Negation means negative of something , in logical mathematics negation is an expression opposite to another operation .
Examples of negation are ,
The negation of P is ∼P.The negation of A ^ B^ C is ∼( A ^ B ^ C ).The negation of A is ∼( A ).The negation of Y ^ VB is ∼( Y ^ VB ).The negation of 6 ^ 7is ∼( 6 ^ 7).Logical operations are performed to check the trueness of an expression.
These are generally Boolean expressions or algebraic functions.
A negation of a basic assertion is made by inserting the word "not" into the original statement. The truth value of the negation will always be the inverse of the truth value of the original assertion.
Under negation, what was true becomes false and the vice - versa.

Rudy says that the sum of the measures of the exterior angles of a regular hexagon is 720°. Is Rudy correct? Why or why not?
Answer:
Yes, Rudy is correct
Explanation:
Number of sides of a hexagon = 6
The sum of all interior angles of a polygon with n sides = (n-2)*180
Here, since a regular hexagon has 6 sides, n = 6
= (6 - 2)*180
= 4*180
= 720 degrees

What is Projective tests?Projective tests are created so that the test taker cannot tell what they are testing for.A personality test used in psychology is called a projective test. This kind of test provides answers to confusing situations, phrases, or visuals. Unconscious motivations or attitudes are disclosed by asking the person a question or giving them a stimulus that is unclear. Projective exams are designed to enlighten individuals about sentiments, wants, and conflicts that are not readily apparent to them. Psychoanalysts try to find unconscious feelings that might be behind a person's troubles in life by evaluating responses to ambiguous stimuli. Projective testing is mostly used to evaluate personality functioning.To learn more about Projective tests refer to:

Type the correct answer in each box. Use numerals instead of words. Find the missing side and angle measures in triangle ABC. Round your answers to the nearest tenth. Scalene triangle ABC with side AC labeled 23 and side BC labeled 15. Angle A measures 40 degrees. The measure of angle B is approximately . The measure of angle C is approximately . The length of side AB is approximately
The measures of the angles of the triangles are
The measure of ∠B = 80.3°
The measure of ∠C = 59.7°
The length of side AB = 20.2 units
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the triangle be represented as ΔABC
Now , the measure of side AC = 23
The measure of side BC = 15
The measure of ∠A = 40°
From the law of sines , we get
( sin A ) / a = ( sin B ) / b = ( sin C ) / c
Substitute the value of A and a in the equation , we get
sin ( 40 )° / 15 = sin B / 23
On simplifying the equation , we get
sin B = ( 23/15 ) x sin ( 40 )°
Now , m∠B = 80.27°
So , the measure of angle ∠B = 80.3°
And ,
The interior angles of a triangle is 180°
So , The measure of angle ∠C = 180° - ( 80.3° + 40° )
On simplifying the equation , we get
The measure of angle ∠C = 59.7°
Now ,
From the law of cosines , c² = a² + b² - 2ab ( cos C )
Substitute the value of a , b and cos C in the equation , we get
c² = 15² + 23² - 2 ( 15 ) ( 23 ) cos ( 59.7 )°
On simplifying the equation , we get
c² = 225 + 529 - 348.12363
c² = 405.87
Taking square roots on both sides of the equation , we get
c = 20.156
c = 20.2 units
Therefore, the measure of side AB = 20.2 units
Hence , the measures angles of triangle is solved

How do you describe a logarithmic function?
A logarithmic function is a type of inverse function.
A logarithmic function is a type of inverse function that is commonly used in mathematics and science. It is typically written in the form of y = log base b (x), where b is the base of the logarithm, and x is the input value. The most common bases for logarithms are 10 (common logarithm) and e (natural logarithm).
The logarithmic function is the inverse of the exponential function with base b. This means that if y = log base b (x) then x = b^y
One way to describe a logarithmic function is to say that it represents the exponent to which the base number must be raised in order to produce the input value x. For example, log base 10 of 100 is 2, because 10^2 = 100.
Another way to describe a logarithmic function is to say that it is a way of expressing very large or small numbers in a more manageable form. For example, instead of expressing a number like 10^9 as 1 billion, it can be expressed as 9 using a logarithm to base 10.
It is also important to note that logarithmic function have some key characteristics such as:
The domain of a logarithmic function is x>0, since the logarithm of a non-positive number is undefined.
The range of a logarithmic function is all real numbers.
The graph of a logarithmic function has a vertical asymptote at x=0, since the logarithm of a non-positive number is undefined.
A logarithmic function is increasing over its domain and concave down.
The x-intercept of the graph is (1,0), since the logarithm of 1 is always 0.
Overall, logarithmic functions are mathematical tools that allow us to simplify the representation and manipulation of very large and small numbers, and are used in many areas of science and engineering.

Using the empirical rule, for normal distribution is 68 % of his commutes will be between 23.5 and 32.5 minutes
What is normal distribution?The normal distribution is a probability distribution used to calculate probability for continuous variables.
Here, we have,
to find what percentage of his commutes will be between 23.5 and 32.5 minutes using the empirical rule:
Now, since gabriel commutes to work, the amount of time it takes him to arrive is normally distributed with a mean of 28 minutes and a standard deviation of 4.5 minutes, we need to find the percentage of his commutes will be between 23.5 and 32.5 minutes using the empirical rule.
First, we need to find how many standard deviations away from the mean each value is using the z-score
Z = (x - μ)/σ where
x = value,
μ = mean and
σ = standard devation
For x = 23.5, we have
Z = (x - μ)/σ
Z = (23.5 - 28)/4.5
Z = -4.5/4.5
Z = -1
Z = -1σ
Also, for x = 32.5, we have
Z = (x - μ)/σ
Z = (32.5 - 28)/4.5
Z = 4.5/4.5
Z = 1
Z = 1σ
So, we have that -1σ ≤ (x - μ) ≤ 1σ
So, the values between 23.5 and 32.5 minutes lie within one standard deviation.
Using the empirical rule, this is 68 % of the values.
So, 68 % of his commutes will be between 23.5 and 32.5 minutes

Jackson used all the butter to make the brownies. If each brownie is 19 1 9 of a batch, how many brownies did he make? Enter your answer in the box.
Answer:
9 brownies
Step-by-step explanation:
Since we are not given the total number of batches. Let us assume the total batches is 81
If each brownie is 1/9 of a batch, number of brownie made will be equivalent to:
Amount of brownie made = 1/9 × 81
Amount of brownie made = 81/9 = 9 brownies
Hence he made 9 brownies

A car on a Ferris wheel with a radius of 20 feet. To the nearest foot, how far does the car travel over an angle of pi/3 radians? (Include the unit of measure in your response.)
Answer:21
Step-by-step explanation:
The car on a Ferris wheel with a radius of 20 feet. travels a distance of 125.6 feet
In order to determine the distance that the car has travelled, we will use the formula for calculating the circumference of a circle expressed as:
C = 2πr
r is the radius of the fairy wheel
Given the following parameters
radius = 20 feet
Substitute into the formula of the circumference:
[tex]C = 2(3.14)(20)\\C = 40(3.14)\\C = 125.6 feet[/tex]
This shows that the car on a Ferris wheel with a radius of 20 feet. travels a distance of 125.6 feet
