Answer:
Step-by-step explanation:
The formula for the circumference of a circle in terms of diameter is ...
C = πd
Then the diameter is ...
d = C/π
If we use π ≈ 22/7 and C = 66 ft, then we find the diameter to be ...
d = (66 ft)/(22/7) = (66 ft)(7/22) = 21 ft
The diameter of the pool is about 21 feet.

Since Carlos needs 4 more feet of rope, he will want to buy 25 feet of rope for a cost of ...
(25 ft)($0.45 /ft) = $11.25

Answer:
See below in bold.
Step-by-step explanation:
For the fair coin Prob(head) = 1/2 and Prob(Tail) = 1/2.
For the biased coin it is Prob(head) = 2/3 and Prob(Tail) = 1/3.
a) Prob(2 heads) = 1/2 * 2/3 = 1/3.
b) Prob(2 tails) = 1/2 * 1/3 = 1/6.
c) Prob(1 head ) = Prob(H T or T H) = 1/2 * 1/3 + 1/2 * 2/3) = 1/6+1/3 = 1/2.
d) Prob (at least one head) = prob (HH or TH or HT) = 1/3 + 1/2 =<em> </em>5/6.
