Question 292171: What would be the linear algebraic equation with clearly defined variables to represent the cost of each option?
My scenario is comparing the cost options of a yearly pass to a theme park which is $65.00, to daily visits, which cost $15.00 daily. The park will be visited 12 times during the year.

Question 294112: Hello sorry to bother you but am having a lot of trouble with this linear equation I was told to equal the y to zero then solve and then the x to zero then solve, The fist time I did y and got 5 for y, I had put the x as zero which eliminated the 3/4x and then just left my five? Well now this solving for x for this one is really confusing me, think I'm doing it completely wrong! I appreciate the help, thanks so much!!! Jenny the equation is
y=3/4 x + 5 Thanks for your help!!

Question 294113: I am stuck on this. I don't even understand what it is asking! Can someone break this down for me? Thanks!
Suppose you have some distribution of measurements, and you ALREADY KNOW that exactly 80% of the measurements happen to fall within 2 standard deviations of the mean. Use Chebyshev's Theorem to find the minimum percentage of measurements that are guaranteed to fall between 2 and 3 standard deviations from the mean (i.e. at least as far as 2 standard deviations away from the mean, but at most as far as 3 standard deviations away from the mean).
