Algebra Question for Electrical Engineers Solve for x. 1= x+ (3 * 10-13 ) * Here, x represents the Voltage across Diode. The answer should be in ln(something..). It looks simply but hope you can help me. I really need a step by step explanation. Please do not use Matlab!! The answer I got from Matlab was 0.718. e 26 10-3
I really do need help please 7. X, Y have joint density f(x,y) = 2 if 0 < r <y< 1, S(x, y) = 0 otherwise. Compute the conditional density fxiy
Below is a small data set showing observations on two variables X and Y. X Y 0.408 0.173 0.275 0.084 0.375 0.115 0.349 0.156 0.312 0.070 0.382 0.210 We are especially interested in determining if there is a linear relationship between Y and X (Y is the dependent variable and X is the explanatory variable). a) Begin by making a scatterplot of Y vs X. b) Estimate a linear equation for predicting Y given X. c) How good is your...
Please answer the A,b, and C in clear handwriting. Consider the following cases involving sinusoids: (a) 3.3 Find the Laplace transform of r(t) = sin(2n)[u(I)-a(1-1)I and its region of convergence. Carefully plot yt). Determine the region of convergence of Y(s) (b) A very smooth pulse, called the raised cosine, is x(t) = 1-cos( 2π 1), O 1 1, and zero elsewhere. Find its Laplace transform and its corresponding region of convergence. (c) Indicate three possible approaches to finding the Laplace...
Given Var(X) = 4, Var(Y) = 1, and Var(X+2Y) = 10, What is Var(2X-Y-3)? I know the answer is 15, I'm particularly interested in the specific steps involved with finding the cov(X,Y) in this problem. Please explain in detail, step by step how you come to cov(X,Y) = 0.5 in this equation. Please include any formulas you would need to use to find the cov(X,Y) in this equation.
3. X = b(200, p), p0 = 0.6, x = 155, the significance level is α = 0.01. The null hypothesis is p = p0, the alternative hypothesis is p > p0. Should we accepts or reject the alternative hypothesis look below: I know the answers to this problem. I just need help on finding the critical value z. PLEASE EXPLAIN
The estimated regression equation for a model involving two independent variables and 10 observations follows. y^= 30.6764 + .8162x1 + .4221x2 a. Interpret b1 and b2 in this estimated regression equation. b1 = [- Select your answer -(y changes by 0.8162 when x1 increases by 1 unit and x2 stays the same) (y changes by 0.8162 when x2 increases by 1 unit and x1 stays the same) (y changes by 0.4221 when x1 increases by 1 unit and x2 stays...
