# In a study of the effect of diet on cholesterol, rats were fed several different diets. one diet had 5% added fiber from oat bran. the study report gives results in the form "mean plus or minus the standard error of the mean." this form is very common in scientific publications. for the 9 rats fed this diet, blood cholesterol levels (in milligrams per deciliter of blood) were 89.02 ± 5.26. what are x and s for these 9 rats? (use 2 decimal places.)

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
