A chocolate factory produces 80,000 blocks of chocolate per day. Today, the factory operator wants to sample 2% of the blocks for quality testing. He uses a systematic sample, starting from the 17th block. a. List the first five blocks to be sampled
b. What is the size of the sample?
Please show all work to both parts of the question

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.

hope this
