The answer must be given as a fraction, NO DECIMALS. If the answer involves a square root it should be entered as sqrt . For instance, the square root of 2 should be entered as sqrt(2). If cosθ=−2/7 and tanθ<0, then sin(θ)= tan(θ)= cot(θ)= sec(θ)= csc(θ)=

For the following sequence determine the common difference (if it is an arithmetic sequence) or the common ratio (if it is a geometric sequence).

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.
