Lester thinks that the solution of any inequality with a > sign is the region above the line and the solution of any inequality with a < sign is the region below the line. Is Lester correct? Explain why or why not.
Sketch the region that corresponds to the given inequalities. x + y ≥ 4 x ≤ 8 y ≤ 8 x ≥ 0, y ≥ 0 Say whether the region is bounded or unbounded. The region is bounded.The region is unbounded. Find the coordinates of all corner points (if any). (Order your answers from smallest to largest x, then from smallest to largest y. If an answer does not exist, enter DNE.) (x, y) = (x, y) = (x, y) = (x, y) = (x, y) =

The Waterfall Buffet in the lower level of the National ArtGallery serves food cafeteria-style daily to visitors andemployees. The buffet is self-service. From 7:00 A.M. to9:00 A.M. customers arrive at the buffet at a rate of eight perminute; from 9:00 A.M. to noon, at four per minute; from noon to 2:00, at 14 per minute; and from 2:00 P.M. to clos-ing at 5:00 P.M., at eight per minute (Poisson distributed). All the customers take about the same amount of time to serve themselves and proceed to the buffet. Once a cus-tomer goes through the buffet, it takes an average of 0.4 minute (exponentially distributed) to pay the cashier.The gallery does not want a customer to have to wait longerthan four minutes to pay. How many cashiers should beworking at each of the four times during the day?
Show Detailed SolutionFor a cooking oil company, the price they are paid for coconuts in large shipments is based on the amount of coconut extract from the load. Therefore, there is a need to determine the amount of coconut extract in the whole load prior to extraction. A sample of n coconut can be taken and find y1, . . . , yn , the amount of coconut extract in these coconuts. Nȳ is hard to get in this case because N is hard to count. How can the total amount of coconut extract from a load shipment be measured? Using the total weight would be a good idea and easy to obtain. The relationship between the weight of the load and the weight of the coconut extract one obtains can be used. As it turns out, 15 coconuts selected by simple random sampling were weighed and also extracted. The total weight of the coconut shipment was found to be 900 kg. Given these results (below):Use a ratio estimator to estimate the total weight of the coconut extract for this shipment of coconuts.…

Shade the area that satisfies the following system of inequalities y>n,x≥-n+1,y<-x+2n where n is your arid number for example if your arid number is 19-arid-607 then take n=607.
Boris will donate up to $460 to charity. The money will be divided between two charities: the City Youth Fund and the Educational Growth Foundation. Boris would like the amount donated to the Educational Growth Foundation to be at least twice the amount donated to the City Youth Fund. Let x denote the amount of money (in dollars) donated to the City Youth Fund. Let y denote the amount of money (in dollars) donated to the Educational Growth Foundation. Shade the region corresponding to all values of x and y that satisfy these requirements.

A filter removes 75% of the impurities of water that is passes throught it. Multiple filters can be used together to increase the purity of the water. This situation is represented by A=0.25^N, where A is the proportion of impurities remaining and n is the number of filters used. What proportion of impurities remians when four filters are used, to the nearest ten thousandth? Explain
