Amanda and stephen wrote the following proofs to prove that vertical angles are congruent. who is correct? line segment nt intersects line segment mr forming four angles. angles 1 and 3 are vertical angles. angles 2 and 4 are vertical angles. amanda's proof statement justification ∠1 + ∠4 = 180° definition of supplementary angles ∠3 + ∠4 = 180° definition of supplementary angles ∠1 + ∠4 = ∠3 + ∠4 transitive property of equality ∠1 ≅ ∠3 subtraction property of equality stephen's proof statement justification ∠1 + ∠2 = 180° definition of supplementary angles ∠2 + ∠3 = 180° definition of supplementary angles ∠1 + ∠2 = ∠2 + ∠3 transitive property of equality ∠1 ≅ ∠3 subtraction property of equality

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:

Which statements are true about box plots? check all that apply. they describe sets of data. they include the mean. they show the data split into four parts. they show outliers through really short “whiskers.” each section of a box plot represents 25% of the data.
