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.

Answer:
m∠ACE = 40°
Step-by-step explanation:
Consider the below figure attached with this question.
Given information: arc BD = 25°, minor arc AB = 115°, and minor arc DE = 115°.
We need to find the measure of ∠ACE.
minor arc AB + minor arc BD + minor arc DE + minor arc AE = 360°
115° + 25° + 115° + minor arc AE = 360°
255° + minor arc AE = 360°
minor arc AE = 360° - 255°
minor arc AE = 105°
The measure of minor arc AE is 105°.
Using Intersecting secants outside the circle theorem
Angle between two secants =
(Major arc - Minor arc)
![\angle ACE=\frac{1}{2}[Arc(AE)-Arc(BD)]](https://tex.z-dn.net/?f=%5Cangle%20ACE%3D%5Cfrac%7B1%7D%7B2%7D%5BArc%28AE%29-Arc%28BD%29%5D)
![\angle ACE=\frac{1}{2}[105-25]](https://tex.z-dn.net/?f=%5Cangle%20ACE%3D%5Cfrac%7B1%7D%7B2%7D%5B105-25%5D)
![\angle ACE=\frac{1}{2}[80]](https://tex.z-dn.net/?f=%5Cangle%20ACE%3D%5Cfrac%7B1%7D%7B2%7D%5B80%5D)

Therefore, the measure of ∠ACE is 40°.
