boxes of car parts are stacked on top of each other on a work bench. the table shows how the height above the floor of the topmost box depends on the number of boxes. What is the rule for the height? Give the rule in words and as an algebraic expression.

What is x and y (use substitution? ) 5x+3y=38 and y=3x+8?

How can you find the conditional probability of a given b as the fraction of b’s outcomes that also belong to a, and interpret the answer in terms of the model? i just need a good explanation

Determine the number of outcomes in the event. decide whether the event is a simple event or not. upper a computer is used to select randomly a number between 1 and 9 comma inclusive. event upper b is selecting a number greater than 4. event upper b has nothing outcome(s). is the event a simple event? (yes or no) because event upper b has (fewer than, exactly, more than) one outcome.
