Use the function varimp() on the output of train() and save it to an object called imp:_____.

Orlov [11]

Use the function varimp() on the output of train() and save it to an object called imp object.

<h3>What is the classification that has More than Two Classes and the Caret Package</h3>

In the Classification that has More than Two Classes and the Caret Package section, one need to use the methods that can be able to adapt to higher forms or dimensions and through a lot of different machine learning algorithms.

Note that varImp is seen as a generic method for calculating variable .

Hence, Use the function varimp() on the output of train() and save it to an object called imp object.

Computer system with a 32-bit logical address and 4k-byte page size. assume that each entry of a page table consists of 4bytes.

Annette [7]

The number of bits in the physical address is 26 bits. The number of entries in a page table is $\mathbf{2^{20}}$ entries. The size of the page table in a one-level paging scheme is 4MB.

<h3>
What is paging in Operating System?</h3>

Paging is a storage method used in operating systems to recover activities as pages from secondary storage and place them in primary memory. The basic purpose of pagination is to separate each procedure into pages.

We are given the following parameters:

32-bit logical address
Page size = 4 KB = $\mathbf{2^{12} \ bytes }$
Size of each Page table entry = 4 bytes

Suppose the system supports physical memory size = 64 MB = $\mathbf{2^{26} \ bytes}$

Thus, the number of bits in the physical address is computed as:

= $\mathbf{log_2 \{Physical-memory-size\}}$

$=\mathbf{log_2(2^{26})}}$

= 26 bits

The number of entries in a page table = logical address space size/page size

The number of entries in a page table $\mathbf{= \dfrac{2^{32}}{2^{12}}}$

$\mathbf{=2^{20}}$ entries

In a one-level paging scheme, the size of the table is:

= entire no. of page entries × page table size

= $\mathbf{2^{20}\times 4 \ bytes}$

= 4 MB

b.

suppose that this system supports up to 2^30 bytes of physical memory.

The size of the page table will be the same as 4 MB due to the fact that the number of entries, as well as, the page table entry size is the same.

Since the size of the page table surpasses that of a single page. A page cannot include a whole page table. Therefore, the page table must be broken into parts to fit onto numerous pages, and an additional level of the page table is required to access this page table.

This is called the Multi-Level Paging system.

Therefore, we can conclude that the number of bits in the physical address is 26 bits, the number of entries in a page table is $\mathbf{2^{20}}$ entries, and the size of the page table in a one-level paging scheme is 4MB.

Assume that you have 22 slices of pizza and 7 friends that are going to share it (you've already eaten). There's been some argum

xz_007 [3.2K]

Answer:

In Python:

numberOfWholeSlices = int(22/7)

print(numberOfWholeSlices )

Explanation:

For each friend to get a whole number of slices, we need to make use of the int function to get the integer result when the number of slices is divided by the number of people.

So, the number of slice is: 22/7

In python, the expression when assigned to numberOfWholeSlices is:

numberOfWholeSlices = int(22/7)

Next, is to print the calculated number of slices

print(numberOfWholeSlices )
