Answer:

a. double-cross

Explanation:

 Using the blockchain technology in the case of issuing concert tickets solves the problem with double-cross, which is when someone cheats another person who had trusted in them for some transaction. <em>A great asset with blockchain is the transparency with all the transactions because they are registered and cannot be erased or changed.</em>

Suppose there are 69 packets entering a queue at the same time. Each packet is of size 7 MiB. The link transmission rate is 1.7
svp [43]

Answer:

69.08265412 milliseconds

Explanation:

Lets first convert 7 MiB to bits

7*1024*1024*8=58720256 bits

Now convert bits to Gbits

58720256/10^{9}  =0.058720256 Gbits

Queuing Delay = Total size/transmission link rate

Queuing Delay= \frac{0.058720256}{1.7} =0.03454132706 seconds

Delay of packet number 3 = 0.03454132706*2=0.06908265412 seconds

or 0.06908265412= 69.08265412 milliseconds

You are troubleshooting a mobile device that will not pair with a Bluetooth headset. The device was functioning properly with th
bulgar [2K]

Answer:

B. Replace the Bluetooth headset with a new pair.

Explanation:

Since all other mobile devices, after receiving the "corporate-wide" OS update, aren't having issues with pairing with Bluetooth headsets, we can safely conclude that the OS update isn't the issue.

To find out if the Bluetooth headset is not the culprit, we can try to pair the mobile device with a different headset. If it pairs correctly, then we can conclude that the old Bluetooth headset might have a fault, or it might need to be disconnected/forget from the device and paired gain.
