Y/ 100 is the fraction that you should get
5/27 in simplest form because 20 flights out of 108 are linger than three hours, 20/108. Simplify 20/108 to get 5/27!
Answer:
a) P(X = 0) = 0.5997
b) P(X = 9) = 0.0016
c) P(X = 8) = 0.0047
d) P(X = 5) = 0.4018
Step-by-step explanation:
These following problem are examples of the binomial probability distribution.
Binomial probability
Th binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinatios of x objects from a set of n elements, given by the following formula.

And
is the probability of X happening.
(a) for n = 4 and π = 0.12, what is P(X = 0)?

(b) for n = 10 and π = 0.40, what is P(X = 9)?

(c) for n = 10 and π = 0.50, what is P(X = 8)?

(d) for n = 6 and π = 0.83, what is P(X = 5)?

Answer:
-6
Step-by-step explanation:
given
x³ = -216
x = (-216)^⅓
factorize
x = [(-6)×(-6)×(-6)]^⅓
x = -6
Answer: $1117.42
Step-by-step explanation:
Given: The amount predicted by Economist =$1180
Let x be the amount spent by Americans on Summer vacation in 2014.
Therefore, According to the question, we have
5.6% of x+x=1180

Hence, the amount spent by Americans on Summer vacation in 2014 = $1117.42
