Answer:

The interval [25, 35] has the slowest average rate of decay.

Step-by-step explanation:

The number of grams in a sample of radium is represented by the function r(t) = 50\cdot e^{-0.013\cdot t}, which is a monotonous decreasing function. Hence, the greater the values of t, the slowest the average rate of decay, represented by a secant line. The interval [25, 35] has the slowest average rate of decay.
