Scores on the verbal Graduate Record Exam (GRE) have a mean of
453 and a standard deviation of 122. Scores on the quantitative GRE
have a mean of 651 and a standard deviation of 157. A perfect score
on either exam is 800. Assuming the scores are normally
distributed, what percentage of students score 800 on the
quantitative exam?
The percentage of students that score 800 on the quantitative
exam is approximately _% (Round to the nearest percent as
needed.)...

2. An FCC iron-carbon alloy initially containing 0.40 wt% C is exposed to an oxygen-rich and virtually carbon-free atmosphere at 1325 K (1052°C). Under these circumstances the carbon diffuses from the alloy and reacts at the surface with the oxygen in the atmosphere—that is, the carbon concentration at the surface position is maintained essentially at 0 wt% C. (This process of carbon depletion is termed decarburization.) At what position will the carbon concentration be 0.25 wt% after a 10-h treatment?...
