Can you write out the SQL expression for this and give an explanation?:

Write the code to:

Display the number of hours each instructor has spent teaching the tango and rumba lessons. Show

the instructor's name $($instructor$),$ then the dance name $($dance$),$ then the hours $($hours$\_$taught$)$ only if

the instructor has taught at least $10$ hours but $20$ hours at most $($between$).$

Store the result in tango$\_$rumba$\_$instructor$\_$hours.
