Problem 1: An object in the Cosmos Mystery Area in Rapid City, South Dakota appears to travel up a board. It initially travels at a
speed of 9 meters per second, and it speeds up at a constant rate of 2 meters per second each second. Under such
conditions, the distance d, in meters, that the object travels is given by the equation d = +2 +9t, where t is in seconds.
According to this equation, how long will it take the object to travel 22 meters?

O A) It will take the object 2 seconds to travel 22 meters.
OB) It will take the object -11 seconds to travel 22 meters.
OC) It is impossible for the object to travel anywhere in 22 meters (there are no real solutions).

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

what is the original number? you forgot to add it.

52 \43 i don't know this i tried
