An internet service provider wants to gain insight into how its customers use its service. a random sample of n = 1,000 customers is drawn and surveyed. the survey results provide information on basic demographics (e. g., gender, age, ethnicity, education level, etc.) and answers to specific questions about internet use and behavior. which of the following statements are true? (select all that apply.) a. this is an observational analysis because customers were not randomized to the demographic groups with which they belong. b. this is an observational analysis because customers were randomized to the demographic groups with which they belong. c. this is an experiment because customers were randomized to the demographic groups with which they belong. d. this is an experiment because customers were not randomized to the demographic groups with which they belong e. this is an observational analysis because experimental control was in place while the customer's behavior was recorded f. this is an observational analysis because experimental control was not in place while the customer's behavior was recorded g. this is an experiment because experimental control was not in place while the customer's behavior was recorded h. this is an experiment because experimental control was in place while the customer's behavior was recorded

The revenue generated by a bakery over x months, in thousands of dollars, is given by the function f(x) = 2(1.2)* the cost of running the bakery forx months, in thousands of dollars, is given by the function g(x) = 2x + 1.4determine the equation for h if h(x) = f(x) - g(x).oa. m(x) = (1-2)*-x-07b.(x) = 2(1 2 - 2x -0.7)h(x) = -2((1.2) + x + 0.7)d. h(x) = 2((12) - x-0.7)
