(a) You and a randomly selected student from your class both earn A's in this course.

Answer: Here selection of one student is independent of the other.

Therefore it is independent.

(b) You and your class partner both earn A's in this course.

Answer: Here enough data is not available to comment whether the given event is mutually exclusive or independent.

Therefore it is neither.

(c) If two events can occur at the same time, they must be independent.

Answer: If both the events occur at the same time then it is not necessary they are independent.

Therefore it is False.

An IRRATIONAL number is a number that can't be written as a simple fraction!

What is a simple fraction? a fraction having whole numbers for the numerator and denominator. To add on that i think it also means that it can be simplified.

So we can't have a mixed number or a fraction that can't be simplified.

A. The square root of 25=5.  Can we turn five into a fraction? We sure can! It's also whole, which is a good sign too.

B. The square root of 28=5.29 We can't turn B into a simplified fraction. it will be a mixed number with  6 93/100.  ✅

C. The square root of 48=6.93 We also can't turn C into a simplified fraction. It will be a mixed number as well, looking like 5 29/100. ✅

D. The square root of 169=13.  This is promising, it's a whole number!

If we wanted to analyze the variables GNP (Gross National Product) and Region at the same time, bargraph, pie chart, one way table would be appropriate to use.

Gross national product (GNP), calculated without taking into account the depreciation or consumption of capital utilized in the manufacturing process, is the total market value of the final goods and services generated by a country's economy during a given time period (often a year).

The value of the final domestic goods and services generated inside a country's boundaries is known as the gross domestic product (GDP).

The value of all the finished goods and services that are owned by a nation's citizens, regardless of whether those kinds of goods were made in that nation, is what is known as its gross national product (GNP).

The measure of the angle is 1.0 when rounded to one decimal places.

If one of the triangle's angles is 90 degrees, the triangle is said to have right angles. The triangle with a right angle is known as a right triangle because a right angle is 90 degrees. Using the Pythagorean rule, it is simple to understand how the different sides of this triangle relate to one another. The greatest side of a right angle is known as the hypotenuse, and it is opposite the right angle. In addition, the right triangles are categorized as isosceles right triangles and scalene right triangles based on the other angle values. Pythagorean triples are another name for the right triangle's side lengths, which include 3, 4, and 5.

Given that : right triangle, we're provided the hypotenuse and the leg next to. We can use the cosine ratio to determine :

Cosθ =[tex]\frac{adjacent}{hypotenuse}[/tex]

Plug in the given information

Cosθ =[tex]\frac{4}{7}[/tex]

Use the inverse cosine ratio

θ = [tex]cos^{-1} \frac{4}{7}[/tex]

Plug this into your calculator (and ensure you're solving for radians instead of degrees in the settings)

θ =0.9626

Therefore, θ = 1.0 when rounded to one decimal places.

Euclidean geometry is the study of flat and solid figures based on the axioms and theorems of the Greek mathematician Euclid (c. 300 BCE). Euclidean geometry is the plane and solid geometry that is usually taught in High schools.

Euclidean features are ideally suited to defining man-made settings (which are usually in 3D) and are reasonably simple for the user to give.

The incorporation of scene restrictions into the model acquisition process decreases the number of unique configurations for calibration and enables model reconstruction using small sets or even single photos despite the presence of multiple occlusions.

Another obvious use for such a technology is augmented reality. After rebuilding, real-world scene models can be merged with other reconstructed or synthetic models. This is particularly beneficial in architectural applications.

Indeed, before an architectural project is approved, its influence on the existing environment is represented using hand-drawn or computer-aided design (CAD) city models.

The process of creating such models is time-consuming and needs more previous knowledge than scene reconstruction from photos.

Furthermore, when necessary, classic architectural resources such as maps and architectural drawings are simple to include in an interactive reconstruction method.

The values of x that satisfies the inequality are:

x = 0 and x = 3

Given,

The inequality = 7 + 4x > x - 2

We have to find the values of x that satisfies the inequality.

