Consider the lawsch85 dataset from the wooldridge package in R. Using OLS, estimate the equation: og(saary)=β0+β1LSAT+β2GPA+u log(salary) = \beta_0 + \beta_1 LSAT + \beta_2 GPA + u Suppose the median LSAT score for the students of a law school is 158 and their median college GPA is 3.5. What is the expected average salary for graduates of this law school? Hint: Note that the question is asking for average salary, not the average of og(saary)log(salary). Round your answer to two decimal places

Four airplanes carrying a total of 400 passengersarrive at the detroit airport. the airplanes carry, respectively,50, 80, 110, and 160 passengers.a) one of the 400 passengers is selected uniformly at random.let x denote the number of passengers that were on theairplane carrying the randomly selected passenger. find var(x)for x as given in the problemb) one of the 4 airplane drivers is also selected uniformly atrandom. let y denote the number of passengers on the chosen driver’s airplane. find var(y) for y as given in the problem

Astudent draws two parabolas on graph paper. both parabolas cross the x-axis at (-4, 0) and (6,0). the y-intercept of thefirst parabola is (0, –12). the y-intercept of the second parabola is (0-24). what is the positive difference between the avalues for the two functions that describe the parabolas? write your answer as a decimal rounded to the nearest tenth.
