31 is just confusing
32 i get since i can put it on a calculator
and 33 and 34 are just plain hard
if you guys can answer it thank you so much and if not still thank you so much for all your help

sorry im using up all your time asking you guys these questions but your answers are helping me alot
sorry for all the questions but 2 more questions i forgotten to ask
for number 25 would i use area of a triangle? if so would the setup for it be K=1/2(11 x 13) sin(70)? if not how do you do it, if so say yes? thanks
and nuber 26 how would i do that also?
thanks alot for all the help
This is a quadratic eqaution. solve it, then plug in the values for q that you get to see which solutions are extraneous (we often get extraneous, that is, solutions that don't work, when we square both sides of an equation).
Can you take it from here?
at most means less than or equal to, so at most 5 means 5 or less
i don't suppose you have a problem with phrases like "greater than," "less than," or "exactly"
you need to use Bernoulli Trials to do this problem. Now that you know what at least means, can you do it?

Note that this is quadratic in , you can see this explicity if you were to say let then you would get . But don't bother with that, it's usually a waste of time. Just solve this like a regular quadratic and tell me the answers you get for
