Use the Law of Syllogism to form a new conditional statement that follows from the pair of true statements. If BD−→− bisects ∠ABC, then ∠ABD≅∠CBD.

If ∠ABD≅∠CBD, then m∠ABD=12( m∠ABC).

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .

What expression is equivalent to (2x-1)(x-3)?

Aproduction manager test 10 toothbrushes and finds that their mean lifetime is 450 hours. she then design sales package of this type of toothbrush. it states that the customers can expect the toothbrush to last approximately 460 hours. this is an example of what phase of inferential statistics
