"An activity of 1000 Bq of a class-W aerosol (AMAD = 1 micrometer) is inhaled in a single intake a) According to the ICRP-30 model for the respiratory system what is the initial activity deposited in compartment e. b) If the radionuclide has a physical half-life of 32 days, what fraction of the original activity in the compartment “e”, will still be there after 1 week. "

The mitochondrial ATP synthase is composed of multiple proteins, and some of these proteins are encoded by genes in the nucleus. One of these proteins is called S . A mutation in the S gene deletes 21 base pairs that are immediately 3’ to the start codon. The mutant S gene is transcribed and translated...

"Suppose that a learning curve us described by the function T(N) = 20/√N Where (T)n is the time in hours to produce the nth unit. a. How much time is required to produce the fourth unit. b. How much time is required to produce the first four units. c. If the cost of labor is $10 per hour, how much money does if cost the to produce the first four units. "

Construct a dot plot, box plot, and stem-and-leaf display to discuss any patterns in the data set. "

An experiment consists of flipping a fair coin three times and noting the number of heads and tails. A random variable x is defined to be two times the number of heads plus the number of tails. Find E(x), the expected value of x.
