Answer:
3x-x+2=4
Step-by-step explanation:
![42 \times \pi = 131.94 \\ 131.94 \times 3 = 395.84](https://tex.z-dn.net/?f=42%20%5Ctimes%20%5Cpi%20%3D%20131.94%20%5C%5C%20131.94%20%5Ctimes%203%20%3D%20395.84)
the ferris wheel spins 395.84 feet a minute
![395.84 \times 5 = about \: 1978feet](https://tex.z-dn.net/?f=395.84%20%5Ctimes%205%20%3D%20about%20%5C%3A%201978feet)
the answer is 1978 feet
17.54% is the probability that 5 messages are received in 1 hour.
The chance that X reflects the number of successes of a random variable in a Poisson distribution is provided by the following formula:
P(X = x) = (
×
) ÷ x!
In where x is the number of successes, e is the Euler number, and u is the mean in the specified time frame.
In this case, the average message rate is 5 messages per hour.
The probability of receiving 5 texts in one hour.
Determine the value of P for x = 5 and u = 6.
P(X = x) = (
×
) ÷ 5!
P(X = x) = 21.0560 ÷ 5!
P(X = x) = 0.1754
There is a 17.54% chance that 5 messages will be received in 1 hour.
