In recent years, a town experienced an arrest rate of 25% for robberies. the new sheriff compiles records showing that among 30 recent robberies, the arrest rate is 30%; he claims that this arrest rate is greater than the 25% arrest rate in the past. using a 0.05 significance level to test the claim, find the p-value. a. 0.7357 b. 0.2643 c. 0.6300 d. 0.5286

Arrange the steps to solve this system of linear equations in the correct sequence. x + y = -2 2x – 3y = -9 tiles subtract 3x + 3y = -6 (obtained in step 1) from 2x – 3y = -9 (given) to solve for x. substitute the value of x in the first equation (x + y = -2) to get y = 1. the solution for the system of equations is (-3, 1). x = -15 the solution for the system of equations is (-15, 13). add 3x + 3y = -6 (obtained in step 1) to 2x – 3y = -9 (given), and solve for x. x = -3 substitute the value of x in the first equation (x + y = -2) to get y = 13. multiply the first equation by 3: 3(x + y) = 3(-2) 3x + 3y = -6.
