Answer 1

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]

Answer: it most likely a thrid party app that is causing this

Explanation: Random restart problems are sometimes caused by a bad third party app. To check if that's the case here, try running your tablet on safe mode and observe. If it works normally and won't restart on safe mode for some time, that can mean that an app is causing the trouble.Mar 6, 2021

Write a program in Java that asks the user to enter four weighted assessment grades, calculate the average, then display the average with the message: "Student Pass" if the average is greater than or equal 60 or the message "Student Fail" otherwise. The details of the assessments and weights are as follow: Homeworks: 20% Labs: 15% Midterm: 25% Final: 40%

Answers

Answer:

Explanation:

In order to calculate the weighted average, the grade itself is multiplied by the percentage of the category and then these values are summed. This sum is then divided by the total percentage of the portfolio.

import java.util.Scanner;

class Main {

   public static void main(String[] args) {

       double sumOfWeights = 100;

       

       

       Scanner in = new Scanner(System.in);

       

       System.out.println("Please Enter Homework Grade: ");

       double homework = in.nextDouble() * 20;

       System.out.println("Please Enter Labs Grade: ");

       double labs = in.nextDouble() * 15;

       System.out.println("Please Enter Midterm Grade: ");

       double midterm = in.nextDouble() * 25;

       System.out.println("Please Enter Final Grade: ");

       double finals = in.nextDouble() * 40;

       

       double average = (homework + labs + midterm + finals) / sumOfWeights;

       System.out.println("The Average of these Weighted Grades is " + average);

Which of these is a programming best practice?
Use general variable names such as V1 and V2.
Use lots of comments in the code.
Make lines of code as long as possible.
If you need to repeat a function, paste a copy of it each time you need it.

Answers

Answer:

B

Explanation:

You should question C. That looks like a very poor practice, but sometimes it can't be helped. Try and make short lines

D also looks questionable. You'll wind up with pages and pages of code. A better practice is to create subroutines (functions and procedures in the language I use) and then learn how to pass parameters.

A is not a good idea either because if you look at the code a month later, chances are you won't know the difference between v1 and v2.

The best answer is B. But how many programmers do it?

B. use lots of comments in the code

China in 1100 AD, if I am wrong I'm sorry.

Answer:

Greece

Explanation:

It is believed that the reaction principle, the physical law of rocket motion, was first demonstrated about 360 B.C. by a Greek named Archytas. Far from demonstrating the reaction principle in a weapon, Archytas simply filled a hollow clay pigeon with water. He then suspended the clay pigeon by string over a fire. The heating of the water produced steam, and the clay pigeon could move under its own power as steam escaped through strategically placed holes. Archytas could hardly have imagined that the same basic principle would one day carry men to the Moon.

1.Menciona tres factores o variables que consideras influirán en el oscurecimiento del alimento cortado o pelado expuesto a la intemperie

Answers

La respuesta correcta para esta pregunta abierta es la siguiente.

A pesar de que no se incluyen opciones o incisos para responder a la pregunta, podemos comentar lo siguiente.

Los tres factores o variables que considero influyen en el oscurecimiento del alimento cortado o pelado expuesto a la intemperie son los siguientes.

1.- La exposición al elemento "oxígeno" cuando están a la intemperie.

2.- La temperatura del medio ambiente que afecta directamente al alimento.

3.- Los minerales y los metales que constituyen al alimento cuando tienen contacto con el medio ambiente.

En estos momentos, las sustancias que componen al alimento comienzan a tener reacciones químicas y se empiezan a oxidar cuando permanecen abiertas a temperaturas ambiente.

Es por eso que los expertos recomiendan que una vez abierta la comida -la fruta, la verdura- tiene que refrigerarse lo más pronto posible para poderse conservar un poco más de tiempo.

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

Answers

Answer: Use data from the previous steps because they show better results

Explanation:

A scientific bias occurs when there's a deviation between the observations of a researcher and the accurate representation of data and results.

In this case, the use of data from the previous steps because they show better results will bring about a data bias as it'll lead to inaccuracies of the data being represented.
