Suppose that a substance is dissolving into a liquid which is at rest in a container. assume further that no mass enters or escapes the container. on the basis of (4-2) with u = 0, give a physical argument showing that lim c(x, t) = co, 14시 where co is a constant. argue that co c(x, 0) dx, where v is the set making up the container and |v is its volume.

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.
