Answer:
Givens
First, we need to find the actual length of the car using Megan's ratio.
If 2 centimeters is equivalent to 1 actual meter of the car, 6 centimeters of drawing would be equal to
Therefore, the car is 4 meters long.
Now, using this information, we can find the length of the scale drawing of Ivan.
Therefore, Ivan's drawing is 8 centimeters long.
Answer:
0.1606 = 16.06% probability that the number of births in any given minute is exactly five.
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 interval.
In this question:
We only have the mean during an interval, and this is why we use the Poisson distribution.
The mean number of births per minute in a given country in a recent year was about 6.
This means that
Find the probability that the number of births in any given minute is exactly five.
This is P(X = 5). So
0.1606 = 16.06% probability that the number of births in any given minute is exactly five.
