Suppose that the average and standard deviation of the shelf life in years for certain kinds of batteries are 14.79 and 2.67, respectively. Calculate an interval that is symmetric around the mean such that it contains approximately 68% of battery shelf lives. Assume that the life has a normal distribution.1) (17.46, 12.12)2) (20.13, 9.45)3) (12.12, 17.46)4) (14.79, 2.67)5) (9.45, 20.13)

Apatient is given 50 mg dose of medicine the medicines effectiveness decreases every hour at a constant rate of 40% what is the exponential decay function that models this scenario how much medicine will be left in the patients system after 2 hours

What properties allow transformation to be used as a problem solving tool

The magnitude, m, of an earthquake is defined to be m=log l/s, where i is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and s is the intensity of a “standard” earthquake, which is barely detectable. what is the magnitude of an earthquake that is 1,000 times more intense than a standard earthquake? use a calculator. round your answer to the nearest tenth.
