Determine the response of a mass-spring system when it is
subjected to a half-sine pulse of 250 dyne amplitude and 0.25?
seconds duration. The mass is 20gm and the spring stiffness is
197.4 dynes/cm.
What is the half-life (T1/2) of a radioactive element with the
following conditions?
-Initial Activity = 1000 milliCuries
-Final Activity = 400 milliCuries
-Elapsed Time= 20.0 days
What is Horvitz-Thompson estimator of population total? Give the
Yates-Grundy expression of its variance and obtain an unbiased
estimator of this variance. Show that this estimator of the
variance will never be negative under Midzuno-Sen sampling
scheme.
Lachlan has a Jacaranda growing in his yard. One of the tree
limbs is growing over into Dan’s property. Dan does not like this
and wants Lachlan to chop down the tree. Their respective benefits
are shown below: Keeping Tree Chopping Down TreeGains to Lachlan ($) 1000 500Gains to Dan ($) 100 1,006Total ($) 1100What is the amount that Dan would have to pay Lachlan so that
each received half of the total extra gains from chopping...
