Trees on a tree farm are only measured every three years. You cannot assume the measurements for each year. 1. Amy says that the heights of each tree display arithmetic sequences. Explain mathematically that Amy is correct.

2. Greg says the the heights of each tree display geometric sequences. Explain mathematically that Greg is correct.

3. What additional information about the tree heights would you need to know in order to say with confidence that the sequences of heights are either geometric or arithmetic?

Jeffery conducted a survey in his school and found that 30 of the 50 eighth grade students' favorite subject is mathematics. based on the results, jeffery concluded that out of the 200 students in his school, 120 students' favorite subject is mathematics. select the statement that is true about jeffery's conclusion. a. jeffery's conclusion is not valid because the sample was biased since only 200 students were surveyed. b. jeffery's conclusion is valid because the sample was random since all of the students were eighth grade students. c. jeffery's conclusion is valid because the sample was random. d. jeffery's conclusion is not valid because the sample was biased since all of the students were eighth grade students.

Two positive integers are 3 units apart on a number line. their product is 108. which equation can be used to solve for m, the greater integer? m(m – 3) = 108 m(m + 3) = 108 (m + 3)(m – 3) = 108 (m – 12)(m – 9) = 108

Select all the statements that apply to this figure
