Document Summary

Problem 1: particular mix are given as 60. 14 and 5. 02 . We need to find the value of x which satisfies the condition. Hence satisfies the condition [matlab command: norminv(0. 05)=-1. 645] strength of 45 or less? with sample estimates and values of random variables, we find (b) what is the probability that a test cube will fail when subjected to a compressive. For the assumed n(60. 14, 5. 02) population, one obtains. Although this value is close to zero, an engineer may decide to adopt a lower design value, particularly if there is doubt about quality control on-site. The probability is the area under the curve between the two vertical lines in the below figure. Settlement of bridge foundations a proposed bridge across a stream is supported at the two ends and on a center pier. Although the design allows for relative settlements of the foundations, the engineer needs to keep these within limits.
