The answer is the second one: root.

Explanation for each option:

  • Gingiva: This refers to the gums, which are the soft tissue surrounding the teeth, not a major region of the tooth itself.
  • Root: This is the correct answer. The root is the part of the tooth that is embedded in the jawbone, anchoring the tooth in place. It is one of the two major regions of a tooth, along with the crown.
  • Enamel: This is the hard, outer surface layer of the tooth that covers the crown. While it is a component of the tooth, it is not considered one of the two major regions.
  • Dentin: This is the layer beneath the enamel and cementum, forming the bulk of the tooth structure. Like enamel, it is a component of the tooth but not one of the two major regions.

Summary: A tooth consists of two major regions, the crown and the root.

Determine whether you can use a normal distribution to approximate the binomial distribution. If you can, use the normal distribution to approximate the indicated probabilities and sketch their graphs. If you cannot, explain why and use a binomial distribution to find the indicated probabilities. Identify any unusual events. Explain. In a survey of U.S. college students, 62% said that if their college offers new programs tailored to the new economy, it will make them more likely to re-enroll. You randomly select 41 college students. Find the probability that the number who are more likely to enroll if their college offers new programs tailored to the new economy is (a) exactly 25, (b) at least 30, and (c) at most 24. A. Yes, because both np ≥ 5 and nq ≥ 5. B. No, because nq<5. C. No, because np<5. (a) Find the probability that the number who are more likely to enroll if their college offers new programs tailored to the new economy is exactly 25. (Round to four decimal places as needed.)

Based on data from a car bumper sticker study, when a car is randomly selected, the number of bumper stickers and the corresponding probabilities are as shown below. Complete parts (a) through (d). a. Does the given information describe a probability distribution? Yes No b. Assuming that a probability distribution is described, find its mean and standard deviation. The mean is (Round to the nearest tenth as needed.) The standard deviation is 1.4 (Round to the nearest tenth as needed.) c. Use the range rule of thumb to identify the range of values for usual numbers of bumper stickers. The maximum usual value is (Round to the nearest tenth as needed.) The minimum usual value is (Round to the nearest tenth as needed.)
