"A freshly prepared solution of α-D-glucose shows a specific rotation of +112∘. Over time, the rotation of this solution decreases and reaches an equilibrium value of +52.5∘. In contrast, a freshly prepared solution of β-D-glucose has a specific rotation of +19∘. The rotation of this...

Suppose the scores, x, on a college entrance examination are normally distributed with a mean of 550 and a standard deviation of 100. A certain prestigious university will consider for admission only those applicants whose scores exceed the 90th percentile of the distribution. Find the minimum score an applicant must achieve in order to receive consideration to the university.

A swimming pool is 20ft wide and 34ft long, 6ft deep at the shallow end and 9ft deep at its deepest point. A cross-section is shown in the figure. If the pool is being filled at a rate of 0.75ft3/min, how fast is the water level rising when the depth at the deepest point is 2ft?

Suppose x is a normally distributed random variable with µ = 10 and σ = 2. Find P (5 ≤ x ≤ 9)

"Among Orthodox Jews, families are expected to be large.  Among Ashkenazim, a segment of the Jewish population, Tay-Sachs disease is [TSD] a relatively common disorder.  TSD is an inherited autosomal recessive disorder, i.e., both parents must be carriers in order that a child inherits...

"The budgeting process for a Midwestern college resulted in expense forecasts for the coming year (in $ millions) of $9, $10, $11, $12, and $13. Because the actual expenses are unknown, the following respective probabilities are assigned: .3, .2, .25, .05, and .2. a.    Show the...

The production function for a product is given by q = KL.  If the price of capital is $10 per day and the price of labor $15 per day, what is the minimum cost of producing 300 units of output?

"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...
