A data analyst runs the following command:SELECT age, countryFROM my_tableWHERE age >= 75 AND country = 'canada';Which of the following tables represents the output of the above command?A)B)C)D)E)
I practiced a similar question last week, and I think the output should only show people from Canada who are 75 or older. I’ll go with option A, but I’m not completely confident.
This reminds me of a practice question where we had to identify outputs based on specific conditions. I think it might be option C, but I could be wrong.
I'm a little confused by the different table formats in the options. I'll need to carefully analyze each one to determine which one matches the SQL query.
Okay, let's think this through step-by-step. The query selects the age and country columns from the my_table table, where the age is greater than or equal to 75 and the country is 'canada'. I'll compare the options to that.
Probability tree diagram seems like the most straightforward way to visualize the different task durations and their likelihoods. I'll start by mapping that out and see where it leads.
