The quickest way to change a word is to double
click it.
Select the correct answer
O True
False
Answer:
I don't think that the fastest way to change a word is to double click it. Even though it highlights it super fast, then you just press backspace once, it doesn't compare to the one where you press the "ctrl" and "backspace" key at the same time, and it makes the whole entire word disappear in the blink of an eye. But, I am not sure if anybody really knows about this trick. So, it is 50/50.

Explanation:
Suppose that you have a computer with a memory unit of 24 bits per word. In this
computer, the assembly program’s instruction set consists of 198 different operations.
All instructions have an operation code part (opcode) and an address part (allowing for only one address). Each instruction is stored in one word of memory.
1. How many bits are needed for the opcode?
2. How many bits are left for the address part of the instruction?
3. How many additional instructions could be added to this instruction set without
exceeding the assigned number of bits? Discuss and show your calculations.
4. What is the largest unsigned binary number that the address can hold?
Answer:
a ) The amount of bits required for the opcode
8 bits
2^8= 256
256>198
We get the next lower number, which is 2^7 = 128 bits, because it is greater than 198. As a result, the operation code necessitates 8 bits.
b) The number of bits reserved for the instruction's address.
16 bits
24-8 = 16
c)
65536
2^16 = 65536
Maximum number = 65535
2^15 = 32768-1
= 32767

I am assuming this is in python, so I will use comments to explain each step
l=int(input('What is the length of the rectangle')
w=int(input('What is the width of the rectangle')
#here use whatever graphics code required to draw the rectangle
#will probably be similar to rect=Rectangle(l,w)

Use the knowledge in computational language in python program checks to see if the input is output.
How to define input in Python?In Python, we do this using the input() function, which is literally 'input' in English. The input() function receives as a parameter a string that will be shown as an aid to the user, usually informing him what kind of data the program is expecting to receive.
So in an easier way we have that the code is:
def isNumber(x):
if type(x) == int:
return True
else:
return False
input1 = 122
input2 = '122'
if isNumber(input1):
print("Integer")
else:
print("String")
if isNumber(input2):
print("Integer")
else:
print("String")

What rules should we have about cell phone
the classroom/school?.
THIS IS AN 5 PARAGRAPH ESSAY HELP ME
Introduction: There are many rules schools should follow when it comes to cell phone use during school hours. Technology can be very distracting and durning school is when kids need to pay attention. Most people see cell phone rules un fair or bad, however it's not like that. The school just wants what's best for the students and so they can learn, which will ultimately help them on later in life.
Body paragraphs (wont write the rest of the paragraphs but heres some ideas) Only using the phone when needed like if it's an emergency, phones have to stay on silent to not disrupt others, during free period you can choose whether to be on your phone
then you write your conclusion based on what you wrote
Most of the Info you would need:
-If we don't allow cellphones many school issues would be solved.
-There is a mistake if they use cellphone, but its a great mistake if they misuse.
- Phones in classes just defeat the point of going to school- for learning.
- There are benefits, yes, but there is no doubt that the privilege will be abused.
-Cell phones are only good for distracting the students from the education that they are at school to obtain.
- we think it is one of the best ways to get distracted during class to use your cellphone.
-Cell phones create massive and on going classroom management issues for teachers.
-There is no need for allowing students to use mobile phones in schools. Ultimately they are not using mobiles for the calling purpose. Thus it is a perfect no from our side.

Thirty percent of a magazine's subscribers are female. A random sample of 50 subscribers Answer the following questions using Excel: (using standart devision of 0.0648)
a. What is the probability that the proportion of females from this sample is at most 0.25
b. What is the probability that the proportion of females from this sample is between 0.22 and 0.28
c. What is the probability that the proportion of females from this sample is within 0.03 of the population proportion?
Based on the mean of the subscribers, the sample size, and the standard deviation, the probability of females being at most 0.25 is 0.2202.
The probability that they are between 0.22 and 0.28 is 0.2703.
The probability that they are within 0.03 of the population proportion is 0.3566.
What is the probability that they are at most 0.25?Using Excel, we shall assume that the distribution is normally distributed.
We can therefore use the NORM.DIST function:
=NORM.DIST(0.25,0.3,0.0648,TRUE)
= 0.2202
What is the probability that they are between 0.22 and 0.28?=NORM.DIST(0.28,0.3,0.0648,TRUE) - NORM.DIST(0.22,0.3,0.0648,TRUE)
= 0.2703
What is the probability that they are within 0.03 of the population proportion?X high = 0.30 + 0.03
= 0.33
X low = 0.30 - 0.03
= 0.27
= NORM.DIST(0.33,0.3,0.0648,TRUE) - NORM.DIST(0.27,0.3,0.0648,TRUE)
= 0.3566.
