The process of making the impedance values on either side of a boundary as close as possible to reduce reflections is called:

Ultrasound xdcr convert _________ energy into ______ energy and vice versa.

The impedance of a xdcr’s matching layer is 2.6 MRayls and the impedance of the piezoelectric crystal is 3.4 MRayls. If this is assumed to be a good imaging system, what is the best estimate for the impedance of the skin?

The graph of the function f(x) is shown below.  

The piezoelectric crystal transforms:

Is it possible to predict whether a student smoke (Y/N) based on whether their father and mother smoke (Y/N) ? Data from a survey conducted on high school seniors and college students in Florida and Georgia was used to perform the logistic regression analysis whose results appear below : Predictor  Coef  Se Coef  Z P-value Constant -1.83 0.08 -22.875 0 Father Smoke 0.46 0.09 5.11 0 Mother Smoke 0.72 0.21 3.42 0.0006 Find the probability that a student will be a smoker in this population if his/her mother is not a smoker but father is a smoker.(1 = YES / 0 = NO)
