Design a recursive algorithm called Extrema (, p, ) that, given an array [1⋯] finds and returns both the min and max of the subarray [p⋯] as an ordered pair: (min([p⋯]), max([p⋯])). Your algorithm should perform exactly ⌈3/2⌉−2 array comparisons on an input array of length . (Hint: Section 9.1 of the text describes an iterative algorithm that does this.)

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.

Choose the equation that represents the graph below: (1 point) graph of a line passing through points negative 3 comma 0 and 0 comma 3 y = x − 3 y = −x + 3 y = −x − 3 y = x + 3 will award !
