4 or more apples could be green because if there are 3 or less red then there must be 4-7 green
Answer:
25
2:3
Step-by-step explanation:
2/5 were sold out
5/5 - 2/5 = 3/5
That means 3/5 were not sold out
p = performances
there were 15 that were not sold out
3/5 * p = 15
Multiply each side by 5/3
5/3 *3/5 p = 15*5/3
p = 25
There were 25 performances
sold out to not sold out
2/5 : 3/5
Multiply by 5
2: 3
Answer:
The probability that more than 30 minutes will elapse before the next fraudulent corporate tax return is discovered=0.1353
Step-by-step explanation:
We are given that
![\beta=15](https://tex.z-dn.net/?f=%5Cbeta%3D15)
We have to find the probability that more that 30 minutes will elapse before the next fraudulent corporate tax return is discovered.
Using exponential distribution
![P(X> x)=e^{-\frac{x}{\beta}}](https://tex.z-dn.net/?f=P%28X%3E%20x%29%3De%5E%7B-%5Cfrac%7Bx%7D%7B%5Cbeta%7D%7D)
The probability that more than 30 minutes will elapse before the next fraudulent corporate tax return is discovered
![=P(x>30)=e^{-\frac{30}{15}}](https://tex.z-dn.net/?f=%3DP%28x%3E30%29%3De%5E%7B-%5Cfrac%7B30%7D%7B15%7D%7D)
The probability that more than 30 minutes will elapse before the next fraudulent corporate tax return is discovered
![P(x>30)=0.1353](https://tex.z-dn.net/?f=P%28x%3E30%29%3D0.1353)
Hence, the probability that more than 30 minutes will elapse before the next fraudulent corporate tax return is discovered=0.1353
