Michael and Derrick each completed a separate proof to show that corresponding angles AKG and ELK are congruent. Who completed the proof incorrectly? Explain. Line AB is parallel to EF, transversal GJ crosses line AB at K and crosses line EF at L. Michael's Proof Statement Justification 1. line AB ∥ line EF with transversal segment GJ 1. Given 2. angle AKG is congruent to angle AKL 2. Vertical Angles Theorem 3. angle BKL is congruent to angle ELK 3. Alternate Interior Angles Theorem 4. angle AKG is congruent to angle ELK 4. Transitive Property Derrick's Proof Statement Justification 1. line AB ∥ line EF with transversal segment GJ 1. Given 2. angle AKG is congruent to angle BKL 2. Vertical Angles Theorem 3. angle BKL is congruent to angle ELK 3. Alternate Interior Angles Theorem 4. angle AKG is congruent to angle ELK 4. Transitive Property Source StylesNormal

In a test for esp (extrasensory perception), a subject is told that cards only the experimenter can see contain either a star, a circle, a wave, or a square. as the experimenter looks at each of 20 cards in turn, the subject names the shape on the card. a subject who is just guessing has probability 0.25 of guessing correctly on each card. a. the count of correct guesses in 20 cards has a binomial distribution. what are n and p? b. what is the mean number of correct guesses in 20 cards for subjects who are just guessing? c. what is the probability of exactly 5 correct guesses in 20 cards if a subject is just guessing?
