EOCT Review a)It would remain the same. b)It would increase by 3. c)It would decrease by 3. a Janet and Ed had the following scores: Janet's scores: 50, 90, 70, 75, 80, 80, 90, 85, 90, 90 Ed's scores: 75, 75, 80, 90, 95, 80, 80, 75, 75, 75 If three points were added to Ed's scores what would happen to the mean deviation?

EOCT Review a)1/16 b)1/8 c)3/16 d)3/8 c Given a spinner with 8 equal sections numbered 1 through 8, what is the probability that you would spin an even number in the first spin and a number less than 4 in the second spin?

EOCT Review a)It would remain the same. b)It would increase by 2. c)It would increase by 1.1. b Janet and Ed had the following scores: Janet's scores: 50, 90, 70, 75, 80, 80, 90, 85, 90, 90 Ed's scores: 75, 75, 80, 90, 95, 80, 80, 75, 75, 75 If each of Ed's scores were multiplied by 1.1 what would happen to the range?

3.11-Rational Equations 2 methods 1.Simplify and Cross-multiply. 2.Multiply by the LCD.

Cross multiplying is appropriate for solving equations in which each side is a single rational expression. x = 10

SOLVE these Examples (dont forget to check answers) x=1m=5

SOLVE these Examples y=3, -10

A second method, multiplying by the LCD, works for any rational equation. Just multiply the TOP ONLY by the LCD. x=3

SOLVE these Examples x=4

SOLVE these Examples x = -2

SOLVE these Examples x = 4
