Answer:
Early school starting times cause poor performance on tests, inattention in class, and drowsiness.
Explanation:
Carskadon study on early school starting time showed that it cause increased rate of rapid eye movement sleep in students and they doze off during lecture. Insufficient sleep lessens attentiveness levels in the class which affects students' potential to learn. The study showed that students do not perform well on tests. In addition to the difficulty in learning, there is an increased danger of accidents for those who drive to school due to dizziness.

Using python,
At one college, the tuition for a full-time student is $8,000 per semester.
It has been announced that the tuition will increase by 3% each year for the next five years.
Write a program with a loop that displays the projected semester tuition amount for the next five years as:
Answer:
Explanation:
We can use for-loop in python to calculate the tuition amount in the next 5 years. If the tuition is increasing 3% each year, in each loop we can multiply the amount by 1.03
tuition = 8000
for year in range(1,6):
tuition *= 1.03
print("The tuition amount after " + str(year) + " year(s) is $" + str(tuition))
In this exercise we have to use the knowledge of computational language in python to write the following code:
The code can be found in the attached image.
That way, to find it more easily we have the code like:
tuition = 8000
for year in range(1,6):
tuition *= 1.03
print("The tuition amount after " + str(year) + " year(s) is $" + str(tuition))

In Microsoft Excel, you have a large dataset that will print on several pages. You want to ensure that related records print on the same page with column and row labels visible and that confidential information is not printed. You should apply all of the following page setup options except which one to accomplish this?A. Set a print areaB. Print titlesC. Adjust the page breaksD. Change the print page order
Final answer:
To print related records on the same page with visible labels and exclude confidential data, set a print area, print titles, and adjust the page breaks. Do not change the print page order, as it does not help with these printing goals in Excel.
Explanation:
To ensure that related records print on the same page with column and row labels visible and that confidential information is not printed in Microsoft Excel, you would apply the following page setup options:
Set a print area to define the specific area of the worksheet that you want to print.Print titles to repeat specific rows or columns on every page, ensuring labels are visible across all printed pages.Adjust the page breaks to control where pages begin and end, which helps to keep related records together.The page setup option you should not apply is:
Change the print page order. This option changes the sequence in which pages are printed and does not assist in keeping related records together or ensuring that confidential information is omitted from the printout.By using the Page Layout tab, you can make adjustments like changing to landscape orientation or narrowing margins, which can help fit more data on each page. Using these settings effectively will help ensure your data prints out clearly and efficiently.

What in the LAN for a small office, some user devices connect to the LAN using a cable, while others connect using wireless technology (and no cable). which of the following is true regarding the use of ethernet in this LAN?
Answer:
The ethernet protocol IEEE 802.3 is only meant for cable networks.
Explanation:
In this scenario, there are two types of networks, namely;
LAN and WLAN.
A LAN (local area network) is a network within a small area like a building, i which its workstation are connected using cables. The cabled network instantly use a protocol called Ethernet also known as IEEE 802.3.
WLAN (wireless local area network) is a small area network just like the LAN, but the difference is that its workstation are connected wireless (without cable). wireless networks uses wifi or 802.11a/n/g to connect to the network.
So, the ethernet protocol represents the cabled network, Wifi represents the wireless network.
If you're looking to install Gigabit Ethernet, what cabling system would you use?
A. coaxial
B. thinnet
C. Cat-6
D. RG-59
Answer:
The correct answer to the following question will be option c. Cat-6.
Explanation:
Cat-6: A standard version of twisted pair cable for physical layer of networking and for Ethernet is, Cat-6 (Category 6) cable.
Cat-6 will be adaptable with the Category 5/5e and 3 standard of cables, and the standard specifies the performance of cable compared to 100 MHz up-to 250MHz for Cat 5/5e.So, if you are looking for the best cabling system to use while installing the Gigabit Ethernet, Category 6 will be the suitable one.True or false: The sensory regions of the brain are more vulnerable to shrinking with age than areas such as the prefrontal cortex.
Answer:
False
Explanation:
The "last-in, first-out hypothesis" is a widely accepted explanation for the effects of aging on the brain. This hypothesis entails that the areas of the brain that mature last are the first ones to age or thin out with passage of time. Therefore, the pre-frontal cortex, the cerebellum and hippocampus suffer the most thinning with age.

Which is true about the differences between a port replicator and a docking station?
Both have expansion ports
Neither have expansion ports
Only docking stations have expansion slots
Only port replicators have expansion slots
Answer:
The answer is 'D'- only port replicators have expansion slots.
Explanation:
A port replicator is a kind of attachment which allows multiple devices to be attached to the laptop through a simple USB. The devices can be a monitor, printer, large monitor, keyboard etc.
On the other hand a docking station allows portable computers to be connected to other hardware devices and get converted into a desktop system. Docking station can be plugged hot or cold. Cold docking is carried out when the system is shut down and hot docking occurs when the system is still running and the docking station is connected.

a. Backslash
b. Alt
c. Scroll
d. Tilde
To use an access key, you should hold down the b. 'Alt' key. This key is used for various shortcuts in software, such as inserting an equation with 'Alt' + '=' or a degree symbol with 'Alt+0176'.
To employ an access key, press and hold down the Alt key as you tap the access key. This is a common shortcut used in various applications to activate certain features quickly. For example, to insert an equation in certain software, you can use the shortcut "Alt" + "=" (press the "Alt" key and the "=" key simultaneously.
Additionally, if you want to insert a Degree Symbol in Word or Excel, the shortcut is holding down the Alt key and typing 0176, which is Alt+0176. Another interesting fact is that on German keyboards, to type the "a" symbol, the combination is "Alt Gr" key plus "Q" because the layout is different compared to American keyboards.

Bob is designing input screens for a re-designed system for the shipping and inventory department. For order forms, he puts Zip code first (as the database will take the zip code and look up the city and state); for receiving forms, he puts them in the order of city, then state, then zip code. His design choices will help experienced users be more productive.
Answer:
The correct answer to the following question is False.
Explanation:
Because he uses the wrong method for receiving form because by using the database commands he can get both order and receiving forms at a time but he firstly uses database for the order form then again use database for receiving form which is time-consuming. he can get both of the forms by using the Join by which he can merge tables to get convenient result.
Explains the strategic design choices Bob made for input screens based on zip code, city, state, and order of information for enhanced productivity in the shipping and inventory department.
Zip code plays a crucial role in database management, allowing for efficient retrieval of location-based information. In Bob's design choices for input screens, placing zip code first on order forms streamlines the process by utilizing the database to look up city and state details.
For receiving forms, sorting information in the order of city, state, then zip code optimizes the workflow for local delivery. This tailored approach enhances productivity for experienced users in the shipping and inventory department.
Overall, Bob's strategic positioning of data fields aligns with best practices in user experience design, demonstrating a keen understanding of information organization based on context and workflow efficiency.
