Accepted Solution

A:
Answer: The initial number of transactions is neither an independent nor a dependent variable.Step-by-step explanation:Here, The initial number of transactions that took place in the first hour of day is 10 and the number of transactions doubles every hour after that.If x represents the number of hours and y represents Number of transaction after x hours.Therefore, The function which represents the situation is,[tex]y = 10\times 2^x[/tex]Where x is independent variable, while y is dependent variable.Since initially x=0,   y=10 which is the initial transaction.And, there is not any impact on the value of 10 by changing the values of x or y, Also 10 is not a variable( because it is a constant value)Therefore neither it is dependent variable nor it is independent.
