Answer:
P(X > 5) = 0.1164 to 4 d.p.
The parameters are defined in the explanation.
Step-by-step explanation:
This is a binomial distribution problem
Binomial distribution function is represented by
P(X = x) = ⁿCₓ pˣ qⁿ⁻ˣ
n = total number of sample spaces = number of potential hires = 10
x = Number of successes required = number of potential hires that have prior call centre experience = more than half; that is, x > 5
p = probability of success = probability that any potential hire will have experience = (11/30) = 0.367
q = probability of failure = probability that any potential hire will NOT have experience = 1 - p = 1 - 0.367 = 0.633
P(X > 5) = P(X=6) + P(X=7) + P(X=8) + P(X=9) + P(X=10)
Inserting the parameters and computing the probabilities for each of those values of X,
P(X > 5) = 0.11641775484 = 0.1164 to 4 d.p.
Hope this Helps!!!
S(t) = S0·(1 + rate)t<span>S(t) = salary at year t

F(x)=2x^2-10
f(5)=2(5^2)-10
f(5)=2(25)-10
f(5)=50-10
f(5)=40
You answer is D hope this helps
0.3636... repeating = 4/11 .
I just recently learned how to find the fraction
that's equal to a repeating decimal.
-- Take the group of digits that repeats. (in this one, it's 36)
Write it on top of the fraction.
36 /
-- On the bottom of the fraction, write the same number of 9's .
For this one, it's 36 / 99 .
-- There's your fraction.
Simplify it if possible.
Divide top and bottom of this one by 9: 36/99 = 4/11 .
Is that cool or what !
