Question 20 (Multiple Choice Worth 5 points) (06.04 MC) The figure below shows a shaded rectangular region inside a large rectangle: A rectangle of length 10 units and width 5 units is shown. Inside this rectangle is another rectangle of length 6 units and width 3 units placed symmetrically inside the larger rectangle. The smaller rectangle is shaded gray. What is the probability that a point chosen inside the large rectangle is not in the shaded region? 18% 36% 42% 64% Question 21 (Multiple Choice Worth 5 points) (06.02 LC) Jenny has some tiles in a bag. The tiles are of three different colors: purple, pink, and orange. Jenny randomly pulls a tile out of the bag, records the color, and replaces the tile in the bag. She does this 50 times. The results are recorded in the given table: Color of Tile Purple Pink Orange Number of times the tile is drawn 6 18 26 What is the experimental probability that Jenny will pull out a purple tile? fraction 6 over 50 fraction 44 over 50 fraction 6 over 44 fraction 18 over 44 Question 22 (Multiple Choice Worth 5 points) (06.05 MC) The teacher of a seventh-grade class flipped a coin 100 times. The students recorded the results in the table shown below: Side of Coin Landed On Heads Tails Number of Flips 56 44 Which of the following best describes the experimental probability of getting heads? The experimental probability is same as the theoretical probability. The experimental probability is 6% lower than the theoretical probability. The experimental probability is 6% higher than the theoretical probability. The experimental probability cannot be concluded from the data in the table. Question 23 (Multiple Choice Worth 5 points) (06.05 MC) The teacher of a seventh-grade class flipped a coin 100 times. The students recorded the results in the table shown below: Side of Coin Landed On Heads Tails Number of Flips 56 44 Which of the following best describes the experimental probability of getting tails? The experimental probability is same as the theoretical probability. The experimental probability is 6% lower than the theoretical probability. The experimental probability is 6% higher than the theoretical probability. The experimental probability cannot be concluded from the data in the table. Question 24 (Multiple Choice Worth 5 points) (06.02 MC) Jake has a bag of 50 beads, some of which are blue and the remaining are green. Jake randomly pulls out a bead from the bag, records the color, and replaces it in the bag. Jake has already recorded 16 blue and 4 green beads. Based on these results, what is most likely the number of blue beads in the bag? 10 20 30 40 Question 25 (Multiple Choice Worth 5 points) (06.04 LC) A vendor has 10 balloons for sale: 5 are yellow, 2 are red, and 3 are green. A balloon is selected at random and sold. If the balloon sold is yellow, what is the probability that the next balloon selected at random is also yellow? fraction 5 over 10 fraction 4 over 9 fraction 4 over 10 fraction 5 over 9 Question 26 (Multiple Choice Worth 5 points) (06.02 LC) A colored chip is yellow on one side and red on the other. The chip was flipped 50 times and landed on yellow side up 29 times. What is the relative frequency of the chip landing with the yellow side facing up? 38% 42% 56% 58% Question 27 (Multiple Choice Worth 5 points) (06.02 MC) Jake has a bag of 50 beads, some of which are blue and the remaining are green. Jake randomly pulls out a bead from the bag, records the color, and replaces it in the bag. Jake has already recorded 14 blue and 6 green beads. Based on these results, what is most likely the number of blue beads in the bag? 15 20 30 35 Question 28 (Multiple Choice Worth 5 points) (06.05 MC) A spinner has six sections of equal shape and size. Each section is either black or white. The table shows the result of an experiment when the spinner was spun 90 times: Result of Spin Black White Number of Spins 18 72 Based on the data, which of the following best describes the experimental probability of the arrow landing on a black or white section of the spinner? The spinner is equally likely to land on black or white. The spinner is 4 times more likely to land on white. The spinner is 4 times more likely to land on black. The information cannot be concluded from the data table. Question 29 (Multiple Choice Worth 5 points) (06.01 LC) A bowl contains candies of the same size in three flavors: orange, strawberry, and pineapple. If the probability of randomly pulling out an orange candy is fraction 1 over 9, and the probability of randomly pulling out a strawberry candy is fraction 2 over 9, what is the probability of randomly pulling out a pineapple candy? fraction 2 over 9 fraction 3 over 9 fraction 5 over 9 fraction 6 over 9 Question 30 (Multiple Choice Worth 5 points) (06.01 LC) At the school carnival, Jade has a game booth with a spinner. The banner at her booth reads "20% chance of winning!" What is the chance that a player may not win? 40% 50% 80% 90%
