantities.

Here,

We know that for any function f(x) ; x represents the independent variable i.e. the variable whose value is defined and y=f(x) denotes the dependent variable i.e. the variable whose value is defined corresponding to the independent variable.

i.e. it depends on the variable x.

Similarly here s(x) is the dependent variable since it is defined corresponding to the variable x.

Hence, The value of s(x) depends on the value of x, since s is a function of x.

"When written in reduced echelon​ form, any m×n matrix will have at least one row of all zeros. When solving Ax=b​, that row will represent an equation with a zero on the left side and a possibly nonzero entry of b on the right side."

Now, According to the question:

"Information available from the question"

Let a be a 3 x 2 matrix. explain why the equation a x b cannot be consistent for all b in.

Since a 3x2 matrix only has 2 columns, matrix A can at most have 2 pivot columns and 2 pivot positions. This cannot fill all 3 rows w/ pivots so Ax=b can't be consistent for all b in R3. If A is an m x n matrix w/ m>n then A can have at most n pivot positions which isn't enough to fill all m rows, so Ax = b can't be consistent for all b in R3.

Hence, The correct option is (A)

Both the second and the induction hypothesis result from the first inequality.

You established its validity for n=5. Let's now assume that it is true for some number n5. Its validity for n+1 is to be demonstrated. But

2n+1=2×2n>2×n2>(n+1)2.

The first discrepancy is a result of induction, and we are aware of the second (n−1)2≥42>2, since n≥5

We can widen this disparity  (n−1)2>2 as follows:

n2−2n+1>n2−2n−1>2n2−2n−1>2n2>20n2n2+2n+1=(n+1)2,

which is the second inequality claimed in (♠)

2n+1=2n∗2>2n2=n2+n2>n2+2n+1=(n+1)2

2n+1>(n+1)2

choose the first matching integer, then.

The values that make vector b a linear combination of vectors A1, A2 and A3 are given as follows:

[tex]\alpha_1 = -1.9, \alpha_2 = 1.1, \alpha_3 = 1.5[/tex]

What is a linear combintion?

A vector is a linear combination of other vectors when it can be obtained via a system of equations from the other vectors.

Considering the matrices, the system of equations to obtain the values of the variables that make vector b a linear combination of vectors A1, A2 and A3 are given as follows:

x - y = -3.2x + 3y + z = 1.x + 4y - z = 1.

Adding the second and the third equation, we have that:

3x + 7y = 2.

Since x = y - 3, the value of y is obtained as follows:

3(y - 3) + 7y = 2

3y - 9 + 7y = 2

10y = 11

y = 1.1.

Then the value of x is of:

3x = 2 - 7(1.1)

x = [2 - 7(1.1)]/3

x = -1.9.

The value of z is obtained as follows:

z = 1 - 2x - 3y

z = 1 - 2(-1.9) - 3(1.1)

z = 1.5.

In the desired notation, these values are given as follows:

[tex]\alpha_1 = -1.9, \alpha_2 = 1.1, \alpha_3 = 1.5[/tex]
