Well, we can break this down into a few steps. First off, if we split these 600 students up into groups of 10, we're doing 600/10 groups, or 60 groups total. Then, if we randomly pick one student from each group, in total, we're surveying 60 students.
This is also an example of "stratified sampling". But that part's more of just knowing the vocabulary for statistics. Hope this helps!
1250. Cubic feet = volume and volume is length * width * height. The volume of this would be 5x5x(1/2), which equals 12.5 cubic feet. 12.5*100=1250
Well what’s the question asking. And if that’s all then good for the board

Answer:
. (In this problem we prove a fact that you demonstrated experimentally in Problem1 of the fourth assignment.) LetABCDbe a quadrilateral. LetM, N, P,andQbe the midpoints of the sides. Prove the area ofMNPQis one half the area ofABCD.4. (See Figure 1.) Give the proof of Theorem 24 for Case (iii). Given:MandNarethe midpoints ofABandAC,MX⊥AB,NX⊥AC, andXis onBC. To prove:Xis on the perpendicular bisector ofBC.XNCMABFigure 1
5. (See Figure 2). Prove Case (ii) of Theorem 28. Given:A0,B0andC0are collinear.To prove:A0BA0CB0CB0AC0AC0B= 1.C'A'B'ABCFigure 26. (See Figure 3.)Given:6A=6B,AD=BE,6ADG=6BEF.To prove:6CFE=6CGD.FGECDBAFigure 37. Suppose that you have a computer program which can perform the following func-tions:
(a) It can draw points, and draw line segments connecting two points.(b) Given a pointOand a line segmentAB, it can construct the circle with centerOand radius equal to the length ofAB.(c) Given a line segmentAB, it can find the midpoint.(d) Given a lineland a pointP(not necessarily lying onl), it can construct theline throughP
