Answer:
(A) The CPU time for J1 is =2 ms other time is =18 ms, for J2 CPU time =6 ms other time = 24 ms, for J3 CPU time = 3 ms and other time = 12 ms (B) The CPU Utilization for uni-programming is 0.203 or 20.3% (C) For Multi-programming, when a program is not free and busy with an operation, the CPU is allocated to other programs.
Explanation:
Solution
Given that:
A(1)Job J1 = CPU time = 2ms
Other time =18 ms
Total time = 20 ms
(2)Job J2 = CPU time 6ms
Other time = 24 ms
Total time = 30 ms
(3)Job J3 = CPU time = 3ms
Other time =12ms
Total time = 15 ms
(B) For the CPU Utilization for uni-programming, we have the following as follows:
CPU utilization =The total time of CPU/The total real time
Thus,
=(2 +6+3) / (18+24+12)
= 11/54
=0.203 or 20.3%
(C) For the CPU utilization for multi-programming, when a program is not available that is busy in an operation, such as the input and output the CPU can be allocated or designated to other programs

Draw a flow chart that accepts mass and volume as input from the user. The flow chart should compute and display the density of the liquid.( Note: density = mass/volume ).
Answer:
See attachment for flowchart
Explanation:
The flowchart is represented by the following algorithm:
1. Start
2. Input Mass
3. Input Volume
4 Density = Mass/Volume
5. Print Density
6. Stop
The flowchart is explained by the algorithm above.
It starts by accepting input for Mass
Then it accepts input for Volume
Step 4 of the flowchart/algorithm calculated the Density using the following formula: Density = Mass/Volume
Step 5 prints the calculated Density
The flowchart stops execution afterwards

Explanation:
In the given python code, three methods "leap_year, number_of_days, and days_left " is declared, in which we calculate all the values that can be described as follows:
In the leap_year method, it accepts the year variable, which calculates the year is the leap year and returns its value that is 1. In the next method number_of_days, it is declared that accepts the "year and month" variable as the parameter and calculates and returns its value. In the last days_left method, it calculates the left days and returns its value, and outside the method, two dictionary variable days_31 and days_30 is declared, which assign a value and used use three input variable day, month, and year variable to accepts user input value. In the next step, a choice variable is declared, that input values and calls and print its value accordingly.The calendar program illustrates the use of conditional statements
In programming, conditional statements are used to make decisions.
The calendar program in Python where comments are used to explain each line is as follows:
#This defines the function that calculates the days in a month
def daysMonth(month,year):
#This checks for leap year (i.e. February), and returns the number of days
if month==2:
if ((year%4==0) and (year%100!=0)) or (year%400==0):
return 29
return 28
#This checks and returns the number of days in the other months
if month in [1,3,5,7,8,10,12]:
return 31
return 30
#This defines the function that calculates the days remaining in a year
def countDays(day,month,year):
#This calculates the days remaining in the current month
daysLeft = daysMonth(month,year)-day
month += 1
#The following loop determines the days left in the year
while month<=12:
daysLeft += daysMonth(month,year)
month += 1
#The returns the days left in the year
return daysLeft
#This gets the day as input
day = int(input('Day: '))
#This gets the month as input
month = int(input('Month: '))
#This gets the year as input
year = int(input('Year: '))
#This gets the choice
choice = int(input("1 - Days in the month\n2 - Days left in the year\nChoice: "))
#If the choice is 1, this prints the days in the month
if choice==1:
print("There are",daysMonth(month,year),"days in the month")
#If the choice is 2, this prints the days left in the year
elif choice==2:
print("There are",countDays(day,month,year),"left in the year")

In terms of twitch skills vs thought skills, Tetris: (1 point)
emphasizes twitch skills
emphasizes thought skills
emphasizes both twitch and thought skills
uses neither type of skill
The correct answer is C. Emphasizes both twitch and thought skills
Explanation:
In games, twitch skills refer to the player's ability to respond in a short time or react to a certain stimulus. On the other hand, thought skills are complex skills that require players to create strategies or analyzing before taking any action in the game.
In the case of Tetris, which requires players to complete lines by using pieces with different shapes both twitch and thinking skills are involved because to complete the line correctly the players needs to analyze the shape and where this should be placed before pressing any buttons (though skills), but at the same time, the player needs to reach in a short time (twitch skills) for example, by rotating each piece in a short time to complete the line.
Why is the number 0 important in computing?
In which part of a presentation should you provide background information, ask a thoughtful question, or offer an interesting
fact?
opening
outline
body
closing
The correct answer is A. Opening
Explanation:
In a presentation or the text, the opening is the first section that should allow the audience to understand what is the topic and focus. This is achieved through a hook that can include an interesting fact or a rhetorical question (a question that makes the audience think) because these two elements grab the attention of the audience. Additionally, after the hook, it is common to provide background information about the topic of the presentation, and finally, the speaker will state the main point or thesis statement. This occurs before the body of the presentation, which is the main section, and the closing, which is the last section. Thus, elements such as background information or an interesting fact are part of the opening.

If involved in a boating accident causing serious bodily injury or death while boating under the influence, the operator has committed a _____. felony misdemeanor non-criminal offense liability
Answer:
felony
Explanation:
It is an offence on the part of a boat operator who is under the control of alcohol while boating, as such could result in property damage, serious bodily injury or death. Where such leads to bodily injury or deaths, the operator could be convicted for felony while misdemeanor applies to property damage.
There have been a reoccurring boating incidence in the country especially in the state of Florida, which has the highest number of boating fatalities hence created stiff penalties for boating under the influence of alcohol.
While it is adviseable for motorists not to drink and drive, it is also not lawful be under the influence when boating as such could cause injury, deaths or property damage and such operator would receive appropriate penalty depending on the outcome of the incident.

Ptolemy believed that Earth was at the center of the universe. Kepler believed that the sun was at the focus of Earth's elliptical orbit. Which of these statements best explains why Ptolemy and Kepler made different observations about the solar system?
The focus of their study was different.
or
They could not match the data with the observations.
Answer:
The correct option is;
They could not match the data with the observations
Explanation:
Ptolemy proposed the geocentric model based on the observation that the from there are equal number of above and below the horizons at any given time, which didn't match the data observed
Kepler believed the Sun was the focus of Earth's elliptical orbit due to disparities between data in Tycho Brahe's astronomical records and the geocentric model of the solar system.
Therefore, Ptolemy and Kepler made different observations about the solar system because they could not match the data with the observations.
Answer:
the second one.
Explanation:
They could not match the data with the observations.
Observa el siguiente dibujo, y sabiendo que el engranaje motriz tiene 14 dientes y gira a 4000 RPM, y el conducido tiene 56 dientes, responde: a) Se trata de una transmisión que aumenta o reduce la velocidad? b) Calcula en número de revoluciones por minuto de la rueda conducida.
Answer:
A) reduce the velocity
B) 1000 rpm
Explanation:
A) Given that the driven gear wheel has more teeth (56) than the driver gear wheel (14), then the velocity is reduced.
B) Given that:
number of teeth * revolutions per minute = constant
then:
14*4000 = 56000
56*rpm = 56000
rpm = 56000/56
rpm = 1000