Lets check:

7 + 4 × -3 > -3 - 2

7 - 12 > -5

-5 > -5

Here, -5 = -5

So,

The value x = -3 will not satisfy the inequality

7 + 4 × 0 > 0 - 2

7 > -2

The value x = 0 satisfies the inequality

7 + 4 × 3 > 3 - 2

7 + 12 > 1

19 > 1

The value x = 3 satisfies the inequality

7 + 4 × -6 > -6 - 2

7 - 24 > -8

Answer:

Step-by-step explanation:

See explanation below

Explanation:

From the question, we are told line TV is perpendicular to line US.

This means the point which they intersect has an angle of 90°.

We are also told line TV bisects STU.

For a line to bisect an angle, it means it divided the angle into two equal parts.

When line TV bisects STU, it divided it into angle STR and angle UTR

Hence, ∠STR = ∠UTR

Also line SU and line and line VT intersect to give vertical angles.

Angle R and the angle opposite it are vertical angles.

Vertical angles are equal.

The angle with 90° and the angle opposite it is also a vertical angle.

you can see from the illustration. The two angles opposite each other are equal to 90°.

Since angle on a straight line = 180°

angle R + 90° = 180°

angle R = 180-90

angle R = 90°

All the 4 angles that result from the intersection line VT and line SU are equal to 90°

When you rationalize an equation, you remove any surpluses from the fractions' bottom (denominator). Typically, when you are requested to rationalize or simplify an expression, it also suggests that you should do so.

To make a fraction's denominator a rational number, we rationalize any radicals or surds present. To accomplish this, we often multiply the numerator and denominator by an appropriate radical, then simplify. Divide and multiply the supplied fraction by the same square root value to rationalize the denominator. The denominator will be a rational integer in this case.

Step-by-step explanation:

Based on the interval, the average rate of change of the function is 4.0

The graph that completes the question is added as an attachment

From the graph, we can see  that the equation of the graph is a quadratic equation

Also, from the question:

We have the interval to be:

The interval is given as

x = -4 to x = 2

This can be represented as

(a, b) = (-4, 2)

From the attached graph, we have

f(-4) = 22

f(2) = -2

The estimate of the average rate of change f is calculated as(to one decimal place)

Rate = [f(b) - f(a)]/[b - a]

Substitute the known values in the above equation

This gives

Rate = [f(2) - f(-4)]/[2 + 4]

Substitute the known values in the above equation

So, we have

Rate = [-2 - 22]/[2 + 4]

Evaluate

Rate = -4.0

Hence, the estimate (to one decimal place) of the average rate of change of the graph is 4.0

The length and the width of the sticky note in millimeters are 2.5 × 10⁻⁵ millimeters and 1.25 × 10⁻³ millimeters respectively.

The dimension of Kendra's sticky note using a meter stick are:

The width of the sticky note is 1.25 × 10⁻⁸ meters and the length of the sticky note is 2.5 × 10⁻⁶ meters.

Now we know,

1 meter = 1000 milimeters.

Therefore, the length of the sticky note in millimeters will be:

L = 2.5 × 10⁻⁸ meters

L = 2.5 × 10⁻⁸ × 1000 millimeters

L = 2.5 × 10⁻⁸ × 10³ millimeters

L = 2.5 × 10⁻⁸ ⁺ ³ millimeters

L = 2.5 × 10⁻⁵ millimeters

So, the width of the sticky note is:

W = 1.25 × 10⁻⁶ meters

W = 1.25 × 10⁻⁶ × 10³ millimeters

W = 1.25 × 10⁻³ millimeters

Hence, the dimension in millimeters is: the width and length of the sticky note is 1.25 × 10⁻³ millimeters and 2.5 × 10⁻⁵ millimeters respectively.

When a number is represented as the sum of its prime factors, this process is known as prime factorization. In prime numbers, there are just two factors: one and the number itself. 2, 3, 5, 7, 11, 13, and other prime numbers are examples of prime numbers. A number is prime factorized when it is represented as a collection of primes.
