Cramer’s Rule is a method in linear algebra used to solve a system of linear equations with the same number of equations as unknowns, provided the system has a unique solution. It works by expressing each variable as a ratio of determinants. For a system AX = b, where A is a square coefficient matrix and b is the constant vector, the solution for the i-th variable is given by det(A_i) / det(A). Here, det(A) is the determinant of the coefficient matrix, and det(A_i) is the determinant of the matrix obtained by replacing the i-th column of A with the constant vector b. Cramer’s Rule is elegant and straightforward, but it is practical only for small systems, since computing determinants of large matrices can be computationally expensive. #math #learning #linearalgebra #cramersrule #reels

✨️Code link in bio✨️In probability theory and statistics, a normal distribution or Gaussian distribution is a type of continuous probability distribution for a real-valued random variable. The general form of its probability density function is f(x) = 1/√(2πσ²) e^(-(x-μ)²/(2σ²)) 📐 The parameter μ (mu) is the mean or expectation of the distribution (and also its median and mode), while the parameter σ² is the variance. The standard deviation of the distribution is σ (sigma). A random variable with a Gaussian distribution is said to be normally distributed, and is called a normal deviate. 📊 Normal distributions are important in statistics and are often used in the natural and social sciences to represent real-valued random variables whose distributions are not known. Their importance is partly due to the central limit theorem. It states that, under some conditions, the average of many samples (observations) of a random variable with finite mean and variance is itself a random variable—whose distribution converges to a normal distribution as the number of samples increases. Therefore, physical quantities that are expected to be the sum of many independent processes, such as measurement errors, often have distributions that are nearly normal. ⚡ Moreover, Gaussian distributions have some unique properties that are valuable in analytic studies. For instance, any linear combination of a fixed collection of independent normal deviates is a normal deviate. Many results and methods, such as propagation of uncertainty and least squares parameter fitting, can be derived analytically in explicit form when the relevant variables are normally distributed. 🎯 A normal distribution is sometimes informally called a bell curve in data science and machine learning. However, many other distributions are bell-shaped (such as the Cauchy, Student's t, and logistic distributions). This demonstration shows the fundamental principles of probability theory that underpin artificial intelligence and statistical modeling. 🌟 #math #mathematics #fyp

Linear regression is a statistical method used to model the relationship between a dependent variable and one or more independent variables. In its simplest form, simple linear regression examines how a single predictor variable relates to an outcome by fitting a straight line through the data. The line is chosen so that the sum of the squared differences, known as residuals, between the observed data points and the predicted values is minimized. This process, called the least squares method, produces an equation of the form y = mx + b, where m represents the slope, showing how much the dependent variable changes for a unit change in the independent variable, and b is the intercept, indicating the starting value when the predictor is zero. Linear regression is not only useful for understanding relationships but also for making predictions. By analyzing the slope and intercept, one can determine both the strength and direction of the association between variables. For example, it might be used to predict housing prices based on square footage, or to forecast sales from advertising budgets. Multiple linear regression extends this idea by incorporating several independent variables, allowing for more accurate modeling of complex systems. Despite its simplicity, linear regression remains one of the most widely used and important tools in statistics and data science.

How we did it 👀👇 The question gives us x^4/3 and tells us that x must be a value greater than 0. We can set x equal to any value above 0, in this context we used 2. By setting x equal to 2 as a specific variable (x1), we can solve the equation given in the question, and now know that x^4/3 = 2.5198. Now, we can simply type in the answer choices verbatim and replacing x with x1 and see which ones are equivalent to 2.5198. Since I and II match the given equation in the problem, the answer is C, I and II.

Visualisation to the derivative function. In mathematics, the derivative is a fundamental tool that quantifies the sensitivity to change of a function's output with respect to its input. The derivative of a function of a single variable at a chosen input value, when it exists, is the slope of the tangent line to the graph of the function at that point. The tangent line is the best linear approximation of the function near that input value. For this reason, the derivative is often described as the instantaneous rate of change, the ratio of the instantaneous change in the dependent variable to that of the independent variable.
