A fish is swimming at a constant rate toward the ocean floor. The equation y = -7x -3 can be used to represent this situation, where y is the depth of the fish in meters below sea level and x is the number of seconds the fish has been swimming.

Which statement best describes the depth of this fish, given this equation? (DOK 3)

A
From a starting position of 3 meters below sea level, the fish is going down( descending) 7 meters per second

B
From a starting position of 7 meters below sea level, the fish is ascending 3 meters per second

C
From a starting position of 7 meters below sea level, the fish is descending 3 meters per second

D
From a starting position of 3 meters below sea level, the fish is ascending 7 meters per second

An electronics manufacturer wants to know if customers would be interested in a detachable keyboard for their tables and if so, what the most important features would be. the manufacturer partners with an electronics store to include copies of the survey with every purchase at that store for one week. which of the following best explains why this random sample is unlikely to be a good representative sample of tablet owners' preferences for a detachable keyboard? a) one week is likely not enough time to get a large enough sample. b) most people won't bother to send in the survey, which is likely to skew the results c) there is no way to verify whether the responders to the survey actually own a tablet d) the survey is biased because it was conducted through an electronics store, not the general population
