Answer 1

The three TRUE statements are:

1. Date Serial numbers are sequential, starting from 1.
2. The Date Serial number of 1 corresponds to the date 1900-01-01.
3. Date Serial numbers are what powers Date Functions in Excel.

The Date Serial number of 1 corresponds to the date January 1, 1900. Each subsequent day is represented by an integer incrementing from 1. For instance, January 2, 1900 has a Date Serial number of 2, and February 1, 2000 has a Date Serial number of 36526.

So, Date Serial numbers can be used with various functions in Excel, including DATE(), DATEDIF(), and DAY(). They can also be directly entered into cells and displayed as dates. The YEARFRAC() function specifically calculates the fraction of a year represented by a date range.
