Mr yosgi has 75 papers he graded 60 of them and let a student grade the rest what percent if the papers did each person grade?

The mean of a set of data is -3.82 and its standard deviation is 2.31. find the z score for a value of 3.99.

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

Icould really use some with this question.
