In scientific notation, you must move the "invisible decimal point" until there is a one-digit number, sometimes followed by a decimal of more numbers. Then, how ever many digits you had to move it is the exponent to the number 10.
Example:
1200.
120.0
12.00
1.200
Since the decimal had to move 3 places, the scientific notation of this is:
1.2 • 10^3
In this question, the decimal must move 9 places left before resulting in 1.322.
So the answer, in scientific notation, is 1.322 • 10^9.
Answer:
P = 0.075 P = 7.5%
Step-by-step explanation:
We pretty much look for the probability that the player fails the first attempt and also fails the second attempt.
We know for a fact that the probability that the quarterback fails the first attempt is:
p(1) = 0.5
and we know that the probability that the quarterback fails the second attempt after failing the first is:
p(2/1) = 0.15
Then the probability of failure of both attempts is:
P(2/1) = p(1 and 2) / p(1)
p(1 and 2) = P(1) * P(1/2)
p(1 and 2) = 0.5 * 0.15
and that is
p(1 and 2) = 0.075
