Which sequence of transformations would result in a figure that is similar, but not congruent, to the original figure?

Select all that apply.

[] a translation 2 units up followed by a rotation of 180 degrees about the origin
[] a dilation with a scale factor of 2 followed by a reflection across the x-axis
[] a reflection across the y-axis followed by a dilation with a scale factor of 0.5
[] a rotation about the origin of 25 degrees followed by a reflection across the y-axis

Suppose there are 10 five and six-year-old attending a birthday party. when a 30 year old mother walks into the room with an infant in her arms, what happens to the mean age in the room? what happens to the standard deviation of ages in the room? a. the mean and standard deviation of both change. b. the meaning will change, but the standard deviation will stay approximately the same. c. i mean will stay approximately the same, but the standard deviation will change. d. the mean and standard deviation will both stay approximately the same.

15 points! write the slope-intercept form of the equation of the line through the given point with the given slope. use y-y = m(x-x) to solve. through (2,5) slope= undefined
