The principle uses a computer to randomly select the name of a student from all the students in the school. With the computer program, it is possible to draw the name of the same student twice. If the principle selects the name of a student from the Blazers on the first try, what is the probability she will draw the name of a student from the Blazers on the second try?

1) 1/5
2) 1/8
3) 79/399
4) 1/80

What is an equation for the translation (x - 2)^2 + (y + 1)^2 = 16 by 4 units left and 6 units up?

1) (x + 2)^2 + (y - 5)^2 = 16
2) (x - 2)^2 + (y - 5)^2 = 16
3) (x + 5)^2 + (y - 2)^2 = 16
4) (x + 4)^2 + (y - 5)^2 = 16

  1. #1 - the probability is the same on every draw, since no names are removed when drawing: 80/400

    and that's "principal."

    #2
    (x-2+4)^2 + (y+1-6)^2 = 16

  2. so in other words 1/5, because 80/400=1/5
    I know I'm extremely late, but like... :)
