If a denotes some event, what does upper a overbar denote? if p(a)equals0.009, what is the value of p(upper a overbar)? if p(a)equals0.009, is upper a overbar unusual? what does upper a overbar denote? a. event upper a overbar is always unusual. b. event upper a overbar denotes the complement of event a, meaning that upper a overbar consists of all outcomes in which event a does not occur. c. events a and upper a overbar share all outcomes. d. event upper a overbar denotes the complement of event a, meaning that upper a overbar and a share some but not all outcomes.

The rate of decay of a radioactive substance depends upon the amount present initially. the mass y (mg) of the radioactive substance cobalt-60 present in a sample at time t (years) is represented by the exponential equation y=50e −0.1315 t . answer the following questions in complete sentences. 1. how does the exponential equation above compare to the equation for simple interest that is compounded continuously? explain the similarities. 2. what is the initial amount of cobalt-60 in the sample? 2. how much cobalt-60 is left after 8.4 years? show your work. 3. what would be the y-intercept of the graph? what does it represent? 4. after how many years will the amount of cobalt-60 left be 6.25 mg? explain what happens to the cobalt-60 after 50 years? 5. discuss some “real-world” examples and uses of cobalt-60
