R - radius of the larger circle
r - radius of the smaller circle
Circumference of the larger circle =

Circumference of the smaller circle =

Part 2: During one complete rotation of the larger gear both gears pass the same distance

.
Therefore, the smaller gear makes

complete rotations.
Part 1: During one complete rotation of the smaller gear both gears pass the same distance

.
Therefore, the larger gear makes

of a complete rotation.
Since one complete rotation corresponds to 360 degrees, 1/4 of a complete rotation corresponds to 360/4=90 degrees.
Answer: Approximately normal, because we expect 19.2 successes and 20.8 failures from people in their twenties, and 16.8 and 43.2 from people in their fifties, and all of these counts are at least 10.

Answer:
154 pounds
Step-by-step explanation:
If h=68, then w=5.5(68)-220=374-220=154
*edit I meant to write m^3/2
m^2/3 because its a cubed root.
