Answer:

There are additional security risks associated with using cloud computing over local data storage.

Explanation:

Cloud computing: The term "cloud computing" is described as a process through which an individual tends to access and store various programs and data over the internet rather than his or her computers' "hard drive". However, the term "cloud" here refers to a specific metaphor associated with the internet.

Types:

1. Software-as-a-service or SaaS.

2. Platform-as-a-service or PaaS.

3. Infrastructure-as-a-service or IaaS.

In the question above, the very first option is correct as all other options mentioned over here are incorrect because they aren't related to cloud computing.

Problem 2 - K-Best Values - 30 points Find the k-best (i.e. largest) values in a set of data. Assume you are given a sequence of

Answer:

See explaination

Explanation:

/**KBestCounter.java**/

import java.util.ArrayList;

import java.util.List;

import java.util.PriorityQueue;

public class KBestCounter<T extends Comparable<? super T>>

{

PriorityQueue heap;

int k;

public KBestCounter(int k)

{

heap = new PriorityQueue < Integer > ();

this.k=k;

}

//Inserts an element into heap.

//also takes O(log k) worst time to insert an element

//into a heap of size k.

public void count(T x)

{

//Always the heap has not more than k elements

if(heap.size()<k)

{

heap.add(x);

}

//if already has k elements, then compare the new element

//with the minimum element. if the new element is greater than the

//Minimum element, remove the minimum element and insert the new element

//otherwise, don't insert the new element.

else if ( (x.compareTo((T) heap.peek()) > 0 ) && heap.size()==k)

{

heap.remove();

heap.add(x);

}

//Returns a list of the k largest elements( in descending order)

public List kbest()

{

List al = new ArrayList();

int heapSize=heap.size();

//runs O(k)

for(int i=0;i<heapSize;i++)

{

al.add(0,heap.poll());

}

//Restoring the the priority queue.

//runs in O(k log k) time

for(int j=0;j<al.size();j++) //repeats k times

{

heap.add(al.get(j)); //takes O(log k) in worst case

}

return al;

}

Use the values in the range A7:A8 to extend the list of years to the range A9:A11. 3. Use AutoFill to fill the range A9:H11 with

jok3333 [9.3K]

Answer:

Question is incomplete and it needs a proper XL sheet image and more details. I have assumed and answered this question.

1. Use the values in the range A7:A8 to extend the list of years to the range A9:A11

Ans : Use Ctrl + select A7: A8 and drag till A9: A11 : This will extend the list

2. Use AutoFill to fill the range A9:H11 with the formatting from the range A7:H8.

Ans : Apply format immediately to the cells A9: H11 below with the help of Auto Fill Handle. Using Auto fill button we can able to a cell format to the cell bellow of active cell by just double clicking on the auto fill button.

3. In cell B8, create a formula without using a function that multiplies the value in cell B7 by the value in cell B6 and then adds the value in B7. Update the cell reference to cell B6, from a relative reference to a mixed reference by making an absolute reference to row

Ans : =($B7*$B6)+$B7

4. Copy the formula from cell B8 to the range B9:B11 and then copy the formulas from the range B8:B11 to the range C8:H11.

Ans:

1. Select the cell B8 that contains which has formula to be copied

2. Click inside the formula bar to activate it and select the entire formula by using mouse and keyboard.

3. Copy the selected formula and press Esc to deactivate the formula bar.

4. Select the cell B9 : B11 in which you want the copy of the formula to appear.

5. Most range names refer to absolute cell references. This means that when you copy a formula that uses a range name, the copied formula will use the same range name as the original.

6. Paste the formula by using references.

7. Repeat the steps of 1 to 6 for B8:B11 for range C8:H11.

5. Switch to the Cost Estimates worksheet. In cell A9, create a formula using the AVERAGE function that calculates the average of the values in the range A5:A7, then copy your formula to cell D9.

Ans : =AVERAGE(A5:A7) and Copy it to D9 using answer given in 4.

Find a 95% confidence interval for the mean failure pressure for this type of roof panel.The article "Wind-Uplift Capacity of Re

aliya0001 [1]

Answer:

The 95% confidence interval would be given by (2.351;3.525)

Explanation:

1) Previous concepts

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

$\bar X$ represent the sample mean

$\mu$ population mean (variable of interest)

s represent the sample standard deviation

n represent the sample size

2) Confidence interval

The confidence interval for the mean is given by the following formula:

$\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}$ (1)

In order to calculate the mean and the sample deviation we can use the following formulas:

$\bar X= \sum_{i=1}^n \frac{x_i}{n}$ (2)

$s=\sqrt{\frac{\sum_{i=1}^n (x_i-\bar X)}{n-1}}$ (3)

The mean calculated for this case is $\bar X=2.938$

The sample deviation calculated $s=0.472$

In order to calculate the critical value $t_{\alpha/2}$ we need to find first the degrees of freedom, given by:

$df=n-1=5-1=4$

Since the Confidence is 0.95 or 95%, the value of $\alpha=0.05$ and $\alpha/2 =0.025$ , and we can use excel, a calculator or a table to find the critical value. The excel command would be: "=-T.INV(0.025,4)".And we see that $t_{\alpha/2}=2.78$

Now we have everything in order to replace into formula (1):

$2.938-2.78\frac{0.472}{\sqrt{5}}=2.351$

$2.938+2.78\frac{0.472}{\sqrt{5}}=3.525$

So on this case the 95% confidence interval would be given by (2.351;3.525)
