Amanufacturer of potato chips would like to know whether its bag filling machine works correctly at the 444.0 gram setting. it is believed that the machine is underfilling the bags. a 40 bag sample had a mean of 443.0 grams. a level of significance of 0.02 will be used. is there sufficient evidence to support the claim that the bags are underfilled? assume the standard deviation is known to be 23.0. what is the conclusion?

How can you decide witch operations to use to slice a two step equation

You need to solve a system of equations. you decide to use the elimination method. which of these is not allowed? 3x - 2y = 7 3x + 4y = 17 equation 1 equation 2

The equation shown below represents function f. f(x)= -2x+5 the graph shown below represents function g. which of the following statements is true? a. over the interval [2, 4], the average rate of change of f is the same as the average rate of change of g. the y-intercept of function f is less than the y-intercept of function g. b. over the interval [2, 4], the average rate of change of f is greater than the average rate of change of g. the y-intercept of function f is greater than the y-intercept of function g. c. over the interval [2, 4], the average rate of change of f is the same as the average rate of change of g. the y-intercept of function f is greater than the y-intercept of function g. d. over the interval [2, 4], the average rate of change of f is less than the average rate of change of g. the y-intercept of function f is the same as the y-intercept of function g.
