I got my exam authorization with seat number today.

Had the following question on a sample exam recently. Q: A sample of steel originally 500 mm^2 in area reduces to 385 mm^2 immediately prior to failure in a tensile test. The sample's ductility, in percentage, is most nearly: A) 23 B 77 C) 100 D) 177 Solution does the calculation of...

That explains it! I assumed they were graphing the high point on each interval so it confused me. Thanks for the help!

That's what I found too and since 85 would be into the next speed range the 45 MPH answer seemed logical. In the solutions they graphed the frequency vs. the speed. However when they drew a horizontal line from 85% they didn't intersect the graphed information and called it 43.5 MPH and I was...

Took a practice exam today and had this question. Seemed pretty simple I didn't agree with the solution.. Q: The findings of a speed survey is summarized below Speed Interval (mph) Frequency 20 to 24 2 25 to 29 11 30 to 34 18 35 to 39 29 40 to...
