Sample space: tails/tails,tails/head,head/tails, head/head.
(the slash divides the first toss and the second toss)
P(head,head)=1/4
P(not tail,tail)=1-1/4=3/4
the probability is not the same.
This corresponds to a sinusoidal graph, we have:
Radius= 20 feet, that corresponds to the amplitud (A)
One revolution takes 24 seconds, that corresponds to the period
Min= 3 feet
k=360/24=15
D= bottom distance+ amplitud=3+20=23 feet
Then, let x be the time, in seconds:
a) To determine Reid's height after 1 minute= 60 seconds, substitute x=60
b) To determine when Reid's height will first reach 18 feet, we have to substitute y=18 feet, and isolate x:
account b has 2.6% more interest than account a
