A grocer receives cartons of 12 eggs in boxes of 100 cartons. In a particular month, the grocer receives 4 shipments of eggs with 20 boxes in each shipment. The grocer wants to estimate the proportion of cartons he receives this month that include at least one broken egg. Which of the following sampling methods would be most appropriate?A. Obtain a stratified sample by examining 100 randomly selected cartons from each of the 4 shipments. B. Obtain a cluster sample by randomly selecting 3 boxes and examining every carton in those 3 boxes. C. Obtain a convenience sample by examining every carton on the grocery store's shelves one day. D. Obtain a systematic sample by examining the top carton in the top right corner of each box.

if you are saying purchasing 3 social media ads and one newspaper ad counts as one purchase then there are:

6 purchases

if you are asking how many of each then:

18 social media ads

6 newspaper ads

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
