the insructions for a model car show a scale of 1 inch to 48 inches. How long is the actual car if the drawing is 4 inches

192

Step-by-step explanation:

The ratio of inches to inches is 1:48

To get 4:x

You have to multiply, 4/1 = 4, 4 by 48.

4*1 = 4

4*48 = 192

4:192 = 1:48 * 4

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.
