Consider the following classes of schedules: conflict-serializable(a), recoverable(b), and avoids-cascading-aborts (c). For each of the following schedules, state which of the preceding classes it belongs to. If you cannot decide whether a schedule belongs in a certain class based on the listed actions, explain briefly.
The actions are listed in the order they are scheduled and prefixed with the transaction name. If a commit or abort is not shown, the schedule is incomplete; assume that abort or commit must follow all the listed actions.
For simplicity, you should answer the questions in the following way. For example, you say a schedule is conflict-serializable(a), but not recoverable(b), and cannot decide avoids-cascading-aborts (c),

When writing about facts, opinions, or regular occurrences, we employ the present tense. To write about upcoming events, we utilize the future tense. Each of those tenses has additional characteristics, but we won't cover them in this session.

It's crucial to maintain the same tense throughout a writing endeavor after you've decided on one. To communicate yourself clearly, you may need to switch up the tense from time to time.

In Excel, total sales can be calculated for an array or range of data using an Array Formula: SUM(COUNTIFS(B3:B6,"Picasso"),COUNTIF(E3:E8,"Picasso")

An array is a collection of identical data elements that are kept in memory at adjacent locations. It is the simplest data structure because all that is required to access each data element is its index number. For instance, there is no need to define distinct variables for each subject if we want to store a student's marks across five subjects. Instead, we can define an array that stores the data elements in memory at locations that are adjacent to one another.

Marks[0] denote the marks scored in the first subject, marks[1] the marks scored in the second subject, and so on. The marks scored by a student in each of the five subjects are defined by the array marks[5,] where each subject's marks are located at a specific location in the array.

(a) The total capacity of the hard disk drive is 10 surfaces * 10240 tracks/surface * 512 sectors/track * 4 KB/sector = 204800 MB = 200 GB.

(b) The physical address of the sector with LBA 2312349 is calculated as: surface = LBA/(trackssectors) = 2312349/(10240512) = 4; track = (LBA%(trackssectors))/sectors = (2312349%(10240512))/512 = 2512; sector = LBA%sectors = 2312349%512 = 85.

So, it's (4, 2512, 85).

(c) The longest time to read an arbitrary sector is from the outermost track to the innermost track (10240 tracks) at 1280 track/ms speed, plus one full rotation at 5400 RPM: (10240/1280) ms + (60/5400) s = 8 ms + 11.11 ms = 19.11 ms.

3rd and 4th sentence

1st question just take a hint

The code is given below.

Python is a high-level, interpreted programming language that was first released in 1991. It is named after the Monty Python comedy group and was created by Guido van Rossum. Python is known for its readability, simplicity, and ease of use. It supports multiple programming paradigms, including procedural, object-oriented, and functional programming.

Here is the sample Python code to accomplish the task:

userNum1 = int(input("Enter userNum1: "))

if userNum1 < 0:

   print("userNum1 is negative.")

userNum2 = int(input("Enter userNum2: "))

if userNum2 > 15:

   userNum2 = 2

else:

   print("userNum2 is less than or equal to 15.")

This code prompts the user to enter two integer values userNum1 and userNum2. Then, it checks if userNum1 is less than 0, and if it is, it prints "userNum1 is negative.". The code also checks if userNum2 is greater than 15, and if it is, it assigns userNum2 to 2. Otherwise, it prints "userNum2 is less than or equal to 15.".

I can provide you with general instructions on how to create a line chart in Microsoft Excel based on the data you have mentioned.

To create a line chart of the data for the total spent on advertising each month from January through June in Microsoft Excel, you can follow these steps:

Open Microsoft Excel and open the AdvertisingCosts worksheet.

Select the data range for the months and total spent on advertising from January through June.

Click on the "Insert" tab on the Excel ribbon.

Click on the "Line" chart type under the "Charts" section.

Select the chart subtype that you prefer from the drop-down menu. For example, you can choose a simple line chart or a chart with markers for each data point.

Your chart will be created, but it may need some adjustments to make it look better. For example, you may want to add a chart title, axis titles, and legend to the chart.

Click on the chart to activate the "Chart Tools" tab on the Excel ribbon.

Use the options on this tab to customize your chart as needed. For example, you can add a chart title by clicking on the "Chart Title" button, or you can change the axis titles by clicking on the "Axis Titles" button.

Once you have completed these steps, you should have a line chart of the data for the total spent on advertising each month from January through June. The primary horizontal axis should be the months of the year, and the Vertical (value) Axis should be the total spent on advertising each month.
