How is the empirical probability of an event estimated? 1. by repeating a random experiment and counting the number of times the event occurs 2. by using logic and prior experience to determine the liklihood of the event 3. by finding the probability of the complement of the event 4. by using probability theory to model all possible outcomes, including the desired event?

What expression is equivalent to (2x-1)(x-3)?

Is this a polynomial function? i need to know asap

Since opening night, attendance at play a has increased steadily, while attendance at play b first rose and then fell. equations modeling the daily attendance y at each play are shown below, where x is the number of days since opening night. on what day(s) was the attendance the same at both plays? what was the attendance? play a: y = 8x + 191 play b: y = -x^2 + 26x + 126 a. the attendance was never the same at both plays. b. the attendance was the same on day 5. the attendance was 231 at both plays on that day. c. the attendance was the same on day 13. the attendance was 295 at both plays on that day. d. the attendance was the same on days 5 and 13. the attendance at both plays on those days was 231 and 295 respectively.
