The body removes antibacterial drugs at a rate in proportion to the amount present. Your task is to:

  • Express this as a differential equation.
  • Assume the initial dosage is 450 milligrams. 7 hours later, 50 milligrams remain inside the body. Determine the decay constant.
  • Proceed given the facts in the previous statement. How long after the drug was administered would 200 milligrams be found in the body?

You decide to further your research project by hypothesizing that the true proportion of core body temperature increases amidst higher ambient temperature and humidity levels for the population who do not use electric fans is less than those who do use electric fans, setting the level of significance at 5% for the formal hypothesis test. In other words, you extend your sampling to two samples instead of just one. You randomly sample 31 and 39 participants for your first and...

A radioactive material disintegrates at a rate proportional to the amount currently present. If Q(t) is the amount present at time t, then dQ/dt=−rQ where r>0 is the decay rate. If 300 mg of a mystery substance decays to 80.84 mg in 3 weeks, find the time required for the substance to decay to one-half its original amount. Round the answer to 3 decimal places.
