Ab is parallel to cd. cd is rotated 180°. which statement describes the relationship between c'd' and the transformed ab? how can you prove it? a) c'd' intersects ab; graph the points to find the point of intersection. b) c'd' || ab; use the slope formula to prove that the segments have the same slope. c) c'd'≠ab; use the distance formula to prove that the segments are not the same length. d) c'd' ⊥ ab; use the slope formula to prove that the segments have opposite reciprocated slopes.

Astudy was interested in determining if eating milk chocolate lowered someone's cholesterol levels.ten people's cholesterol was measured. then, each of these individuals were told to eat 100g of milk chocolate every day and to eat as they normally did. after two weeks, their cholesterol levels were measured again. is there evidence to support that their cholesterol levels went down? how should we write the alternative hypothesis? (mud = the population mean difference= before - after)a. ha: mud = 0b. ha: mud > 0c. ha: mud < 0d. ha: mud does not equal 0

If the car had not hit the fence, how much farther would it have skidded? solve the skid-distance formula to find the extra distance that the car would have traveled if it had not hit the fence. round your answer to two decimal places. note that unit conversion is built into the skid distance formula, so no unit conversions are needed.
