A bicycle wheel makes five rotations. The bicycle travels 41.87 ft. Find the diameter of the wheel in inches. Use 3.14 for pi. The diameter of the wheel is about nothing in.

The diameter is 32.04 Inches

Step-by-step explanation:

If the Bicycle makes 5 rotations and it equals 41.87 ft

Then 1 rotation around the circumference is

41.87/5 = 8.374 ft

Circumference =

8.374 = 3.14*d

Divide both sides by 3.14

d = 8.374/3.14

d = 2.67 ft

To convert feet to inches, we multiply by 12

d = 2.67*12 inches

d = 32.04 Inches

step-by-step explanation:

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.
