A lower limit estimate for the amount of material leaked after 4 hours is gal. (Simplify your answer.) An upper limit estimate for the amount of material leaked after 8 hours is (Simplify your answer.) gal. A lower limit estimate for the amount of material leaked after 8 hours is gal. (Simplify your answer.) If the leakage occurs at a constant rate of 720 gal/hr after 8 hours and the tank initially held 20,000 gallons of material, an estimate for the least amount of time for the tank to empty is hr. (Round to the nearest tenth as needed.) If the leakage occurs at a constant rate of 720 gal/hr after 8 hours and the tank initially held 20,000 gallons of material, an estimate for the most amount…
During an annual physical, a doctor wants to determine not only the weight of her patients, but also the Body Mass Index (BMI). The BMI measures the ratio of weight to height. The formula for calculating BMI is:Where w = weight in pounds and h = height in inches. An adult whose BMI is: less than 18.5 is considered underweight, between 18.5 and 25 is considered normal weight, between 25 and 30 is overweight, and over 30 is considered obese.Determine which category an adult female who weighs 124 pounds and is 5 feet tall (60 inches) would be considered. A overweight B underweight C normal weight D obese
Medical studies of obesity use the Body Mass Index (BMI), which is defined by w BMI = where w is weight in kilograms and h is height in meters.
Determine whether the given value is a statistic or a parameter. A homeowner measured the voltage supplied to his home on a random sample of 48 days, and the average (mean) value is 122.9 volts. Choose the correct answer below. OA. The given value is a statistic for the year because the data collected represent a sample. OB. The given value is a parameter for the year because the data collected represent a population. OC. The given value is a parameter for the year because the data collected represent a sample. OD. The given value is a statistic for the year because the data collected represent a population.
In thermodynamics, the Van der Waal's equation relates the mean pressure, p, of a substance to its molar volume v at some temperature T as follows: when p = 5.2 and v = 2.9? Chemists are interested in the curves, called isotherms, described by this equation when the temperature is held fixed, and R is a constant.

Drinking water is treated with fluoride before it is made available to the public. The ideal level is 0.7 ppm. A 20,000 gallon mixing tank is half full and contains 2 lb of fluoride. Fresh water enters from the lake at 2 gallons per minute. If the tank is dis- charged at 1 gallon per minute, how many pounds of fluoride is in the tank the moment it is full? Is it safe to drink using the conversion 1 lb/gal (US) = 119826 ppm?
