The lifespans of meerkats in a particular zoo are normally distributed. The average meerkat lives 10.4 years, the standard deviation is 1.9 years,
Use the empirical rule (68 - 95 - 99.7%) to estimate the probability of a meerkat living less than 16.1
years.

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
