A company uses a combination of three components- A, B and C to create three different drone designs. The first design Glider uses 3 parts of component A and 2 parts of components B. Design Blimp uses 2 parts of component B and C, and the last design, Pilot uses one part of each component. A sample of 75 components, 25 A, 25 B, 25 C, will be used to make prototypes for the various designs. If 30 components are selected at random, what is the likelihood two prototypes of each design can be made?

What are some outcomes/consequences of high job satisfaction?

can you identify situations in which your job attitudes directly influenced your behavior?

1.Create a standard Java project (i.e. not a JavaFX project) in NetBeans called Personsages

2.Declare a Scanner variable called keyboardInput and a variable called personAge as type int. Code the statement to read in an integer with a prompt to "Enter your age as an integer:".

3.Code an "if/else if" (also called a multi-way if) block to output the following text based on age ranges personAge might contain:

• 0 through 12: Person is a pre-teen.
• 13 through 19: Person is a Teenager.
• 20 through 29: Person is in their 20's.
• 30 through 39: Person is in their 30's.
• 40 or greater: Person is 40 years or older.

4.Code an "if / else" statement to determine if the age entered in Step 9 is on/before the year 1990 or after 1990 outputting the message that the person was born on/before or after 1990.

5.Declare a String variable called aCityInNY and read in a String from the keyboard with a prompt "Enter Albany, Buffalo, New York, Rochester, or Binghampton to see its population:".

6.Code a switch block to compare the value input to the cities just mentioned. Output "Population is: " with the population of each city (you are not being tested on the actual population). If the user enters any other city or text, output an appropriate error message to the user.

7.Declare an integer variable called intInput and assign it a 0. Declare a Boolean called keepLooping and set to true. Code a while loop with keepLooping as the condition.

8.In the body of the while loop, code a prompt that says “Input a number – enter 999 to exit:”. Use a Scanner method to get an integer from the keyboard and assign it to intInput. Output the number only if it does not equal 999, else set keepLooping false.

9.Declare a variable called loopInt. Code a for loop that uses loopInt and counts from 0 to 9.

10.In the for loop body, output “For Loop Counter = “ + loopInt.

11.After the for loop, set the loopInt variable to 0. Code a do-while loop that ends after loopInt is 9.

12.In the body of the do-while, output “Do-While Loop Counter = “ + loopInt. Code a statement to increase loopInt by 1.

13.After the while loop, declare an int variable called loopIntInner and an int variable called loopIntOuter. Code a for loop that counts loopIntOuter from 0 to 4. This is the outer loop. In the body, code another for loop (this is the inner loop) that counts loopIntInner from 0 to 2. In the body of the inner loop put an output statement that outputs “loopIntOuter: “ + loopIntOuter + “ loopIntInner: “ + loopIntInner.

14.Run the program with 32 as the age prompt in Step 9.

15.Enter at least one valid city for Step 12.

16.Enter at least 2 numbers for 15 and then 999.

Please use python.
Step a: Create two DataFrames df1 and df2 from the following two tables that hold student scores. Each DataFrame has four rows and three columns.

Step b: Join the two DataFrames into df3 so that it only includes the students who appear in both tables. Print df3.

Step c: Set the column 'Name' as the index of df3 using df3.set_index() function. Print the updated df3. You can learn from https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.set_index.html.

Step d: Show the average score of each student in df3.

Research any literature/articles that address globalization and its challenges in the context of management…..Discuss in specific terms the challenges and how they are or can be overcome and their respective applicable solutions. Highlight the strategic approaches that managers develop and implement to gain a sustainable competitive advantage. Is globalization a greater challenge or threat to dynamic organizational structures than static organizational structures? Elaborate how you could device a workable method to resolving the challenges or threats. Provide logically-connected organizational management leaders who have made history in this regard.

B) - 9.0*10¹¹ r N/C

C) - 5.2*10¹³ r N/C

D) 5.2*10¹³ r N/C

The answer is D, I am not sure how they got that answer, can you please explain and show your work. Thanks in advance

You are exploring a distant planet. When your spaceship is in a circular orbit at a distance of 630 km above the planet's surface, the ship's orbital speed is 5500 m/s . By observing the planet, you determine its radius to be 4.48×10^6 m. You then land on the surface and, at a place where the ground is level, launch a small projectile with initial speed 13.6 m/s at an angle of 30.8∘ above the horizontal. If resistance due to the planet's atmosphere is negligible, what is the horizontal range of the projectile? Please explain process

A PC store sells many types of computers. The PC can have either 16 or 8 gigabytes of memory.

The quality of the PCs can be either New, Refurbished, or Dented.

The price list is given as follows:
