Best ResponseYou've already chosen the best response.0Some doctors use the formula ND=1.08T to relate the variables N (the number of patient appointments the doctor schedules in one day), D (the duration of each patient appointment), and T(the total number of minutes the doctor can use to see patients in one day). Solve the formula for N. Use this result to find the number of patient appointments N a doctor should make if she has 6 hours available for patients and each appointment is 15 minutes long. ( Round your answer to the nearest whole number).

Best ResponseYou've already chosen the best response.0For part B., you need to use T = 6 hours, but you must convert this to minutes. D = 15

Best ResponseYou've already chosen the best response.0whats the second part to this: The number of years a person in the united states is expected to live can be approximated by the equation y=0.189x+70.8,where x is the number of years since 1970.solve this equation for x. use this new equation to determine in which year the approximate life expectancy will be 80.2 years.

Best ResponseYou've already chosen the best response.0this is what i have already y=0.189x+70.8 Subtract 70.80 from both sides y 70.8=0.189x Divide both sides by 0.189x y70.8/0.189=x
