The arrival time of my usual morning bus (b) is normally distributed, with a mean eta at 8: 00 am, and a standard deviation of 4 minutes. my arrival time (a) at the bus stop is also normally distributed, with a mean eta at 7: 50 am, and a standard deviation of 3 minutes. (a) with what probability can i expect to catch the bus? (hint: what is the distribution of the random variable x = a – b, and what must be true about x in the event that i catch the bus? ) (b) on average, how much earlier should i arrive, if i expect to catch the bus with 99% probability?

Use the distributive law to multiply. 3(4x + 5y + 6)

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.
