Answer:
A definition and a theorem can be used as a reason in a two-column proof. A two column proof is assembled into statement and reason columns, where each statement should have verified reason.
Step-by-step explanation:
Answer:
∠ U = 60°
Step-by-step explanation:
The tangent- tangent angle U is half the difference of its intercepted arcs
minor arc VT = 120° , then
major arc VT = 360° - 120° = 240°
Then
∠ U =
(240 - 120)° =
× 120° = 60°
Answer:
Parameter
Step-by-step explanation:
Parameter and statistic:
- Parameter is a numerical value that describes a population.
- A sample is a part of the population and always smaller than the population.
- The statistic is a numerical value that describes a sample.
Population of interest:
College students aged 18 to 22
Parameter:
66.4% reported using alcohol within the past month
Thus, the given is a parameter as it describes a population proportion.
Well the question says "rewrite each statement using symbols so I guess it means using symbols...
Question 1:
Conclusion: ∠DAY + ∠YAK = 180°
Justification: definition of linear pair
Question 2:
Conclusion: Point U is the midpoint of RN
Justification: RU=UN, definition of midpoint
Question 4:
Conclusion: ∠3 = ∠7
Justification: definition of alternate interior angles
Question 5:
Conclusion: ∠ABD = ∠DBC
Justification: definition of bisector
Question 6:
Conclusion: ∠2 and ∠3 are supplementary angles
Justification: definition of supplementary angles
Sorry question 3, don't know what it's trying to say
