Activity 5: Read and analyze the following problem to answer the question. The government launched Enhanced Community Quarantine on March 15, 2020, as a preventive measure to fight the spread of COVID-19 in the country. Many of us experienced difficulties in getting our daily needs like food or getting money to pay for our bills and rentals. Our government gave financial support and food, but it is not enough for the people. Fortunately, we are blessed because the spirit of love and generosity is still present in the heart of our fellow countrymen. They donated money, food, time, and other essential things. Suppose you and your friends conducted a donation-drive in your barangay. Each of the donors gave a certain amount with an average of Php 320.00 and a standard deviation of Php 60.00. Assuming, it is normally distributed, 1. What percentage of the distribution that the amount falls between Php. 260.00 and Php 380.00? 2. How much of the donations fall in 95% of the distributions? 3.…
A company manufactures a product at its plants in A, B, and C, then ships the product to six customers in G, H, J, K, and L, The monthly capacity of plants A, B, and Care 7400, 7300, and 10000 units, respectively. The monthly demand from customers G, H, J, K, and Lare 3000, 500, 4600, 7500, and 8900 units, respectively. Use Excel Solver to find the optimal distribution plant that will give the lowest total monthly shipping cost if the shipping cost per unit (in dollars per unit) are as follows: - from A to G, H, J, K, and L are 4, 9, 20, 6, and 13 dollars per unit, respectively; from B to G, H, J, K, and L are 12, 7, 3, 10, and 6 dollars per unit, respectively; from C to G, H, J, K, and L are 7, 6, 12, 2, and 9 dollars per unit, respectively. - The optimal total shipping costs is dollars per month.

Frogs have been breeding like flies at the Enormous State University (ESU) campus! Each year, the pledge class of the Epsilon Delta fraternity is instructed to tag all the frogs residing on the ESU campus. Two years ago (t = 0) they managed to tag all 42,000 of them (with little Epsilon Delta Fraternity tags). This year's pledge class discovered that all the tags had fallen off, and they wound up tagging a total of 63,000 frogs. (a) Find an exponential model for the frog population. f(t) = (b) Assuming exponential population growth, and that all this year's tags have fallen off, how many tags should Epsilon Delta order for next year's pledge class? (Round your answer to the nearest integer.) tags

(4) Assume that a website www.funwithmath1600.ag has three pages: Page A: KingAlgebra Page B: Learn1600andWin • Page C: Linear AlgbraIsEverywhere Each page has some links to the other pages of this website and no pages links to any page outside this website. Page A has three links to page B and only one link to page C. • Page B has three links to page A and two links to page C. • Page C has one link to page A and two links to page B. A student decides to explore this website starting from page A. Since reading content is always a boring task (is it?!) they decide to choose one of the links in page A with equal probability and click on the link to see the next page. As a result, on the next step, they will end up on page B with probability 3/4 and on the page C with probability 1/4. This process is then continued by the student with the same rule: Go the next page by clicking, with equal probability, on one of the existing links that are on the present page.
