Let A-B-C denote B is between A and C. For this problem, use the following three...
(1) Assume the axioms of metric geometry. Let A, B, C, D be distinct collinear points. Let f : l → R be a coordinate function for the line l that crosses all of A, B, C, D. Suppose f(A) < f(B) < f(C) < f(D). Prove that AD = AB ∪ BC ∪ CD. (2) Assume the axioms of metric geometry. Let A, B, C, D be distinct collinear points. Suppose A ∗ B ∗ C and B ∗...
Let A, B, C, and D be four distinct points in the plane. Suppose that no three of them lie on a line and A, C are on opposite sides of the line BD. The lengths of the line segments AB, BC, CD and DA are 1, 2, 3 and 4 respectively. (a) What is the range of possible values for the length x of the line segment BD? You should justify your answer carefully! [5 marks] (b) Now suppose...
Let A, B, and C be three collinear points s.t. A*B*C. Prove each of the follow set equalities. I'm really having trouble applying theorems like the ruler placement postulate or betweenness theorem to help prove these. 24. Let A, B, and C be three collinear points such that A * B * C. Prove each of the following set equalities. (a) BÁ U BỎ "АС (b) BA n BC {B} (c) ABU BC AC (d) AB n BC {B} (e)...
Question 1 (1 point) A line segment AD, contains points B & C such that C is between A and D, and B is between A and C. If AB- 6, BD- 23, and AB -CD, find the length of segment BC. 17 23 29 Not enough information to solve the problem
Let A, B, C be three collinear points and let D, E, F be the midpoints of segments AB, BC, and AC, respectively. Prove that the segments DE and BF have the same midpoint. Let d be a line and let A, B, C be three points not on d. Prove that if d does not separate points A and B and it does not separate points B and C, then it does not separate points A and C.
4. A certain system can experience three different types of defects. Let Ai(i= 1,2,3) denote the event that the system has a defect of type i. Suppose that: P(A1) = 0.12, P(A2) = 0.07, P(A3) = 0.05, P(A1∪A2) = 0.13, P(A1∪A3) = 0.14, P(A2∪A3) = 0.10, P(A1∩A2∩A3) = 0.01. (a) What is the probability that the system does not have a type 1 defect? (b) What is the probability that the system has both type 1 and type 2 defects?...
A certain system can experience three different types of defects. Let A; (i = 1,2,3) denote the event that the system has a defect of type i. Suppose that the following probabilities are true. P(A1) = 0.19 P(A2) = 0.14 P(A3) = 0.13 P(A1 UAZ) = 0.27 P(A1 UA3) = 0.27 P(A2 U A3) = 0.22 P(A1 A2 A3) = 0.02 D 0.22 (a) What is the probability that the system does not have a type 1 defect? (b) What...
3. Let G be a group containing 6 elements a, b, c, d, e, and f. Under the group operation called the multiplication, we know that ad = c, bd = f, and f2 = bc = e. We showed you in class that the identity is e, hence the e-row and e-column were revealed. Using associativity, we also found cb, cf, af, and a2. Now try to imitate the idea and find five more entries. Justify your answer. Hint:...
my choices for these are wrong. 10 points QUESTION 3 Given R=(A, B, C) is a schema and F = {2C-A AB) is a set of FDs that hold on R. Which of the following statements is not true? d=(AB. AC) is a decomposition of that is in BCNF. O Ris in 3NF O BC is a candidate key for R Ris in BCN 10 points QUESTION 4 Given R= (A. 3. CD. E) is a schema and F= (A...
A certain system can experience three different types of defects. Let A; (i = 1,2,3) denote the event that the system has a defect of type i. Suppose that the following probabilities are true. P(A1) = 0.11 P(A2) = 0.08 P(A3) = 0.05 P(A1 U A2) = 0.13 = 0.13 P(A2 U A3) = 0.11 P(An Azn Az) = 0.01 P(A1 UA3) (a) Given that the system has a type 1 defect, what is the probability that it has a...
