Use numerical differentiation to approximate dy/dx at x = 0.2 and x = 0.3 using the central difference formula

It is safe to change data in a query since you are only changing a temporary copy of the data, not the underlying data in the table

Indicate whether the statement is true or false

Create a data set that contains only the following asymmetric binary at- tributes: (Weather = Bad, Driver’s condition = Alcohol-impaired, Traffic violation = Yes, Seat Belt = No, Crash Severity = Major). For Traffic violation, only None has a value of 0. The rest of the attribute values are assigned to 1. Assuming that support threshold is 30%, how many candidate and frequent itemsets will be generated?
