Define Mn, k] to be the minimum possible cost over all partitions of (81,...,8n) into k ranges. Consider the input (100, 200, 300, 400, 500, 600, 700) with k = 3. What is M(7,3)?
The minimum possible cost over all partitions of (81, 82, ..., 800) into three ranges is 48. Hence, M(7,3) = 48.
Explanation:
To find M(7,3), we need to partition the sequence (81, 82, ..., 800) into three ranges. Let's first consider a general strategy for finding Mn,k].
We can start by assuming that the first range includes the first m terms for some m between 1 and n, and the second range includes the next l terms for some l between 1 and n-m, and the third range includes the remaining n-m-l terms. Then the cost of this partition is the sum of the costs of the three ranges, where the cost of a range is the difference between the maximum and minimum terms in that range. In other words, the cost of the partition is:
( max(81, 82, ..., 8m) - min(81, 82, ..., 8m) ) + ( max(8m+1, 8m+2, ..., 8m+l) - min(8m+1, 8m+2, ..., 8m+l) ) + ( max(8m+l+1, 8m+l+2, ..., 800) - min(8m+l+1, 8m+l+2, ..., 800) )
We want to find the partition that minimizes this cost. To do so, we can use dynamic programming. We can define a table dp[i][j] to be the minimum possible cost of partitioning the first i terms into j ranges. Then we can fill in this table using the recurrence:
dp[i][j] = min( dp[m][j-1] + max(81, 82, ..., 8i) - min(81, 82, ..., 8m) )
where the minimum is taken over all possible values of m between j-1 and i-1. The base cases are dp[i][1] = max(81, 82, ..., 8i) - min(81, 82, ..., 8i) (since there is only one range) and dp[j][i] = 0 (since there are j ranges and only j-1 partitions, so one range must be empty).
Once we have filled in the table dp, we can find Mn,k] by looking at dp[n][k].
Now let's apply this to the specific input (100, 200, 300, 400, 500, 600, 700) with k = 3. We want to find M(7,3), which is the minimum possible cost over all partitions of (81, 82, ..., 800) into three ranges. Using the dynamic programming approach described above, we can fill in the following table:
| i\j | 1 | 2 | 3 |
| --- | - | - | - |
| 1 | 0 | 0 | 0 |
| 2 | 8 | 0 | 0 |
| 3 | 16| 16| 0 |
| 4 | 24| 24| 24|
| 5 | 32| 32| 32|
| 6 | 40| 40| 40|
| 7 | 48| 48| 48|
The entry dp[7][3] is 48, so M(7,3) = 48. This means that the minimum possible cost over all partitions of (81, 82, ..., 800) into three ranges is 48. One such partition that achieves this cost is:
[81, 82, ..., 233], [234, 235, ..., 466], [467, 468, ..., 800]
In this partition, the cost of the first range is 233-81 = 152, the cost of the second range is 466-234 = 232, and the cost of the third range is 800-467 = 333, for a total cost of 152+232+333 = 717.

a join based upon a column from each table containing equivalent data is known as a(n) ____.
A join based upon a column from each table containing equivalent data is known as an "equijoin".
In database management systems, an equijoin is a common technique used to combine data from two or more tables in a relational database. This type of join specifically occurs when the selected columns from each table have matching values. To perform an equijoin, a query is written using the SQL (Structured Query Language) SELECT statement, which is used to retrieve the desired data. The JOIN clause is then used to specify the tables that need to be combined, and the ON clause defines the condition for the join, typically comparing the values in the specified columns.
Equijoins are essential for consolidating data from multiple tables, allowing you to gather relevant information from different sources and analyze it more efficiently. They are particularly useful when you need to retrieve related data that is stored across several tables, such as retrieving customer details and their order history from separate tables.
In summary, an equijoin is a crucial operation in relational databases that helps combine data from multiple tables based on matching values in the selected columns. It allows for efficient data retrieval and analysis, ensuring that the required information is easily accessible.

a memory's addressibility is 64 bits. what does that tell you about the size of the mar and mdr?
A memory's addressability refers to the number of bits used to represent the memory address. In this case, with a 64-bit addressability, it indicates that the Memory Address Register (MAR) and the Memory Data Register (MDR) must be compatible with this addressing system.
The MAR stores the memory address from which data will be fetched or to which data will be stored. With 64-bit addressability, the MAR will be 64 bits wide to accommodate the full range of possible memory addresses. This allows the system to access a vast amount of memory locations, specifically 2⁶⁴ unique addresses.
The MDR holds the data that is being read from or written to the memory. While the size of the MDR is not directly determined by the addressability, it is usually designed to match the data bus width of the system. For example, in a 64-bit system, the MDR is likely to be 64 bits wide as well, ensuring efficient data transfer between the memory and the CPU.
In summary, 64-bit addressability implies a 64-bit wide MAR to store memory addresses, allowing access to a large number of memory locations. The MDR's size may also be 64 bits wide, depending on the system's data bus width, facilitating efficient data communication with the memory.

The machine that reads the scantron sheet uses optical mark recognition technology to detect which bubbles have been filled in and then compares those answers to the correct ones to determine a score. This technology has been widely used for many years in academic settings and is still in use today, despite advancements in digital testing methods.
Scantron sheets are used for a wide range of assessments, including standardized tests, quizzes, and surveys. They offer an efficient and accurate way to grade tests with many multiple-choice questions and can help save time for teachers and professors who would otherwise have to grade the tests by hand. Overall, the scantron is an important input device that has helped simplify the grading process for millions of tests over the years.

nested tags automatically adopt the properties of tags that are higher in the tag structure. true or false
True. In HTML, nested tags inherit the properties of their parent tags. This means that any styles or attributes applied to a parent tag will also apply to its child tags, unless those child tags have their own styles or attributes that override the parent's.
For example, if a <div> tag has a font size of 16px and contains a <p> tag, the text within the <p> tag will inherit the font size of 16px, unless a different font size is specified for the <p> tag itself. This can be useful for creating consistent styles across a website or web page.
In addition, nested tags can also inherit the behaviors and attributes of other tags higher up in the structure, such as the <body> tag or the global <html> tag. This is because HTML uses a hierarchical structure to organize content and apply styles and attributes, and nested tags follow this structure by default.

which of the following can be represented by a single binary digit? select two answers. responses the position of the minute hand of a clock the position of the minute hand of a clock the remainder when dividing a whole number by 2 the remainder when dividing a whole number by 2 the value of a boolean variable the value of a boolean variable the volume of a car radio
A single binary digit can represent either 0 or 1, which works well for these two options as they have only two possible values.
In binary notation, each digit can only have two possible values, 0 or 1. Therefore, any variable or quantity that can only have two possible values can be represented by a single binary digit.
For example, when we divide a whole number by 2, the remainder can only be either 0 or 1. Thus, the remainder can be represented by a single binary digit, where 0 indicates no remainder and 1 indicates a remainder of 1.
Similarly, a boolean variable can only have two possible values: true or false. Therefore, the value of a boolean variable can also be represented by a single binary digit, where 0 indicates false and 1 indicates true.
On the other hand, the position of the minute hand of a clock and the volume of a car radio are continuous variables that can have infinite values within a certain range. Therefore, they cannot be represented by a single binary digit.
Based on your question, two options can be represented by a single binary digit:
1. The remainder when dividing a whole number by 2
2. The value of a boolean variable
