The hoop hoe, also known as the action hoe, [17] [18] oscillating hoe, hula hoe, [18] stirrup hoe, [18] scuffle hoe, [18] loop hoe, [18] pendulum weeder, [19] or swivel hoe) has a double-edge blade that bends around to form a rectangle attached to the shaft.

Hoe-farming is a term introduced (as German: Hackbau; as opposed to Ackerbau) by Eduard Hahn in 1910 to collectively refer to primitive forms of agriculture, defined by the absence of the plough. Tillage in hoe-farming cultures is done by simple manual tools such as digging sticks or hoes .

In 1850, California was admitted to the union, and the process of separating privately held lands from the public domain began. The Williams claim to the Chino Rancho was patented in 1869.
Two variables are perfectly collinear if there is an exact linear relationship between the two, so the correlation between them is equal to 1 or −1. That is, X 1 and X 2 are perfectly collinear if there exist parameters λ 0 {\displaystyle \lambda _{0}} and λ 1 {\displaystyle \lambda _{1}} such that, for all observations i , we have
Simply, a collineation is a one-to-one map from one projective space to another, or from a projective space to itself, such that the images of collinear points are themselves collinear. One may formalize this using various ways of presenting a projective space. Also, the case of the projective line is special, and hence generally treated ...
