# Question 13(Multiple Choice Worth 1 points) (02.04 MC) Below is a two-column proof incorrectly proving that the three angles of APQR add up to 180°: Statements Reasons QRY = PQR Alternate Interior Angles Theorem Draw line ZY parallel to PQ Construction mZZRP + m_PRQ + m2QRY = m_ZRY Angle Addition Postulate ZRP = RPQ Alternate Interior Angles Theorem mZRPQ + m_PRQ + m_PQR = m_ZRY Substitution mZRY = 180° Definition of a Straight Angle m RPQ+m_PRQ + m_PQR = 180° Substitution Which statement will accurately correct the two-column proof? The measure of angle ZRY equals 180° by definition of supplementary angles. Angles QRY and PQR should be proven congruent after the construction of line ZY. The three angles of APQR equal 180according to the Transitive Property of Equality. Line ZY should be drawn parallel to segment QR.​  Answers: 2  ### Another question on Mathematics Mathematics, 21.06.2019 16:00

In tossing one coin 10 times, what are your chances for tossing a head? a tail? 2. in tossing one coin 100 times, what are your chances for tossing a head? a tail? 3. in tossing one coin 200 times, what are your chances for tossing a head? a tail? deviation = ((absolute value of the difference between expected heads and observed heads) + (absolute value of the difference between expected tails and observed tails)) divided by total number of tosses. this value should always be positive. 4. what is the deviation for 10 tosses? 5. what is the deviation for the 100 tosses? 6. what is the deviation for 200 tosses? 7. how does increasing the total number of coin tosses from 10 to 100 affect the deviation? 8. how does increasing the total number of tosses from 100 to 200 affect the deviation? 9. what two important probability principles were established in this exercise? 10. the percent of occurrence is the obtained results divided by the total tosses and multiplied by 100%. toss the coins 100 times and record your results. calculate the percent occurrence for each combination. percent head-head occurrence: percent tail-tail occurrence: percent head-tail occurrence:
