The probability that a student chosen at random dislikes at least one of them is 0.2. Probability is the likelihood of occurrence of an event.
Probability a student likes math's = 0.7
Probability a student dislikes maths = 1 - 0.7 = 0.3
Probability a student likes history = 0.2
Probability a student dislikes history = 1 - 0.2= 0.8
Probability a student likes maths and history = 0.1

what is an angle?Euclidean geometry defines an angle as a shape made up of two rays, referred to as the angle's extremities, that come together at a vertex in the middle. Two rays may combine to form an angle in the surfaces where they are positioned. When two planes collide, an angle too is created. They are referred to as dihedral angles. The shape that two rays and lines with a similar termination can adopt in plane geometry is called an angle. The word "angle" in English is derived from the Latin word "angulus," which meaning "horn."
Here,
Given :
=> m∠1 + m∠5 = 180°
=> m∠1 + m∠4 = 180°
To prove :
YZ || UV
Since,
=> m∠1 + m∠5 = m∠1 + m∠4

Do you know the answer?
To convert an area from inches to centimeters, conversion factor should be 15.24 square centimeters.
To convert an area from inches to centimeters, we use the conversion factor of 2.54 cm per inch.
This means that for every inch, there are 2.54 centimeters. In order to find the area in centimeters, we first need to find the area in inches, and then multiply it by 2.54.
To find the area, we use the formula
=> area = length x width.
Let's say the length of a rectangle is 2 inches and the width is 3 inches. The area of this rectangle would be 6 square inches
=> (2 x 3 = 6).
To convert this area to square centimeters, we multiply the area in inches by 2.54.
So,
=> 6 square inches x 2.54 = 15.24 square centimeters.

Como se puede ver, el gasto del canal calculado con el método de integración gráfica coincide con el caudal transportado, por lo que el cálculo es correcto.
El caudal transportado es el volumen (m3) de agua que fluye a través de una sección transversal de un canal por unidad de tiempo, en este caso es de 18.4m3/s. La pendiente de fondo es la pendiente de la superficie de fondo de un canal, en este caso es de 0.022. El coeficiente de rugosidad es una medida de la rugosidad del canal, en este caso es de 0.024.
Para calcular el gasto del canal utilizando el método de integración gráfica, se usa la siguiente fórmula:

Time complexity
The time complexity is the number of operations an algorithm performs to complete its task . The algorithm that performs the task in the smallest number of operations is considered the most efficient one in terms of the time complexity.
The number of operations in the best case is constant. The best-case time complexity would therefore be Θ (1). Most of the time, we perform worst-case analysis to analyze algorithms. In the worst analysis, we guarantee an upper bound on the execution time of an algorithm which is good information.

Differentiation from First Principles is a formal method for determining a tangent's gradient.
What is meant by differentiation?
Finding a function's derivative is the process of differentiation. It is also the process of determining how quickly a function changes in relation to its variables.
According to the Sum rule, a sum of functions' derivatives equals the sum of those functions' derivatives. The derivative of two different functions is the difference of their derivatives, according to the Difference rule.
Differentiation from First Principles is a formal method for determining a tangent's gradient. The straight line connecting any two locations on the curve that are fairly near to one another will have a gradient that is similar to that of the tangent at those places.
s(t) = ∫vdt = ∫sin(πt)dt = (-cos(πt))/π + c
substituting the values t = 3, we get
s(-3) = (-cos(-3π))/π + c = 0
simplifying the above equation, we get
(-cos(3π))/π + c = 0
1/π + c = c
c = -1/π
Therefore, the correct answer is s(t) = (-cos(πt))/π - 1/π = (-cos(πt) - 1)/π.

suppose one draws two balls (without replacing the first ball) from a bag containing 3 red balls and 2 blue balls. what is the probability that the first ball is red and the second one is blue?
The probability that the first ball is red and the second one is blue is 0.3.
This is calculated by first finding the probability of drawing a red ball, which is 3/5, and then the probability of drawing a blue ball after a red ball has been removed, which is exactly evaluated as 1/4. To find the combined the probability, we multiply the two probabilities: 0.3 = (3/5) * (1/4). This means that if we perform this experiment many times, on average, we would expect to draw a red ball first followed by a blue ball in 30% of the trials.

The correct method of labelling the population for SRS is 001 - 690.
What is a simple random sample(SRS)?
In statistics, a simple random sample is a subset of people chosen at random from a larger group, all of whom were chosen with the same probability. It is a method of choosing a sample at random.
For the given question,
Total number of students = 690
Number of students to be selected for SRS = 50
One method of creating a straightforward random sample is to number the students from 1 to 690 before using a random number generator to select 50 numbers. A random sample is the most effective at eliminating potential bias because every member of the population has an equal chance of being chosen.
Any two participants must have an equal chance of being selected for the sample, and any group, that isn't larger than the sample size, must be able to have all of its members selected.
Therefore the correct method of labelling the population for SRS is 001 - 690.

What is the tilde approximation of the following growth function? f(n) = n + 5n^4 + nlg(n) ~n^4does not exist ~5 5n^4 ~5n^4 n^4~nlg(n)
The tilde approximation of the growth function f(n) = n + 5n^4 + nlg(n) is ~5n^4.
The tilde notation is used to describe the asymptotic behavior of a function, which means how the function grows relative to other functions as the input gets very large.
To determine the tilde approximation of the function f(n) = n + 5n^4 + nlg(n), we need to identify the term that grows the fastest as n becomes very large.
Analyze the first term: n. As n gets larger, the term n becomes relatively smaller compared to the other terms in the function.
Analyze the second term: 5n^4. This term grows much faster than the first term as n becomes larger.
Analyze the third term: nlg(n). The logarithmic term grows slower than the polynomial term, meaning that it becomes relatively smaller as n becomes larger.
Based on the analysis above, we can conclude that the dominant term in the function is 5n^4.
Therefore, the tilde approximation of the function f(n) = n + 5n^4 + nlg(n) is ~5n^4, meaning that the function grows approximately as n^4 when n becomes very large.
