Answer:
Step-by-step explanation:
3*2x=6x, 3*5=10
So, 6x+10+4x = 5x+15
Add 6 and 4 which leaves you with 10x+10 = 5x+15
subtract 10 from 15 and that leaves you with 5 divided by 10x
x=2
Same for second equation
2*8x=16x and 2*3= 6
So 16x-6=16x+28
Add 6 to both sides so you get 34.
Now that 6 is gone you want x on one side so subtract 16x an it leaves you with 0. so X=34

Answer:
9.08% probability that in a day, there are 14 births. So it does not appear likely that on any given day, there will be exactly 14 births.
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given time interval.
In a recent year, a hospital had 4386 births.
An year has 365 days. So
Find the probability that in a day, there are 14 births. Does it appear likely that on any given day, there will be exactly 14 births?
This is P(X = 14).
9.08% probability that in a day, there are 14 births. So it does not appear likely that on any given day, there will be exactly 14 births.
