1:8 since if you simplify both sides by 23, 23/23 =1 and 184/23 = 8
Answer:
{ (HHHH) (HHHT) (HHTH) (HTHH) (THHH) (HHTT) (HTTH) (TTHH) (HTHT) (THTH) (THHT) (TTTH) (TTHT) (THTT) (HTTT) (TTTT) }
P(first and last head) = 4/16 = 1/4
Ack sorry the answer I put was probably wrong
area = pi x r^2
615.75 = 3.14 x r^2
r^2 = 615.75/3.14 =196.0987 round to 196.1
r = sqrt(196.1) = 14.00357 round to 14
radius = 14 kilometers
If we substitute 10 for t we get the height of the balloon after being in the air 10 minutes
h(10) = 210 - 15(10) = 210 - 150 = 60
