Mary is carrying out a survey of the length (2 cm) of leaves on the plants in her garden. A sample of ten lengths is
13.5.8.9. 14.8. 176.5.8. 13.7. 15.5.8.9. 11.8. 13.5
Mark groups the leaf lengths into intervals
How many of the measurements would be in the interval 13.5 5 2 < 15.5?​

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
