Answer:
9.48% probability that exactly 12 parts are produced in one day
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.
The number of defective parts produced by a process in one day has a Poisson distribution with a mean of 10.
This means that
What is the probability that exactly 12 parts are produced in one day
This is P(X = 12).
9.48% probability that exactly 12 parts are produced in one day
Radius = Diameter ÷ 2 = 10 ÷ 2 = 5 cm
Volume = 4/3 πr³ = 4/3 π(5)³ = 524 cm³
Answer: 524 cm³ of water is needed to fill the balloon.
Answer:b
Step-by-step explanation: Cause I took the test
The number of tickets to sell at the door is 48 tickets.
<u>Step-by-step explanation</u>:
- Cost of play at the door = $5
- Cost of play in advance = $4
- The theater club wants to raise at least $400 from the play.
- Number of tickets sold in advance = 40 tickets.
Let 'x' be the number of tickets need to sell at the door.
5x + 4(40) = 400
5x + 160 = 400
5x = 240
x = 240/5
x = 48 tickets
The number of tickets to sell at the door is 48 tickets.
