(System of equations) A drama club sells a total of 196 tickets for a production. An adult ticket costs $8 and
a student ticket costs $4, and the club earned a total of $1,040 from ticket sales. How many
adult (x) and student (y) tickets were sold? Write a system of linear equations to
represent this situation. Use substitution to solve the system of equations.

17. a researcher measures three variables, x, y, and z for each individual in a sample of n = 20. the pearson correlations for this sample are rxy = 0.6, rxz = 0.4, and ryz = 0.7. a. find the partial correlation between x and y, holding z constant. b. find the partial correlation between x and z, holding y constant. (hint: simply switch the labels for the variables y and z to correspond with the labels in the equation.) gravetter, frederick j. statistics for the behavioral sciences (p. 526). cengage learning. kindle edition.
