Answer:

The answer is "[tex]\bold{Brand \ A \ (35, 350, 18.7) \ \ Brand \ B \ (35, 50, 7.07)}[/tex]"

Explanation:

Calculating the mean for brand A:

[tex]\to \bar{X_{A}}=\frac{10+60+50+30+40+20}{6} =\frac{210}{6}=35[/tex]

Calculating the Variance for brand A:

[tex]\sigma_{A}^{2}=\frac{\left ( 10-35 \right )^{2}+\left ( 60-35 \right )^{2}+\left ( 50-35 \right )^{2}+\left ( 30-35 \right )^{2}+\left ( 40-35 \right )^{2}+\left ( 20-35 \right )^{2}}{5} \\\\[/tex]

     [tex]=\frac{\left ( -25 \right )^{2}+\left ( 25 \right )^{2}+\left ( 15\right )^{2}+\left ( -5 \right )^{2}+\left ( 5 \right )^{2}+\left ( 15 \right )^{2}}{5} \\\\ =\frac{625+ 625+225+25+25+225}{5} \\\\ =\frac{1750}{50}\\\\=350[/tex]

Calculating the Standard deviation:

[tex]\sigma _{A}=\sqrt{\sigma _{A}^{2}}=18.7[/tex]

Calculating the Mean for brand B:

[tex]\bar{X_{B}}=\frac{35+45+30+35+40+25}{6}=\frac{210}{6}=35[/tex]

Calculating the Variance for brand B:

[tex]\sigma_{B} ^{2}=\frac{\left ( 35-35 \right )^{2}+\left ( 45-35 \right )^{2}+\left ( 30-35 \right )^{2}+\left ( 35-35 \right )^{2}+\left ( 40-35 \right )^{2}+\left ( 25-35 \right )^{2}}{5}[/tex]

    [tex]=\frac{\left ( 0 \right )^{2}+\left ( 10 \right )^{2}+\left ( -5 \right )^{2}+\left (0 \right )^{2}+\left ( 5 \right )^{2}+\left ( -10 \right )^{2}}{5}\\\\=\frac{0+100+25+0+25+100}{5}\\\\=\frac{100+25+25+100}{5}\\\\=\frac{250}{5}\\\\=50[/tex]

 Calculating the Standard deviation:  

[tex]\sigma _{B}=\sqrt{\sigma _{B}^{2}}=7.07[/tex]

Answers

Answer:

apple apple

banana

Explanation:

Given - Consider the following code:

x = "apple"

y = x

z = "banana"

To find - print(x + " " + y + "\n" + z)

It will print -

Having sound enhances your App, do you agree with this? Explain.

Answer:

Yes, it does.

Explanation:

I mean, having some sort of audio feedback is obviously useful for a user.

We should discuss some cases here:

1. In case it's a game, sound enhances the experience of the virtual world, by creating what is called an "ambience", or the acoustical surroundings of the environment since you can perceive stuff without the need to look at it.

Given the following class code: public class RecurseSample { public static void main(String[] args) { System.out.println(recurse(3)); } public static int recurse(int n) { int total = 0; if (n == 0) { return 0; } else { total = 3 + recurse(n - 1); } return total; } } What values will be printed when this code is executed?

Answers

Answer:

The output of the given code is "9".

Explanation:

In this question, a class "RecurseSample" inside the class a "recurse" method is declared that holds that holds an integer variable as the parameter, and inside the method a total variable is declared and uses a conditional statement to check the n variable value that is equal to 0 if it is true it will return 0. In the else block it call the method and add value in the total variable, and returns its value. In the main method, the print method is used that prints the above method values.

Here is the API for a robot library.
// moves the robot forward

// checks if a robot can move in any direction
// direction {string} - the direction to be checked
// return {Boolean} - true if the robot can move in that direction, otherwise returns false
function canMove(direction);
Which code segment will guarantee that the robot makes it to the gray square without hitting a wall or a barrier (black square)?

A video streaming website uses 32-bit integers to count the number of times each video is played. in anticipation of some videos being played more times than can be represented with 32 bits, the website is planning to change to 64-bit integers for the counter. which of the following best describes the result of using 64-bit integers instead of 32-bit integers? a. 2 times as many values can be represented. 32 times as many values can be represented. 2^32 times as many values can be represented. 32^2 times as many values can be represented. I know the answer is 2^32 but can someone explain it to me?

Answers

Answer:

2³² times as many values that can be represented

Explanation:

A 64 bit register can hold 2⁶⁴ different values, while a 32 bit register can hold 2³² different addresses

Therefore, a 64 bit can represent 2⁶⁴ ÷ 2³² = 2³² times as many values as can be represented by 32-bit

Therefore, the 64 bit can represent 2³² times as many values that can be represented by a 32 bit integer

• Palmtop or hand-held personal computer, lightweight, small, battery-powered, general-purpose programmable computer. It typically has a miniaturized full-function, typewriter like keyboard for input and a small, full color, liquid-crystal display for output. In addition to an operating system that is compatible with that of a desktop computer, a palmtop will typically contain a word processor, a spreadsheet program, and a calendar and phone book. A variety of other programs can be loaded and executed, and data can usually be transferred to and from a desktop computer. Although some palmtops are like personal digital assistants in that they accept handwritten or touch screen input, they generally differ in that the palmtop has more memory, a keyboard, and a greater variety of available programs.

Katie wants to use VLOOKUP for a column in a table. Which value of the mode parameter should she use to look for an exact match of the searched data?
Katie should use the __ value of mode parameter for an exact match with the searched data.

Answers

Answer:

The exact match mode is the mode parameter that Katie should use to look for an exact match of the searched data

Further Explanation:

The VLOOKUP function in Excel helps us search for and retrieve information from a particular column in a table and lookups a value in the left-most column of the table. It has two modes of matching.

Exact matching – When you perform a range_lookup, an argument FALSE is defined to mean that there is an exact match of the return value.

To achieve this, select a cell in your Excel worksheet

Type =VLOOKUP in the type bar of the Excel sheet

Select the value to look up and then select the data range

Type the column number that you want to search and then type FALSE

Press enter

Answers

Answer:

= PMT(B4/B2, B2 * B3, B1)

Explanation:

The syntax to use is:

= PMT(Rate,NPER, PV)

To answer this question, the following assumptions will be made.

B1 = Present Value i.e. PV

B2 = Number of Payment Period i.e n

B3 = Duration (in years)

B4 = Rate

So, the formula to enter in B6 is:

= PMT(B4/B2, B2 * B3, B1)

The above formula will return the monthly payment in cell B6

Design a TestScores class that has fields to hold three test scores. The class should have a constructor, accessor and mutator methods for the test score fields, and a method that returns the average of the test scores. Demonstrate the class by writing a separate program that creates an instance of the class. The program should ask the user to enter three test scores, which are stored in the TestScores object. Then the program should display the average of the scores, as reported by the TestScores object.
