In this problem, y = c₁eˣ + c₂e⁻ˣ is a two-parameter family of solutions of the second-order de y'' − y = 0. find a solution of the second-order iv p consisting of this differential equation and the given initial conditions. y(-1) = 4, y'(-1) = -4.

What does the relationship between the mean and median reveal about the shape of the data

The american academy of pediatrics wants to conduct a survey of recently graduated family practitioners to assess why they did not choose pediatrics for their specialization. provide a definition of the population, suggest a sampling frame, and indicate the appropriate sampling unit.

Select the margin of error that corresponds to the sample mean that corresponds to each population: a population mean of 360, a standard deviation of 4, and a margin of error of 2.5%
