Ineed or else im in trouble need a random sample of 240 park users were asked if they go to the park more often on weekdays or on the weekend. the results are shown in the table. weekdays weekend male (50) (10) female (150) (30) based on the data in the table, select correct or incorrect for each statement. correct or incorrect 1.the males go to the park more often on the weekend. 2.the females go to the park more often on weekdays. 3.for the participants in the survey, gender affects which days of the week a person goes to the park.

At a book fair, joe bought 24 books at 3 for $5 and had $2 left. how much money did he have at first?

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.
