Answer: D
Step-by-step explanation:
We can use ratios and the cross-multiply-divide to find this.
The ratio 21:5 is avaliable via the question. We then need to compare that to the ratio x:100, the 100 being the percent and the x being the number of airplane parts.
21/5 = x/100
We can then solve for x to find the number of airplane parts. First we multiply by 100 on both sides to get 2100/5 = x. Therefore x = 420 and there are 420 airplane parts.
Answer:
C. 570.20 ft²
Step-by-step explanation:
Surface
A = 2·pi·r^2 + 2·pi·r·h
A = 2·pi·5.5^2 + 2·pi·5.5·11 = 570.20 ft²
Answer:
0.9999985 = 99.99985% probability that in a day, there will be at least 1 birth.
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.
Assume that the mean number of births per day at this hospital is 13.4224.
This means that
Find the probability that in a day, there will be at least 1 birth.
This is:
In which
Then
0.9999985 = 99.99985% probability that in a day, there will be at least 1 birth.
