The table shows the proof of the relationship between the slopes of two perpendicular lines. what is the missing statement in step 6? a) slope of ac x slope of dc= ec/dc x dc/ec b) slope of ac x -slope of dc=1 c) slope of ac x slope of dc=1 d) slope of ac x slope of dc=-ec/dc x dc/ec statement 1. ac←→⊥cd←→ (view diagram) δabc is similar to δced. 2. (this statement is intentionally left blank.) 3. abbc = ecde 4. slope of ac←→ = -abbc slope of dc←→ = deac 5. slope of ac←→ × slope of dc←→ = -abbc×deec 6. ? 7. slope of ac←→ × slope of dc←→ = -1 simplifying the right side reason 1. given 2. property of similar triangles 3. property of proportion 4. definition of slope 5. multiplying the slopes 6. substitution property of equality 7. simplifying the right side

For a science project, a high school research team conducted a survey of local air temperatures. based on the results of the survey, the found that the average temperatures were around 10 degrees higher than expected. this result was wrong. the trouble with the survey was that most of the locations were exposed to direct sunlight and located over asphalt or sand, which resulted in higher temperatures than normal. this is a classic example of an error in which phase of inferential statistics?
