Answer:
a) 60%
Step-by-step explanation:
This problem can be solved through binomial probability
Let's say probability of success is the probability of absent
p = 5% = 0.05
Probability of failure
q = 1-p = 0.95
The number of trial in this case is the number of employees randomly selected
n = 10
Since we are looking for 0 absent employee, we are looking for the probability that the success is nil (i.e 0)
x = 0
Binomial therorem
B(n,x,p) = B(10,0,0.05)
= C(10,0) * p^x * q^(n-x)
= 1 * (0.05^0) * (0.95^10)
= 1 * 1 * 0.95^10
= 0.59873693923
= 0.6 or 60%
Answer:
4 days
Step-by-step explanation:
We need to use the probability functions of each of the intervals to know the Probability number and then use it in the expected value.
P(x>3 cargo ships) = 1-P(x<=3)
P(x>3) = 1-P(x<=3)
P(x>3) = 1-[P(x=0)+P(x=1)+P(x=2)+P(x=3)]
P(x>3) = 1- [0.1353(1+2+2+1.33)]
P(x>3) = 1-0.856
P(x>3) = 0.1431
Als n=30, expected number is
E(x) =30*P(x>3)
E(x) = 30*0.1431
E(x) = 4.293
I expect 4.293 or 4 days per month the block being unable to hanlde all arriving ships
The answer is the last one (-20)
25%, 0.3, 2/5
25% = .25
2/5 = .4
Answer:
dont even stress i gotchu
It's 50*, 46* and 84*.
Ratio of the second problem is 1:1 they both have a slope of 1 (which is probably why all three points are on the same line)
Step-by-step explanation:
Since we know that the straight/flat angle would equal 180* we will set the total of all those angles to 180*
We will add them up to find x. Once we find x we can find the value of each angle.
6x-10 + 4x + 6 + 7x + 14 = 180
We will combine like terms and solve for x.
17x+10 = 180
17x = 170
x = 10.
Since we have x = 10, we will plug it into x of each angle to get the value of each angle.
6(10) -10 = 60-10 which equals 50*
4(10) + 6 = 40+6 which equals 46*
7(10) + 14 = 70 + 14 which equals 84*.
