In boot camp, a cadet must use a rope swing to cross an obstacle without
falling into the water hazard below. unfortunately, they miss the platform on
the other side and swing back to where they started. if it takes the cadet 5.5
seconds to swing from one side of the obstacle to the other and back, how
long is the rope swing? use the formula:
t=2011
o
a. 2.9 meters
o
b. 7.5 meters
o
c. 14.6 meters
o
d. 4.7 meters

Consider a bag that contains 220 coins of which 6 are rare indian pennies. for the given pair of events a and b, complete parts (a) and (b) below. a: when one of the 220 coins is randomly selected, it is one of the 6 indian pennies. b: when another one of the 220 coins is randomly selected (with replacement), it is also one of the 6 indian pennies. a. determine whether events a and b are independent or dependent. b. find p(a and b), the probability that events a and b both occur.
