The statement is False. System services should only be turned off when the app is completely closed.
When an app moves out of the running state, it is simply transitioning from the foreground to the background. System services should not be turned off during this transition, as the app may still need to access these services while running in the background. Turning off system services during this transition will result in poor performance and may cause the app to crash. It is only when the app is completely closed that system services should be turned off. This ensures that the resources are freed up, and the app is no longer using any system services.

The range of your data in statistics is the range from the distribution's lowest value to its highest value. It serves as a typical indicator of unpredictability. Measurements of variability provide descriptive statistics for your data set's summary, together with measures of central tendency.
How useful is the range?If your distribution doesn't contain any extreme values, the range is typically a decent indicator of variability. You may learn more about the distribution's range by combining the range with measurements of central tendency.
When your data collection contains outliers, though, the range can be deceptive. You'll get a whole different range if the data has one extreme value.
A range example with an outlier
An outlier is used to substitute one value in your data collection.
Age 19 21 26 29 31 33 36 61
This time, while using the identical formula, the outcome is drastically different:
R = H – L
R = 61 – 19 = 42
Our current range is 42 years, barring an extreme.
The range in the previous example overstates the degree of data variability. The majority of the numbers are actually grouped around a distinct centre, despite the fact that we have a wide range.
Outliers can readily affect the range because there are only two numbers used. You cannot learn about the frequency distribution of values' shape from it on your own.

TECH- Your network uses a network address of 137. 65. 0. 0 with a subnet mask of 255. 255. 0. 0. How many ip addresses are available to assign to network hosts on this network?.
Answer:
The number of IP addresses available for assignment to network hosts in a network with a network address of 137.65.0.0 and a subnet mask of 255.255.0.0 is 65,534.
Explanation:
The subnet mask has 16 bits set to 1, meaning that the number of available IP addresses is equal to 2^(32-16) = 2^16 = 65,536. However, two of these IP addresses are reserved for network and broadcast addresses and cannot be assigned to network hosts, thus the actual number of available IP addresses for network hosts is 65,536 - 2 = 65,534.

How do I calculate 95% confidence interval?The overall capture rate when the approach is applied numerous times is the confidence level.
While the sample mean will vary from sample to sample, the method estimate's margin of error is used to obtain an interval depending on each sample.
C% of these intervals accurately represent the unidentified population mean. This means that, in C% of the cases, the real mean will be found within that range.
Margin of error sample mean to calculate the confidence interval.
By calculating a confidence range for that mean, one may estimate the population mean for a given variable.
In the event that numerous random samples were taken, the mean value for that variable would vary slightly between the samples.
Because of this, instead of giving a single figure when estimating population means, researchers offer a range of values (or an interval) that this mean is expected to fall within.
Adding and taking away the margin of error from the sample mean will yield this confidence interval. The upper and lower bounds of the confidence interval are determined by this outcome. According to the level of certainty or estimation precision needed, the confidence interval may be broader or narrower.

Expanding Your Web Design Skills As you progress in your studies of computer science, you will find that you will sometimes need to teach yourself how to use new platforms, apps, languages, and software. This is a crucial skill to develop so that you can keep your abilities ahead of the curve! In this lab, you will have a chance to learn a bit about two other markup languages: XML and DHTML. To begin, find an XML tutorial that you like. Some people prefer to learn by watching videos; others prefer a text-based explanation. Spend about 15 minutes exploring the XML tutorial. When you finish, create a list of 10 XML tags and explain their use. Next, find an article that explains what DHTML is. Write a paragraph that explains DHTML and includes an example of how it works.
Dynamic web pages commonly referred to as interactive and animated web pages are produced using DHTML.
What is DHTML?Dynamic Hypertext Markup Language is referred to as DHTML. It is a name for the methodical use of HTML, CSS, and different scripting languages like JavaScript, JScript, or VBScript rather than an independent markup language.
In order to create dynamic content, DHTML is built on the characteristics of HTML, JavaScript, CSS, and DOM (Document Object Model.

The internal parts of a computer are powered by a power supply unit (PSU), which transforms mains AC electricity into low-voltage, regulated DC power.
What is Power supply unit?Power supply with switched-mode technology are used in all modern personal computers. A manual switch is available on certain power supplies to choose the input voltage, while an automatic mains voltage adapter is available on others.
The majority of contemporary desktop personal computer power supply abide by the ATX specification, which covers form factor and voltage restrictions. A 5-volt standby (5VSB) power source is always provided by an ATX power supply while it is connected to the mains supply in order to power the computer's standby features and some peripherals. Using a motherboard signal, ATX power supply can be turned on and off.
When the DC voltages are within specs, they also send a signal to the motherboard, allowing the computer to safely power on and boot. At the beginning of 2022, version 3.0 of the ATX PSU standard was in effect.

consider the following method, which is intended to return the number of columns in the two-dimensional array arr for which the sum of the elements in the column is greater than the parameter val.
The correct answer is Think about the method count, which will iterate through every item in the two-dimensional (2D) String array things and return the overall number.
Although the values are still stored linearly in memory, a two-dimensional array is a type of data structure that consists of a set of cells arranged in a two-dimensional grid, much like a table with rows and columns .Here, the two dimensions' sizes are I and j, where I stands for the number of rows and j for the number of columns. A two-dimensional array named A with 10 rows and 20 columns is declared in C using the notation int A[10][20]. Objects can also be stored in a two-dimensional array, which is useful for programming diagrams that include a "grid" or "board." A grid of Cell objects that are stored in a two-dimensional array are shown in Example 13-11.
