Suppose h, a, h,a, and bb are positive real numbers, and t_0, y_0t 0 ,y 0 are real numbers, and that f(t, y)f(t, y) is a function of tt and yy. Let t_n, ynt n ,y n satisfy the recursions t{n+1}=tn+h, \text{ and } \ y{n+1}= y_n+h f(t_n, y_n).t n+1 =t n +h, and y n+1 =y n +hf(t n ,y n ). Let RR be the rectangle in the tyty-plane given by: t_0\leq t\leq t_0+ at 0 ≤t≤t 0 +a, y_0- b\leq y\leq y_0+ by 0 −b≤y≤y 0 +b, and assume that |f(t, y)|\leq M∣f(t, y)∣≤M for all (t, y)(t, y) in RR. Finally, let \alpha = \min(a, b/ M)α=min(a, b/M). a) Prove that |y_j-y_0| \leq jhM∣y j −y 0 ∣≤jhM, as long as jh \leq \alphajh≤α. b) Conclude from (a) that the points (t_j, y_j)(t j ,y j ) all lie in RR as long as j \leq \alpha/h. j≤α/h

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.
