When studying radioactive​ material, a nuclear engineer found that over 365​ days, 1,000,000 radioactive atoms decayed to comma 970,128 radioactive​ atoms, so 29,872 atoms decayed during 365 days.

a. Find the mean number of radioactive atoms that decayed in a day.

b. Find the probability that on a given​ day, 50 radioactive atoms decayed.

Radioactive atoms are unstable because they have too much energy. When they release their extra energy, they are said to decay. When studying a particular radioactive element, it is found that during the course of decay over 365 days, 1,000,000 radioactive atoms are reduced to 986,949 radioactive atoms. Find the mean number of radioactive atoms lost through decay in a day. mean = Find the probability that on a given day 30 radioactive atoms decayed. P(X = 30) =

A local service station is open 7 days per week, 365 days per year. Sales of 10W40 grade premium oil average 25 cans per day. Inventory holding costs are $0.90 per can per year. Ordering costs are $7 per order. Lead time is two weeks. Backorders are not practical—the motorist drives away. a. Based on these data, calculate the economic order quantity and reorder point. Hint: Assume demand is deterministic. (Round your answers to the nearest whole number.)   Economic order...

For many florists, the days leading up to Valentine's Day are among the busiest of the year. An owner of a florist wanted to estimate the average sale amount for all sales made on the day before Valentine's Day, February 13th. When she had time she wrote down the sale price of a transaction of fresh flowers on a sheet of paper. By 3pm she had collected n=41 sale prices of all flower sales that were made day. The variable...
