Answer:
1/2
Step-by-step explanation:
1/3 divided by 2/3
1/2
27000 is halfway because the difference between them is 500. 500 divided by 2 is 250. 26750plus 250 is 27000
Answer:
![{2}^{7}](https://tex.z-dn.net/?f=%20%7B2%7D%5E%7B7%7D%20)
Step-by-step explanation:
![{2}^{7} = 128](https://tex.z-dn.net/?f=%20%7B2%7D%5E%7B7%7D%20%20%3D%20128)
![{7}^{2} = 49](https://tex.z-dn.net/?f=%20%7B7%7D%5E%7B2%7D%20%20%3D%2049)
So,
![128 > 49 \\ {2}^{7} \: \: \: \: > {7}^{2}](https://tex.z-dn.net/?f=128%20%3E%2049%20%5C%5C%20%20%7B2%7D%5E%7B7%7D%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%5C%3A%20%20%20%20%3E%20%20%7B7%7D%5E%7B2%7D%20)
Therefore 2^7 is greater

Answer:
0.395 or 39.5% probability that the first metal-carrying person missed (not detected) is a
Step-by-step explanation:
The easiest way to solve this problem is to determine the probability of all 50 of the first 50 metal-carrying people scanned being caught by the metal detector (P(C)). Then, the probability that the first metal-carrying person missed is within the first 50 (P(M)) is 100% minus the probability of all 50 being caught:
![P(C) = 0.99^{50}\\P(C) = 0.605](https://tex.z-dn.net/?f=P%28C%29%20%3D%200.99%5E%7B50%7D%5C%5CP%28C%29%20%3D%200.605)
![P(M) = 1- P(C) \\P(M)= 1- 0.605\\P(M)=0.395](https://tex.z-dn.net/?f=P%28M%29%20%3D%201-%20P%28C%29%20%5C%5CP%28M%29%3D%201-%200.605%5C%5CP%28M%29%3D0.395)
There is a 0.395 or 39.5% probability that the first metal-carrying person missed (not detected) is among the first 50 metal-carrying people scanned.
