2. Module #2 Worksheet #1 1. C: The sample space is made up of 8 + 7 + 6 + 5 = 26 balls. The probability of pulling each individual ball is 1. 26 of pulling a yellow ball is 7. 26 2. B: For the first card drawn, the probability of a King is 4. NAME: ___KEY___________________ Since there are 7 yellow balls, the probability Since this card isn't 52 replaced, if a King is drawn first, the probability of a King being drawn second is 3. 51 The probability of a King being drawn in both the first and second draw is the product of the two individual probabilities: 4 3 12 1. 221   x 52 51 2,652 3. A: If each man gains 10 pounds, every original data point will increase by 10 pounds. Therefore, the man with the original median will still have the median value, but the value will increase by 10. The smallest value and largest value will also increase by 10 and, therefore, the difference between the two won't change. The range does not change in value and, thus, remains the same. 4. C: Because the triangles are similar, the lengths of the corresponding sides are proportional. Therefore: 30 30 14 y 14(30 ) 22 30 17.1 x x x     . The proportion also results in the equation 14( 15) 22 26.3 y y y     . 5. D: SOH-CAH-TOA is used to find the missing side length. Because the angle x    22 15 x y   . This results in the equation 0 and adjacent side are known, Making sure to evaluate with an tan60 . 13    0 argument in degrees, this equation gives: 13tan60 13(1.73) 22.49. x 2
