Answer:
b) 0.9313
c) mean = 2.4
standard deviation= 1.3856
d) 0.5583
Step-by-step explanation:
Given:
p = 0.2
n = 12
a) X= number of applicants classified as deceptive.
Probability mass function of X will be:
b) Probability that the polygraph says at least 1 is deceptive:
= 1 - 0.0687
= 0.9313
c) The mean number among 12 truthful persons who will be classified as deceptive:
E(X) = n•p
= 12 * 0.2
= 24
Standard deviation:
= 1.3856
d) Probability that the number classified deceptive is less than the mean:
= 0.5583
The answer is 87,455
P(x) = P(0) * nˣ
P(x) - the final population after period x
P(0) - the initial population
n - the growth factor in decimal
x - period of time
x = 3 hours
P(3) = 25,143
P(0) = ?
n = 100- 34% = 66% = 0.66
P(x) = P(0) * nˣ
25,143 = P(0) * 0.66³
25,143 = P(0) * 0.287496
P(0) = 25,143 / 0.287496
P(0) ≈ 87,455
Answer: 77.31°
explanation: you’ll have to round it on your own it confuses me
Answer: D and E
Step-by-step explanation:
To find this answer we want to get x by itself in the equation.
6x + 4 < 22
6x < 18
x < 3
So according to this the value of x has to be less than 3.
You can check your answer by substituting the values in for x.
6(0) + 4 < 22
4 < 22 is True
6(2) + 4 < 22
16 < 22 is True
6(3) + 4 < 22
22 < 22 False!
