Fish is a rich source of protein and omega-3 fatty acids. However, some fish, such as shark, swordfish, and tuna, contain high concentrations of methylmercury and should be eaten only in moderation. For example, suppose a man starts a new diet in which he consumes 425 grams of albacore tuna per week (roughly equivalent to three 5 oz cans). His body will absorb about 145 micrograms
(a) Find an initial-value problem whose solution is
(b) Find a formula for y(t).
(c) Suppose the man weighs 160 lb. According to U.S EPA guidelines, the amount of methylmercury within his body should be at or below

- What is a carrying capacity? What kind of model has a carrying capacity built into its formula? Why does this make sense?arrow_forwardAs humans we consume food. The body extracts good things such as proteins and vitamins and throws away waste. A typical waste product is uric acid. High levels of uric acid can be an indication of conditions such as gout, kidney disease, and cancer. For females a high level of uric acid is 6 mg/dL or more and for males a high level of uric acid is 7 mg/dL or more. Suppose, over a period of months, an adult male has taken 8 blood test for uric acid.

Since lichen is a major source for Alaskan caribou, and caribou is major food source tor the Alaskan villagers, it is important to monitor the level of radioactivity in lichen. Researcher at the University of Alaska, Fairbanks, collected 9 lichen specimens and measured the amount in micro-curies per milliliter) of the radioactive element cesium-137 for each. Using the Minitab software, it was found that the mean and standard deviation for the 9 observations were X = 0.009027 аnd s = 0.004854 A) Give a point estimate for the mean amount of cesium in lichen specimens collected in Alaska.

- To investigate water quality, the Columbus Dispatch took water specimens at 16 Ohio State Park swimming areas in central Ohio. Those specimens were taken to laboratories and tested for E. coli, which are bacteria that can cause serious gastrointestinal problems. For reference, if a 100-milliliter specimen (about 3.3 ounces) of water contains more than 130 E. coli bacteria, it is considered unsafe. The E. coli levels per 100 milliliters found by the laboratories are presented in the table: 291.0 10.9 47.0 86.0 44.0 18.9 1.0 50.0 190.4 45.7 28.5 18.9 16.0 34.0 8.6 9.6 To access the complete data set, click the link for your preferred software format: Excel Minitab JMP SPSS TI R Mac-TXT PC-TXT CSV CrunchIt!

It is believed that this causes eggshells to be thinner and weaker than normal and makes the eggs more prone to breakage. An experiment was conducted where 16 sparrow hawks were fed a mixture of 3 ppm dieldrin and 15 ppm DDT (a combination often found in contaminated prey). The first egg laid by each bird was measured, and the mean shell thickness was found to be 0.19 mm. A “normal” eggshell has a mean thickness of 0.2 mm.

This occurs when holding tanks are replenished and the remaining portion of a lot is insufficient to fill the tanks. Only 5% of batches with material from a single lot require reprocessing. However, the viscosity of batches consisting of two or more lots of material is more difficult to control, and 40% of such batches require additional processing to achieve the required viscosity. Let A denote the event that a batch is formed from two different lots, and let B denote the event that a lot requires additional processing. Determine the following probabilities: а. Р(А) e.

It is decided to distribute at least 30,000 yogurts. Every lemon yogurt needs for its elaboration 0.5 gr. of a fermentation product and each strawberry yogurt needs 0.2 gr. of that same product. It has 9 kgs. of that product for fermentation. The cost of producing a yogurt of strawberry is twice that of a lemon yogurt. How many yogurts of each type must be produced so that the cost of the campaign is minimal?.arrow_forwardThe body needs vitamin D in order to use calcium. An experiment is designed to study the effects of calcium and vitamin D supplements on the bones of first-year college students. The outcome measure is the total body bone mineral content (TBBMC), a measure of bone health. Two doses of calcium will be used: 0 and 300 milligrams per day (mg/day). The doses of vitamin D will be 0 and 150 international units (IU) per day. The calcium and vitamin D will be given in a single tablet. All tablets, including those with no calcium and no vitamin D, will look identical. Subjects for the stud 20 d0n.man.
