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!!!
Answer:
x = 19
Step-by-step explanation:
The lower base angles in an isosceles trapezoid are congruent , then
5x - 20 = 2x + 37 ( subtract 2x from both sides )
3x - 20 = 37 ( add 20 to both sides )
3x = 57 ( divide both sides by 3 )
x = 19
Answer:
147
Step-by-step explanation:
The other two options would be more closed and since this angle is open, it is the larger one.
Answer:
is not proportional.
is proportional
2x + 3y = 7 is not proportional.
Step-by-step explanation:
.
This is an equation in the slope-intercept form and the y-intercept of the equation is (0,4).
Therefore, this equation does not pass through the origin.
So, the equation is not proportional.
This is also an equation in the slope-intercept form and the y-intercept of the equation is (0,0).
Therefore, this equation passes through the origin.
So, the equation is proportional.
2x + 3y = 7
⇒
This is also an equation in the slope-intercept form and the y-intercept of the equation is (
).
Therefore, this equation does not pass through the origin.
So, the equation is not proportional.

I think it's 108. But I'm not really good at math so...
