Question

(Select all that apply) which of the following commands will produce a duration variable with a value of exactly 364 days? a. calyears(1)-1 b. calmonths (12)-days (1) c. 52*days (7) d. days (364)

Answer 1

Options c (52*days(7)) and d (days(364)) both accurately produce a duration of exactly 364 days by respectively multiplying the number of weeks in a year by the days in a week and directly specifying the duration.

Step-by-step explanation:

The student's question relates to operations with units of time, specifically on how to produce a duration of exactly 364 days using different time-related functions and multiplication.

The correct commands that would result in a duration of 364 days are:

• c. 52*days(7): Multiplying 52 weeks by 7 days each (since there are 7 days in a week).
• d. days(364): Directly specifying the duration as 364 days.

Both options c and d will yield a duration of exactly 364 days. The other options (a and b) do not accurately represent a year's worth of days minus one.

Answer 2

The commands that produce a duration variable with a value of exactly 364 days are. days(364)' and 'c. 52*days(7)'. The other commands do not result in the exact duration of 364 days.

Step-by-step explanation:

The question involves determining which commands will produce a duration variable with a value of exactly 364 days. The following are the correct commands:

• d. days(364): This directly creates 364 days.
• c. 52*days(7): Multiplying 52 weeks by 7 days also gives us 364 days.

Commands a and b will not result in a duration of 364 days:

a. calyears(1)-1: This subtracts one day from a calendar year, which assumes a year of 365 days, not accounting for leap years, and hence does not give an exact duration of 364 days.

b. calmonths(12)-days(1): This subtracts one day from 12 calendar months, which could vary depending on the actual days in each month, and may not yield exactly 364 days.
