A scientist working for the MDEQ measured the amount of bacteria present in a surface water sample. According to the scientist, the sample contains 3,600 MPN/100 mL total coliform and 56,700 MPN/100 E. coli. Can you trust the results? Explain your answer.
Homework Answers
Ans- one of the most common ways to test for bacteria is to culture the water sample in a vial with a chemical reactant. this process takes 48 hours. the sample tested by the scientist is approximately correct

At each ater is considered safe if it contains less than 130 E. Coli per 100 milliliters (mL) ater was tested at a random sample of 20 locations around a popular swimming location, the number of Coli present per 100 mL was measured to determine if the water was safe.

Water permeability of concrete can be measured by letting water flow across the surface and determining the amount lost (in inches per hour). Suppose that the permeability index x for a randomly selected concrete specimen of a particular type is normally distributed with mean value 1000 and standard deviation 150. (a) How likely is it that a single randomly selected specimen will have a permeability index between 850 and 1300? (Round your answer to four decimal places.) P(850 < x...

Now knowing the MPN value, you decide to do a dilution series in order to figure out the original bacterial concentration of the Swimming Hole, just in case it is not a coliform causing the gastric distress and simply a bacterial overgrowth. You perform the following dilution set: from your 16.3-liter Swimming Hole sample you transfer 10.7 x 10-3 liters into container A which has a volume of 6,250ul, you then transfer 1.7 mL from container A into container B...

a tank with 500 liters of water initially contains 4g of calcium. Water with a concentration of 3 mg/L is pumped into the tank at a rate of 1L/min and the mixture is pumped out at the same rate. (a) Write a differential equation and its initial condition for, y(t), the total amount of calcium in grams in the tank. (t is measured in minutes, 1g = 1000mg) (b) Find the general solution to this differential equation. (c) Find the...
