Una rosa blanca Cultivo una rosa blanca, en julio como en enero, para el amigo sincero que me da su mano franca. Y para el cruel que me arranca el corazn con que vivo, cardo ni ortiga cultivo: cultivo una rosa blanca. Find the area of the nearest hundredth Complete the square to findthe vertex of this parabola.x^2 - 4x + y + 10 = 0([?], [ ]) How does fuligo septica move? why did the Africa kill the Portuguese priest please urgent please beg Describe the changes that occurred during the evolution of dogs from wolves? Please help me I really need it The amount of time (in minutes per day) spent on social media for a sample of 10 teens has a mean of 186.7 and a sample standard deviation of 19.99. An independent sample of 8 older adults has a mean of 93.5 minutes with a sample standard deviation of 32.01. Assume that the time spent on social media is approximately normally distributed for each group. a) Determine the value of the test statistic to test H subscript 0 colon space mu subscript t e e n end subscript equals mu subscript o l d e r end subscript against H subscript A colon space mu subscript t e e n end subscript not equal to mu subscript o l d e r end subscript. b) Determine the p-value or critical value for this test at alpha equals 0.05. c) What is your conclusion about whether the two age groups spend the same average amount of time on social media describe the route of the long march Create a program that will compute the voltage drop across each resistor in a series circuit consisting of three resistors. The user is to input the value of each resistor and the applied circuit voltage. The mathematical relationships are 1. Rt- R1 R2 + R3 It Vs/Rt Where Rt -Total circuit resistance in ohms R1,R2,R3 Value of each resistor in ohms It - Total circuit current in amps Vs -Applied circuit voltage Vn- Voltage drop across an individual resistor n (n-1, 2 or 3) in volts Rn-R1,R2, or R3 Use the values of 5000 for R1, 3000 for R2,2000 for R3, and 12 for Vs. The output of the program should be an appropriate title which identifies the program and include your name. All values should be accompanied by appropriate messages identifying each. Submit a printout of your program and the printed output to your instructor Based on what you've learned about the main elements, themes, and conventions inGothic literature and based on the popular Gothic works that you've read and analyzed,what does the Gothic genre mean to you? If you had to write a Gothic story, what arethe elements and themes you'd want to include and why?Further your participation in the discussion by reading and responding to what otherspost Whats the answer? Down below is a image of the question A 100.0g sample of nickel is heated to 100.0 oC (Celsius) and is placed in a coffee cup calorimeter containing 150. g of water at 25.0 oC. After the metal cools, the final temperature of the metal and the water is 29.8 oC. Calculate the specific heat capacity of nickel from these experimental data, assuming that no heat escapes to the surroundings or is transferred to the calorimeter. Specific heat of water whay is the central idea of the "fact" respone
