Beanie owns a gas pump that is honest. When the pump reads 24 gallons of gas, you might not get exactly 24 gallons because of random variation, but on average it delivers 24 gallons. The standard deviation is 0.3 gallons. The government is going to do a random check on Beanie's gas pump. They will select 100 random times to fill up to where the gas pump says "24 gallons", and then in the lab they will measure it to...

Beanie owns a gas pump that is honest. When the pump reads 9 gallons of gas, you might not get exactly 9 gallons because of random variation, but on average it delivers 9 gallons. The standard deviation is 0.2 gallons. The government is going to do a random check on Beanie's gas pump. They will select 81 random times to fill up to where the gas pump says "9 gallons", and then in the lab they will measure it to...

A gasoline tank for a certain car is designed to hold 15 gallons of gas. Suppose that the actual capacity of a randomly selected tank has a distribution that is approximately Normal with a mean of 15.0 gallons and a standard deviation of 0.15 gallons. The manufacturer of this gasoline tank considers the largest 2% of these tanks too large to put on the market. How large does a tank have to be to be considered too large?

Please show all work. Suppose there is a tank of 100 gallons of a salt mixture with concentration 0.25 pounds per rate of 2 gallons per minute. It is well mixed and then drained out at the rate of 2 gallons per minute. A) Write a differential equation, in terms of only A and t, that models this situation, where A is the amount of salt in tank after t minutes. Include the initial condition. DO NO1T SOLVE THE DE!...

2. A tank contains 100 gallons of pure water. Beginning at t O, a salt water solution containing 0.2 pounds of salt per gallon is pumped into the tank at a rate of 3 gallons per minute. At the same time, a drain is opened at the bottom of the tank which allows the mixture to leave the tank at a rate 3 gallons per minute. Assume the solution is kept perfectly mixed. (a) What will be concentration of salt...

A tank contains 200 gallons of liquid. Five gallons of brine per minute flow into the tank, and each gallon of brine contains 2 pounds of salt. Five gallons of brine flow out of the tank per minute. Assume that the tank is kept well stirred. A. Find a differential equation for the number of pounds of salt in the tank. Assuming the tank intially contains 50 pounds of salt, solve this differential equation. B. How much salt is in...
