Melanie and three of her classmates worked as a team to find the experimental probability of a spinner landing on a blue section. Melanie performed 10 trials.
Enrique performed 50 trials.
Veronique performed 300 trials.
Juanita performed 500 trials.

Compare the four experiments. Which student is most likely to get an experimental probability best suited for predicting frequencies?
Melanie
Enrique
Veronique
Juanita

1. are the triangles similar and if so why? what is the value of x? show your work.

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
