In ΔABC shown below, Line segment AB is congruent to Line segment BC: Triangle ABC, where sides AB and CB are congruent Given: line segment AB≅line segment BC Prove: The base angles of an isosceles triangle are congruent. The two-column proof with missing statement proves the base angles of an isosceles triangle are congruent: Statement Reason 1. segment BD is an angle bisector of ∠ABC. 1. by Construction 2. ∠ABD ≅ ∠CBD 2. Definition of an Angle Bisector 3. 3. Reflexive Property 4. ΔABD ≅ ΔCBD 4. Side-Angle-Side (SAS) Postulate 5. ∠BAC ≅ ∠BCA 5. CPCTC Which statement can be used to fill in the numbered blank space? please I need help NOW ASAP THANK YOU

Apoll is being conducted at a mall nothingto obtain a sample of the population of an entire country. what is the frame for this type of​ sampling? who would be excluded from the survey and how might this affect the results of the​ survey? what is the frame for this type of​ sampling? a. the frame is people who need new clothes. b. the frame is people who shop at the mall. c. the frame is people who like to shop. d. the frame is the entire population of the country. who would be excluded from the survey and how might this affect the results of the​ survey? a. any person that does not need new clothes is excluded. this could result in sampling bias due to undercoverage. b. any person who does not shop at the mall is excluded. this could result in sampling bias due to undercoverage. c. any person who does not shop at the mall is excluded. this could result in nonresponse bias due to people not participating in the poll. d. there is nobody that is being excluded from the survey.
