A point of sale, sometimes known as a POS, is a machine that handles retail customers' transactions. A POS includes a cash register.
The selling price is the sum that a company earns from the sale of a product. Markup is the sum that a company adds to the cost of goods to determine the selling price. Sales taxes are levied when goods or services are sold. Cash and revenue are the only two accounts that need to be used in a journal entry to record cash sales in the company's books. Both the cash balance and the revenue account on the company's balance sheet and income statement grow as a result of the entry.

What is service tag?A service tag is a specific group of IP addresses that are used by a particular Azure service. By using a service tag for Azure Backup, you can allow Azure Backup to connect to your VM without having to specify individual IP addresses. This minimizes the number of IP addresses that you need to allow, and also ensures that you will not accidentally block the IP addresses used by Azure Backup.
If you use any IP address, then it will allow all the incoming traffic which can be a security risk.
If you use the IP address of VM1 as the source, it will allow only the traffic from that specific IP which is not useful in this case.

actual
negative positive
predication negative 60 8
positive 22 10
The weakness of this model is that it has low recall value of 0.31, which means that it's not able to identify all the positive cases, particularly the ones that are actually having tumor.
The strength of this model is that it has a relatively high precision value of 0.56 which means that when it predicts a positive case, it's more likely to be correct.
What is the matrix about?The Confusion matrix is:
actual negative actual positive
predicted negative 60 8
predicted positive 22 10
Accuracy: (60 + 10) / 100 = 0.68
Precision: 10 / (10 + 8) = 0.56
Recall: 10 / (10 + 22) = 0.31
F1-Score: 2 * ((0.56 * 0.31) / (0.56 + 0.31)) = 0.39
The accuracy of the model is 68%, which means that the model correctly predicted the outcome in 68% of the test cases. However, this value alone doesn't give a complete picture of the model's performance.
Precision is the ratio of true positive predictions over all positive predictions, it's 0.56 which means that out of all patients that the model predicted as having a tumor, 56% of them actually had a tumor. F1-Score, which is the harmonic mean of precision and recall, is 0.39.
