WebSample Covariance Formula: Sample Cov (X,Y) = Σ E ( (X-μ)E (Y-ν)) / n-1. In the above covariance equation; X is said to be as a random variable. E (X) = μ is said to be the expected value (the mean) of the random variable X. E (Y) = v is said to be the expected value (the mean) of the random variable Y.

WebTo get the equation of a line from a table, you need to determine the slope of the line by calculating the ratio of the change in y-value to the change in x-value. For example, if two points in the table were (1, 2) and (4, 8), you could see that the y value changed by 6 and the x value changed by 3.

WebThis calculator is built for simple linear regression, where only one predictor variable (X) and one response (Y) are used. Using our calculator is as simple as copying and pasting the … WebSolve for Y when X = 6. Solution: Here we will apply the following case: Y varies as the square of X: y = kx2 Putting the values of x and y in the above equation: 100 = k42 100 = k16 k = 100 16 k = 100 16 k = 25 4 So the constant of proportionality becomes: k = 6.25 Now we have the variation equation as follows: y = kx2 y = 6.25x2 y = 6.25 ∗ 62 WebFirstly, convert the equation into the standard form for the line: 5x + 15y = 7 + 3. 5x + 15y = 10. For the x-intercept. Now, this equation is given to the calculator as input: 5x + 15y = 10. The calculator plugs y = 0 into this equation: 5x + 15 (0) = … dave harman facebook
