Answer:
V is approximately 5572 cm^3
Step-by-step explanation:
A soccer ball is a sphere.
The volume of a sphere is
V = 4/3 pi r^3
V = 4/3 (3.14) (11)^3
= 4/3 * (3.14) 1331
5572.45333333
V is approximately 5572 cm^3
Answer: A & C
Step-by-step explanation:
You can also simplify the above by taking the -4 out of the radical
It becomes 2 x , which can be simplifed to C
Answer: 3
The answer is three, do you need me to show you how I solved it?
Answer:
0.2081 = 20.81% probability that at least one particle arrives in a particular one second period.
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.
Over a long period of time, an average of 14 particles per minute occurs. Assume the arrival of particles at the counter follows a Poisson distribution. Find the probability that at least one particle arrives in a particular one second period.
Each minute has 60 seconds, so
Either no particle arrives, or at least one does. The sum of the probabilities of these events is decimal 1. So
We want . So
In which
0.2081 = 20.81% probability that at least one particle arrives in a particular one second period.
