telo118 [61]

Answer:

DoS attack

Explanation:

A Denial of Service attack involves the sending of maliciously formatted data packets to a server. The packet can be larger than the allowed IP size such that when it arrives at the server, the server cannot identify the headers in the data packet for it to process and extract data. The server can either freeze or crash, denying allowed users access to its resources and making it unavailable.

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)

Assume the array of integers values has been created. Which condition must be used in the indicated area so the loop below will

scZoUnD [109]

Answer:

val > max

Explanation:

Assuming the values array is already created, inside the loop, we need to check if the val, a value in the values array, is greater than max. If it is greater than the max, that means it is our new max. Then we would set the max as the val. This way, if there is any value greater than max, it will be our max at the end of the loop.

Ishmael would like to capture a selected portion of his screen and then capture actions he preforms on that selected portion. Wh

kompoz [17]

Answer:

Use the Insert Screen .

Explanation:

Remember, on most computer keyboard you'll find a button named "Insert Screen' which functions as a screenshot too. Also, note that if Ishmael is using Windows operating system he should simply do the following;

1. open the window you want to screenshot

2. click the Screenshot button

But to select a part of the screen he would need to use Screen Clipping which would allow him select the part of the window that he wants. ( It screen will look opaque)

3. the pointer would change to a cross, then he should press and hold the left mouse button and drag to select the part of the screen that he wants to capture.
