Answer:
P=1/65.
Step-by-step explanation:
We knaow that one coin in a collection of 65 has two heads. If a coin, chosen at random from the lot and then tossed, turns up heads 6 times in a row. We calculate the probability that it is the two-headed coin.
We calculate the number of possible combinations:

Number of favorable combinations is 1.
Therefore, the probability is
P=1/65.
Answer:
g(f(x)) = 10x^2 - 18
Step-by-step explanation:
g(f(x)) = 5(2x² - 5) + 7
g(f(x)) = 10x² - 25 + 7
g(f(x)) = 10x² - 18
(or g(f(x)) = 10x² + (-18), to fit your answer format)
That would be the first choice:
5^0 = 1 , 5^1 = 5, 5^2 = 25 and so on up to 5^4 = 625
