Two students each write a function, C(n), that they think can be used to find the number of circles needed to make the nth figure in the pattern shown. Use the drop-down menus to explain why each function does or does not represent the number of circles needed to make the nth figure in the pattern.

We just started the introduction into circles and i have no idea how to do this.

Peter applied to an accounting firm and a consulting firm. he knows that 30% of similarly qualified applicants receive job offers from the accounting firm, while only 20% of similarly qualified applicants receive job offers from the consulting firm. assume that receiving an offer from one firm is independent of receiving an offer from the other. what is the probability that both firms offer peter a job?

Solve 30% of what = 60 step by step
