The least-squares regression equation ý = 3 + 1.16x can be used to predict the height of a plant
(in centimeters) after x weeks. Suppose the height of a
plant was 9.2 centimeters after 5 weeks.
Calculate and interpret the residual for this plant after 5
weeks.
The residual is y, which means that the predicted
height of the plant is
than the
actual height of the plant of centimeters

Triangle jkl is transformed to create triangle j'k'l'. the angles in both triangles are shown. j = 90° j' = 90° k = 65° k' = 65° l = 25° l' = 25° which statement is true about this transformation? it is a rigid transformation because the pre-image and image have the same corresponding angle measures. it is not a rigid transformation because the corresponding side lengths are not equal. it can be a rigid or a nonrigid transformation depending on whether the corresponding side lengths have the same measures. it can be a rigid or a nonrigid transformation because a pair of corresponding angles measures 90°.
