Consider an employee database with two relations employee (employee name, street, city) works (employee name, company name, salary) where the primary keys are underlined. write a function avg salary that takes a company name as an argument and finds the average salary of employees at that company. then, write an sql statement, using that function, to find companies whose employees earn a higher salary, on average, than the average salary at "first bank".

i think ninja is the best

given the lack of choices, i'm gonna wing it and say that pushing your car off a cliff might not be the best idea. your car might sustain damage from the fall and will probably result in the car being too damaged to jump start.

if that's not good enough, avoid filling the car with bees. bees might get agitated when trapped or during the moving process, and might result in death or painful stings that will make jump starting your car very difficult. but in the event that you do choose to fill your car with bees, remember to wear protective gear!

in #3, the vertical forces are not balanced; the object is accelerating downward.

in #4, neither the vertical nor the horizontal forces are balanced. the object is accelerating upwards and to the right.
