tim has two spinners, spinner a and spinner b. each spinner can only land on red or blue. the probability that spinner a will land on is 0.5 and the pribability that spinner b will land on blie is 0.6. tim spins spinner a once and he spins spinner b once. he does this for a number of times.
the number of times both spinners land on red is 84. work out an estimate for the number of spinners land on blue.

1. what is the formula for finding the vertical distance between two points on a coordinate plane?

Polygons efgh and e′f′g′h′ are shown on the coordinate grid: what set of transformations is performed on efgh to form e′f′g′h′? a. a translation 1 unit to the left followed by a 90-degree counterclockwise rotation about the origin b. a translation 1 unit to the right followed by a 90-degree counterclockwise rotation about the origin c. a 90-degree clockwise rotation about the origin followed by a translation 2 units to the right d. a 90-degree clockwise rotation about the origin followed by a translation 2 units to the left

Which statement accurately explains whether a reflection over the x-axis and a 180° rotation would map figure acb onto itself?
